Summary Purpose Medialization laryngoplasty can be performed to treat glottic incompetence after endoscopic laser cordectomy. The aim of this study is to evaluate vocal outcome after this phonosurgical procedure and to analyze the critical aspects of the Montgomery and Gore-Tex laryngoplasty technique. Methods A retrospective observational study of patients with glottic incompetence after endoscopic laser cordectomy, underwent medialization laryngoplasty with Montgomery or Gore-Tex implant between January 2013 to December 2018 at the Bufalini Hospital of Cesena, Italy. The pre- and postphonosurgery evaluation included videolaryngostroboscopy, perceptual, evaluation of dysphonia with the GRBAS (grade, roughness, breathiness, asthenia, strain) scale, Voice Handicap Index-10, Maximum Phonation Time. The outcome was evaluated 6 months after the phonosurgical treatment. Results We treated 22 patients, 19 males and 3 females. Eight cases were treated with Montgomery implant and fourteen with Gore-Tex implant. The postphonosurgical videolaryngostroboscopy showed an improvement of the glottic closure in all patients; the scores of the Voice Handicap Index-10 and of the Maximum Phonation Time showed a statistically significant improvement after phonosurgery. The GRBAS scale scores showed a statistically significant improvement of Global Grade, Breathiness, and Asthenia; the parameter Strain remained unaltered both in pre- and postoperative evaluations, because the voice was never pressed due to glottic insufficiency, especially in preoperative observation. The parameter Roughness (R) did not show a significant difference between pre- and postoperative evaluation. Conclusion Medialization laryngoplasty is an effective phonosurgical procedure to improve voice outcome, after extended endoscopic laser cordectomies, in patients with unacceptable results after voice therapy and injection laryngoplasty. In our experience the Gore-Tex implant allows the surgeon to perform a safer and more “tailored” phonosurgery in cases of cordectomies type IV and V, associated or not with radiotherapy and in revision surgery.

Introduction Revision framework surgeries might be required for unilateral vocal fold paralyses. However, outcomes and indications of revision surgeries have not been adequately documented. For a better understanding of indications for the procedure and to help in achieving better vocal outcomes, we performed a retrospective chart review of patients who underwent revision framework surgeries for unilateral vocal fold paralysis. Objectives This study aimed to present clinical features of patients who underwent revision framework surgeries for the treatment of unilateral vocal fold paralysis. Methods Of the 149 framework surgeries performed between October 2004 and October 2019, 21 revision framework surgeries were performed in 19 patients. Self-assessments by patients using the voice handicap index-10 questionnaire, and objective aerodynamic and acoustic assessments performed pre- and post-operatively were analyzed using the Wilcoxon’s signed-rank test for paired comparisons. Results Undercorrection was indicated as reasons for revision surgeries in all cases. The revision techniques included type I thyroplasty, type IV thyroplasty, and arytenoid adduction, and revision surgeries were completed without any severe complication in all cases. Pre- and post-operative voice handicap index-10 scores were obtained in 12 cases, and other parameters were evaluated in 18 cases. Significant improvements were observed in voice handicap index-10 scores, maximum phonation time, mean flow rate, Current/Direct Current ratio, and pitch perturbation quotient. Conclusion Undercorrection was observed in all patients who underwent revision framework surgeries for unilateral vocal fold paralysis, and the initial assessment and planning are thought to be important in order to avoid revision surgeries. Revision surgeries were performed safely in all cases, and significantly improved vocal outcomes were observed, even after multiple procedures. Revision surgery should be considered for patients with unsatisfactory vocal functions after primary framework surgeries for unilateral vocal fold paralysis.

Summary Objective Maximum phonation time (MPT) is a test to measure glottic efficiency for laryngeal pathology screening and treatment monitoring. The normative value of MPT for South East Asia population has yet to be reported. It is postulated that MPT may be affected by body mass index (BMI) despite the paucity of evidence. Therefore, this study was designed to establish the normative value of MPT for a South East Asia population and investigate its relation to BMI. Design & Setting This cross-sectional study was conducted in Universiti Kebangsaan Malaysia Medical Center between May and September 2017. Participants and Methods Three hundred males and females with mean age of 30.23 (±11.04) years were recruited in equal number for each gender (n = 150) and divided into 3 groups of 50 according to their BMI (n = 50). The three groups are non-obese (BMI≤22.9kg/m2); obese (BMI between 23 and 34.9 kg/m2); and morbidly obese (BMI >35kg/m2). BMI and Voice Handicap Index-10 (VHI-10) were obtained. The average of three readings of MPT was measured using a stopwatch while the participants phonate /a/, /i/ and /u/. Unpaired t-test and ANOVA were used to compare means between and across groups. Spearman correlation assessed the correlation between MPT and BMI. Main outcome measures The normative values of MPT of both genders and correlation with BMI were analyzed. Results The MPT normative values for males and females in the non-obese group were of 21.41 (±6.85) seconds and 18.05 (±5.06)seconds respectively for /a/. The MPT for all vowels were significantly higher in males across the BMI groups (P ≤ 0.05). There was low negative correlation between MPT and BMI in both genders. Conclusions This pioneering study documented the normative values of MPT among Malaysians showed that males had longer MPT than females across the BMI groups. Obesity affects the MPT in that as BMI increases, the MPT decreases.

Injection laryngoplasty (IL) is performed to reduce the gap between vocal folds induced by unilateral vocal fold paralysis (UVFP). Voice quality after IL may be different due to other factors that influence voice quality. Voice therapy has been reported to improve voice quality after IL in patients with UVFP. This study evaluated the efficacy of voice therapy combined with IL.Patients with UVFP who underwent IL as primary therapy from March 2017 to June 2019 were evaluated. The enrolled patients were divided into two groups, those who did and did not receive voice therapy after IL. Voice quality was evaluated using perceptual, acoustic, and aerodynamic parameters, and voice handicap index-30 scores one month after IL and after completing each treatment.Of 261 patients who underwent IL during the study period, 40 were enrolled, including 21 who did and 19 who did not receive voice therapy. Voice parameters one month after IL did not differ between these two groups. Jitter, shimmer, noise-to-harmonic ratio, and mean flow rate decreased, while maximum phonation time increased after voice therapy (both P0.05). In the absence of voice therapy, improved voice parameters were maintained for six months after IL. Total voice handicap index-30 scores decreased, from 35.6 to 19.1 (P0.05), in patients who received voice therapy.Voice therapy following IL is beneficial to patients with UVFP. Combined treatment can help to maintain improved voice quality more than six months after IL.

To report the outcome of unsedated office based Thulium laser therapy for Reinke's edema.A retrospective chart review of patients operated between March 2017 and November 2018 was conducted. Twelve patients were included, two of whom had two procedures performed. Demographic data included age, gender, smoking status, and grade of Reinke's edema. Outcome measures included Voice Handicap Index-10 (VHI), perceptual evaluation, extent of disease regression, acoustic analysis, and maximal phonation time.Twelve patients were enrolled in this study, one of whom was lost for follow-up. There were eight females and three males. The mean age was 51.27 ± 9.12 years. Endoscopic evaluation 6-12 weeks after surgery revealed complete and partial regression of disease in three and eight patients, respectively. There was a significant improvement in the mean score of VHI-10 (15.00 ± 9.45 vs 3.07 ± 3.81) and the mean score of GRABS parameters following surgery (P0.05). The mean habitual pitch increased from 125.11 ± 28.48 Hz to 155.86 ± 55.14 Hz (P = 0.070). There was improvement in the mean jitter and shimmer but none reached a statistical significance. There was no significant change in the mean Maximum phonation time (MPT) scores before and after surgery.Unsedated office-based Thulium laser therapy can be considered as an alternative therapy to patients with Reinke's edema who are not willing to undergo conventional microlaryngeal surgery.

Muscle tension dysphonia (MTD) is a common voice disorder in teachers in which subjective and objective dimensions of quality of voice can be impaired. The study aimed to compare voice handicap index (VHI) and dysphonia severity index (DSI) in teachers with and without MTD as well as study correlation between them.Cross-sectional survey.Fifty female teachers were enrolled in the study in two different groups (1) twenty-five teachers with MTD (with mean age of 42.62 ± 3.58 years) and (2) 25 teachers without MTD (with mean age of 44.50 ± 3.49 years). All participants completed the Persian version of VHI and underwent multiparametric measurement of voice by the DSI; these subjective and objective voice measures were compared between two groups and their relation was studied.There was significant difference in the VHI, DSI, and their components in teachers with and without MTD (P0.05). No significant correlation was found between the total score of VHI and DSI score in the teachers with MTD (rTeachers with MTD demonstrated higher voice handicap and lower voice quality compared to the teachers without MTD. Moreover, dysphonia interrupted relation between the results of self-perceived evaluation and multiparametric measurement of voice in the teachers with MTD in while these assessments were parallel in the healthy teachers. Further studies are recommended to transparent relation between objective and subjective voice assessments in healthy population.

Background Long-term dysphonia may persist after thyroid surgery even in the absence of overt nerve injury. Therefore, we evaluated long-term dysphonia after thyroidectomy using a validated survey. Methods Patients undergoing thyroidectomy at a single institution from 1990 to 2018 were surveyed via telephone to complete the Voice Handicap Index-10 Survey. Individuals with documented nerve injury were excluded. Results In total, 308 patients completed the survey (mean age 51 ± 14 years, 78% female). Median time since surgery was 10.7 (interquartile range 2.3–17.5) years. The mean Voice Handicap Index-10 Survey score was 2.6 ± 5.2. Of the 113 (37%) patients who reported subjective dysphonia, the mean Voice Handicap Index-10 Survey score was 7.1 ± 6.5. Twenty-two (7.1%) patients had a Voice Handicap Index-10 Survey score above the empiric normative cutoff of 11, with a mean score of 17.6 ± 6.8. The most frequent complaints included “The clarity of my voice is unpredictable” (N = 71, 23%), “People have difficulty understanding me in a noisy room” (N = 70, 23%), and “I feel as though I have to strain to produce voice” (N = 65, 21%). Conclusion Long-term follow-up of patients after thyroidectomy suggests that more than 30% without nerve injury report dysphonia. Research to further assess the etiology and impact of these changes on quality of life is needed.

Objective Patients with unilateral vocal fold paralysis commonly report dysphonia and dysphagia. Dyspnea also occurs, with studies on treatment-related change producing mixed results. Studies including patient-reported outcomes have focused on single-question global scales. The Dyspnea Index (DI) includes 10 questions, is specific to upper airway-related dyspnea, and may better capture these patients' symptoms. We evaluated change in DI after treatment. Study design Retrospective review. Setting Academic medical center. Methods Forty-three patients with unilateral vocal fold paralysis underwent injection augmentation (n = 25) or framework surgery (n = 18). DI was recorded preprocedure, 2 to 4 weeks afterward, and at approximately 3 months afterward in 19 patients. Voice Handicap Index-10, Glottal Function Index, Cough Severity Index, and Eating Assessment Tool-10 were also recorded. Change in parameters and correlations were assessed. Obesity, cardiac disease, pulmonary disease, and procedure (injection vs framework surgery) were evaluated for effect on DI. Results Twenty-four patients had an abnormal baseline DI (>10). DI decreased from 14.9 ± 13.8 to 6.5 ± 9.3 after treatment (P Conclusion Upper airway-related dyspnea is common in unilateral vocal fold paralysis, occurring in half of this cohort. Correcting glottic insufficiency may alleviate symptoms. Treatment decision making should consider postprocedural change in dyspnea, especially in patients for whom dyspnea is a motivating factor for seeking treatment.

Objective Fibrotic changes in the vocal fold mucosa have been observed in patients with vocal fold scarring, aged vocal fold, and sulcus vocalis, which often lead to severe voice disorders. Previous research suggests that the basic fibroblast growth factor (b FGF) improves variations in vocal fold properties [1 , 2] . Although clinical studies on b FGF treatments have been conducted [3 , 4 , 5] , these studies only demonstrated the efficacy of this drug over a short period. The present study is the first to investigate the long-term efficacy of b FGF treatment. Methods b FGF injections were performed in six patients from January of 2016 to December of 2017 at our institution. Patient follow-up continued for at least two years after the last injection. Three patients had vocal fold scarring, two had aged vocal fold atrophy, and one patient had sulcus vocalis. Each vocal fold was injected with 10 µg of b FGF four times. Voice and stroboscopic examinations were performed after surgery (at one month, three months, six months, one year, two years). Fundamental frequency, maximum phonation time (MPT), mean flow rate (MFR), amplitude perturbation quotient (APQ), pitch perturbation quotient (PPQ), and noise-to-harmonic ratio (NHR), and voice handicap index-10 (VHI-10) were examined and compared statistically between the pretreatment time and at each posttreatment time point. Results The speaking F0 had an obvious decreasing tendency, with significant differences suggesting the increase in volume in the vocal folds. Aerodynamic parameters also showed small improvements. The most remarkable improvement was observed in the acoustic parameters, indicating that the treatment could improve the vocal fold to make vibrations symmetrically and regularly for a long period. Achievement of symmetry and regularity on vocal fold vibrations suggested the property changes had happened in the vocal folds. Consequently, the score of VHI-10 had improved, indicating high patient satisfaction with this treatment. Conclusion b FGF injections could be a reliable treatment option for diseases that deteriorate the property of vocal fold.

Summary Objective The primary goal of the study was to evaluate the influence of cosmetic and functional rhinoplasty on quality of life and voice performance preservation in opera singers. Materials and methods This study was conducted in the ENT Department of Claros Clinic and included 18 opera singers: 16 women (8 sopranos, 5 mezzos, 2 contralto, and 1 unclassified) and 2 men (1 tenor and 1 baritone). Patients underwent either cosmetic or functional rhinoplasty. We excluded patients with previous nasal surgery, allergic or vasomotor rhinitis, laryngeal pathology, nasal pathology except septal deviation, hormonal or psychiatric disorders, psychic lability, or younger than 18 years of age. We evaluated the fundamental frequency, jitter, shimmer, maximal phonation time, Voice Handicap Index-10, and subjective perception of the patient before and 6 months after surgery. Results Rhinoplasty was indicated for aesthetic reasons in 12 cases. Six patients also associated nasal obstruction due to septal deviation. The fundamental frequency presented no variation and jitter, shimmer and the maximal time phonation improved slightly. Voice Handicap Index-10 scores decreased after the intervention (5.3 vs 5) and the overall perception of the surgical intervention was considered positive both aesthetically and vocally. Conclusions Singers evaluated long-term influence of rhinoplasty as positive. Over 88.8% admitted a beneficial effect on vocal emission and function while 11.1% perceived no change regarding their previous voice.

BACKGROUND We assessed the safety and efficacy of supracricoid partial laryngectomy with cricohyoidoepiglottopexy (SCL-CHEP) in patients with laryngeal cicatricial stenosis. METHODS Sixteen patients receiving SCL-CHEP for severe laryngeal cicatricial stenosis between 2017 and 2018 were reviewed. Decannulation rate and tracheostomy closure time were used to evaluate efficacy. The Voice Handicap Index-10 (VHI-10), Voice-related Quality of Life (V-RQOL) scale and Grade, Roughness, Breathiness, Asthenia, and Strain (GRBAS) scale were used to assess vocal function. Fiberoptic endoscopic evaluation of swallowing (FEES) was performed and the Penetration-Aspiration Scale (PAS), Eating Assessment Tool-10 (EAT-10), and Swallow Quality of Life Questionnaire (SWAL-QOL) were used to assess swallowing function. RESULTS Thirteen patients (81.25%) were decannulated successfully. The average tracheostomy closure time was 45.15 days. There was no observed postoperative complications or recurrence of stenosis. VHI-10 and V-RQOL scores showed significantly improved V-RQOL (p

Introduction Type I thyroplasty is a common procedure used to improve dysphonia secondary to glottic insufficiency caused by vocal fold paralysis, paresis, or bowing. Revision often involves more complex procedures that can be complicated by mucosal violation, hemorrhage, infection, and shifted or extruded implants. Intraoperative challenges can be managed successfully using autologous strap muscle rotation flaps. Objectives Review vocal fold medialization with strap muscle as a viable option for thyroplasty, particularly operations with inadvertent mucosal disruption. Methods All operative records of the senior author's 30-year experience were queried for modified, complex, or revision type I thyroplasties. Each of these was reviewed, and only those utilizing autologous strap muscle rotation flaps for vocal fold medialization were included. Changes in voice quality were assessed using strobovideolaryngoscopic assessment of glottic closure and Voice Handicap Index-10 (VHI-10) scores when available. Results Seven patients were found to have undergone eight type I thyroplasty using autologous strap muscle flaps. Improved glottic closure was seen in all patients except one. This patient, complicated by a laryngeal fracture of unknown origin discovered at the time of surgery, had worse voice with strap muscle implantation intraoperatively; therefore, the patient's fracture was reduced, and medialization was postponed. All other patients reported improved voice quality both intra- and postoperatively. Pre- and postoperative VHI-10 scores were available for two of the seven cases with successfully implanted strap muscles. A decrease in VHI-10 was observed in both cases (mean = 11). No postoperative complications occurred in any patient. Conclusion Although revision thyroplasties are relatively rare, they can be challenging. The seven cases presented herein illustrate the successful and safe use of autologous strap muscle rotation flaps for complex, revision type I thyroplasty procedures. They are particularly helpful in cases requiring additional soft tissue between the thyroid cartilage and mucosa in preparation for possible future medialization after Gore-Tex or Silastic implants, and for inadvertent mucosal disruption in which using a foreign implant might pose a risk of infection. Future studies should be performed with larger populations and longer follow-up to confirm the efficacy and safety of this procedure.

BACKGROUND After surgery in the thyroid region, patients may present with phonation or singing difficulty, even within their vocal range. We designed a novel voice evaluation method that reflects subjective and objective voice complications of the surgery. METHODS This tool recorded patients' voice ranges while singing, which was named the singing voice range profile (singing VRP). Patients were asked to sing "Happy Birthday," which has a one-octave scale, at a comfortable tone and intensity. The singing VRP, standard VRP and voice handicap index-10 (VHI-10) results were recorded before thyroidectomy and 1 and 3 months after thyroidectomy for 128 patients. For subgroup analysis, a group where the maximum F0 of standard VRP in 1 month postoperatively was lower than the highest singing F0 of the preoperative singing VRP was defined as "Collapsed group" and the other group was "Preserved group." RESULTS The changes in the highest, lowest and range of singing fundamental frequency (F0 ) had decreased at 1 month postoperatively. Subsequently, they had improved significantly at 3 months postoperatively but were lower than those preoperatively (all P

OBJECTIVE Traditionally, after total laryngopharyngectomy (TLP), patients cannot speak without a prosthesis or an artificial larynx. In Taiwan, most patients use a commercialized pneumatic laryngeal device (PLD). Phonatory tube reconstruction with the anterolateral thigh (ALT) flap is a novel, modified version of synchronous digestive and phonatory reconstruction involving a free muscular cutaneous flap. This study reviewed and compared speech performance between patients who underwent novel flap reconstruction and conventional PLD users. METHOD We retrospectively reviewed patients with laryngeal or hypopharyngeal cancer who underwent TLP from August 2017 to September 2019. The voice handicap index (VHI), speech intelligibility, acoustic and aerodynamic analysis results, and speech range profile (SRP) were compared between patients who underwent ALT phonatory tube reconstruction (ALT group) and those using PLDs (PLD group). RESULTS Twenty patients were included; 13 patients were included in the ALT group, and 7 patients were included in the PLD group. Compared to the PLD group, the ALT group had a better fundamental frequency range (P

OBJECTIVES/HYPOTHESIS VT is often considered the preferred treatment for vocal feminization in transgender patients. However, Wendler glottoplasty offers a surgical option for increasing fundamental frequency and perception of vocal femininity. We aimed to determine whether the addition of glottoplasty to VT results in greater fundamental frequency elevation and improvement in quality-of-life measures. STUDY DESIGN Retrospective case series. METHODS Forty-eight trans female patients were treated for vocal feminization. Twenty-seven patients underwent VT, and 21 patients underwent VT with additional glottoplasty (VTWG). Pre- and posttreatment acoustic measures, Trans Woman Voice Questionnaire (TWVQ), and Voice Handicap Index-10 (VHI-10) data were compared. RESULTS Glottoplasty in combination with VT elevated average speaking fundamental frequency (SF0) to a greater extent than VT alone (P

PurposePrevious studies have reported that voice therapy via telepractice is useful for patients with nodules and muscle tension dysphonia. Nevertheless, telepractice for elderly patients with voice disorders has not yet been investigated. We conducted this study to examine the hypothesis that voice therapy via telepractice is not inferior to conventional voice therapy.MethodEighty patients with dysphonia aged more than 55 years participated in this study from September 2016 to June 2018. After screening the inclusion and the exclusion criteria, 69 patients were randomized into telepractice (33 patients) and conventional (36 patients) groups. The outcome measurements included Voice Handicap Index-10, videolaryngostroboscopy, maximum phonation time, auditory-perceptual evaluation, and acoustic analysis. Pairedttest, Wilcoxon signed-ranks test, and repeated measures analysis of variance were used to examine treatment outcomes.ResultsThe diagnoses of voice disorders included atrophy (n= 33), unilateral vocal paralysis (n= 13), muscle tension dysphonia (n= 7), nodules (n= 6), and polyps (n= 10). No significant differences were observed in age, sex, and baseline measurements between the two groups. Twenty-five patients in the telepractice group and 24 patients in the control group completed at least four weekly sessions. Significant improvements were observed for all the outcome measures (p< .05) in both groups. Improvements in Voice Handicap Index-10 in the telepractice group (24.84 ± 5.49 to 16.80 ± 8.94) were comparable to those in the conventional group (22.17 ± 7.29 to 13.46 ± 9.95,p= .764). Other parameters also showed comparable improvements between the two groups without statistically significant differences.ConclusionsThis is the first randomized controlled trial comparing telepractice and conventional voice therapy in elderly patients with voice disorders. The results showed that the effectiveness of voice therapy via telepractice was not inferior to that of conventional voice therapy, indicating that telepractice can be used as an alternative to provide voice care for elderly patients with vocal disorders.

The aim of this study is the analysis of postural changes of patients affected by vocal disorders post-thyroidectomy, in the absence of post-operative organ damage, through a stabilometry analysis, evaluating the effectiveness of a speech-language intensive treatment in phoniatric and postural quality recovery. 260 patients with vocal dysfunction after surgery without iatrogenic damage were enrolled. 130 patients were subject to post-surgical logopedic rehabilitative training (Group A); other 130 patients were not subject to any post-surgical treatment (Group B). For all patients, vocal and stabilometric parameters were evaluated before and after 2 days and 1 month from surgery. Vocal parameters evaluated were Voice Handicap Index-10, Maximum Phonation Time and objective evaluation of voice with Multidimensional Voice Program (MDVP). Stabilometric parameters evaluated were Sway area (mm2) and Sway velocity (mm/s) in firm surface and foam pad with eyes opened and closed. Regarding the stabilometric parameters, Group A obtained a statistically significant recovery of the correct posture statistically significant compared to Group B, after a month of speech therapy. Vocal parameters (VHI, MPT, MDVP) were statistically different between the two groups (p

Purpose Semi-occluded vocal tract (SOVT) exercises with tubes or straws have been widely used for a variety of voice disorders. Yet, the effects of longer periods of SOVT exercises (lasting for weeks) on the aging voice are not well understood. This study investigated the effects of a 6-week straw phonation in water (SPW) exercise program. Method Thirty-seven elderly subjects with self-perceived voice problems were assigned into two groups: (a) SPW exercises with six weekly sessions and home practice (experimental group) and (b) vocal hygiene education (control group). Before and after intervention (2 weeks after the completion of the exercise program), acoustic analysis, auditory–perceptual evaluation, and self-assessment of vocal impairment were conducted. Results Analysis of covariance revealed significant differences between the two groups in smoothed cepstral peak prominence measures, harmonics-to-noise ratio, the auditory–perceptual parameter of breathiness, and Voice Handicap Index-10 scores postintervention. No significant differences between the two groups were found for other measures. Conclusions Our results supported the positive effects of SOVT exercises for the aging voice, with a 6-week SPW exercise program being a clinical option. Future studies should involve long-term follow-up and additional outcome measures to better understand the efficacy of SOVT exercises, particularly SPW exercises, for the aging voice.

This preliminary qualitative description study explored knowledge from urban Ghanaians about the nature and impact of their self-reported voice problem. Ten Ghanaians were screened for a self-reported voice disorder using the Voice Handicap Index–10 (VHI-10), and they also completed a structured interview with a speech-language therapist. Content analysis was completed from interview responses using quantification of data. Four out of 10 adult Ghanaians demonstrated high VHI-10 scores that indicated a self-reported voice disorder. Themes that emerged included a recurring problem with voice, multiple vocal impairments, limitations with participating in vocal activities, and other health problems. Lack of financial resources and little knowledge about voice disorders were barriers to accessing care. In summary, four adult Ghanaians with a self-reported voice disorder described multiple problems with their voice, limiting their participation in vocal activities. Implications of these preliminary findings include early identification and improving voice care access to avoid handicapping voice problems.

Objectives: Mutational falsetto (MF) is a functional voice disorder involving failure to transition from the high-pitched voice of childhood to the lower-pitched voice of adolescence and adulthood. The low mandible maneuver (LMM) is used by professional singers to relax the larynx and expand the resonance space. It relaxes suprahyoid muscles and pushes the larynx backwards, so it can be used as a therapy for MF. Material and Methods: The data of 20 MF patients treated by the LMM were analyzed in this study. All of the patients were asked to complete the Voice Handicap Index-10 (VHI-10) before the first session, and again 2 weeks after the second visit. The Grade-Roughness-Breathiness-Asthenia-Strain (GRBAS) scale scores and fundamental frequency (F0) were analyzed for each patient. Results: All except 1 patient reported that they completed the exercises without difficulty; the patient who did not perform the exercises cited reasons other than their difficulty. Only 2 patients failed to transition from MF to a lower-pitched voice. The GRBAS scale scores (all parameters) differed significantly between the first and second sessions. The VHI-10 score also changed, i.e., self-perceived voice quality was improved significantly, as was the F0. Conclusions: Our results showed that the LMM is an efficient and rapid technique for treating MF patients and shows high patient compliance.

Vocal dysfunction is one of the major factors that affect the health-related quality of life of patients after thyroidectomy. Conventionally, voice changes after thyroidectomy have been evaluated by videostroboscopy and acoustic analysis. Recently, two-dimensional scanning digital kymography (2D DKG) and high-speed videolaryngoscopy (HSV) have been developed and have shown usefulness in accurately evaluating vocal fold vibration. This study aimed to evaluate changes of vocal fold vibration and voice after thyroidectomy using 2D DKG and HSV.We evaluated the voice and vocal fold movement of 24 female patients who underwent thyroidectomy in a single tertiary hospital from December 2018 to October 2019. We obtained serial 2D DKG and HSV data one day before thyroidectomy, and 1 week and 1 month after surgery. We analyzed the peak glottal area of HSV, amplitude symmetry index, phase symmetry index, and open quotient using the 2D DKG data. The parameters were calculated at three levels of the vocal fold (line 1=anterior, line 2=middle, line 3=posterior). In the same period, we performed a voice analysis evaluating voice frequency, jitter, shimmer, and noise to harmonic ratio. We also assessed maximum phonation time and subjective voice changes with voice handicap index-10 questionnaires.Highest frequency (F-high), frequency range (F-range), and fundamental frequency (F0) decreased at 1 week and 1 month after thyroidectomy compared with preoperative values (P = 0.003, 0.004,0.001 and P = 0.002, 0.015, 0.001 at 1 week and 1 month, respectively). The open quotient of 2D DKG in lines 1 and 2 increased at 1 week after thyroidectomy (P = 0.011, 0.006) and recovered to preoperative levels at 1 month postoperatively (P = 0.189, 0.153). Other quantitative measures by 2D DKG and HSV did not show significant changes between the preoperative and postoperative periods. In a correlation analysis between vocal parameters from the acoustic analysis and the values obtained from 2D DKG and HSV, significant negative correlations were observed between peak glottal area and three factors (F-high, F-range, and F0) at 1 month after surgery (r = -0.589, -0.529, -0.708; P = 0.002, 0.008,0.001, respectively). There were positive correlations between phase symmetry indexes in lines 1 and 2 and shimmer at 1 week after thyroidectomy (r = 0.489, 0.425; P = 0.015, 0.038, respectively). Phase symmetry index in line 3 showed a significant negative correlation with maximum phonation time at both 1 week and 1 month after surgery (r = -0.497, -0.439; P = 0.013, 0.032, respectively). However, there was no correlation between total score on the voice handicap index-10 questionnaires and quantitative measurements of vocal fold vibration.2D DKG and HSV may provide important information on vocal fold vibratory patterns after thyroidectomy, and measurements made with them were correlated with maximal phonation time and acoustic parameters such as F-high, F-range, F0, shimmer.

Summary Objectives This retrospective study examines the influence of voice quality in connected speech (CS) and sustained vowels (SV) on the voice-related disability in patients’ daily living documented by Voice Handicap Index-10 (VHI-10). Methods A total of 500 voice recordings of CS and SV samples from 338 patients with voice disturbances were included, along with the patients' age, diagnoses, maximum phonation time, and VHI-10. Dataset-1 comprised of 338 untreated patients, whereas Dataset-2 included 162 patients before and after phonosurgeries. As a preliminary study, the concurrent and diagnostic validities based on auditory-perceptual judgments were examined for cepstral peak prominence (CPP) and CPP smoothed (CPPS) for CS and SV tasks. Next, simple correlations and multivariate regression analyses (MRA) were performed to identify which of the acoustic measures for the CS or SV tasks significantly influenced the total score or improvement of VHI-10. Results The preliminary study confirmed high correlations with hoarseness levels as well as the excellent diagnostic accuracy of CPP and CPPS for both CS and SV tasks. In Dataset-1, the simple correlations and MRA results showed that cepstral measures in both tasks demonstrated moderate correlations with, and significant contribution to the total score of VHI-10, respectively. However, in Dataset-2, the changes of cepstral measures, as well as the median pitch after phonosurgeries in the CS tasks only, showed significant contributions to the improvement of VHI-10. Conclusion The study demonstrated that the hoarseness levels in both the CS and SV tasks equivalently influenced the VHI-10 scores, and that the post-surgical change of voice quality only in the CS tasks influenced the improvement of voice-related disability in daily living.

The purpose of this study was to cross-culturally adapt and validate the Hong Kong Chinese version of the Children's Voice Handicap Index-10 for Parents (CVHI-10-P(HK)), a parent-proxied quality of life (QOL) questionnaire that pairs with the Children's Voice Handicap Index-10 (CVHI-10(HK)).The English version of the (CVHI-10-P(HK)) underwent forward-backward translation and pretesting. Content validity was computed from an expert panel rating on relevance and test-retest reliability was obtained from parents and/or guardians of six dysphonic and five vocally-healthy children. Other validity and reliability measures were analyzed from CVHI-10-P(HK) completed by parents and/or guardians of 28 dysphonic and 35 vocally-healthy children who had completed CVHI-10(HK).The CVHI-10-P(HK) demonstrated excellent internal consistency (α = 0.091), excellent content validity (item- and scale-level content validity indices = 1.00), good construct validity (between group difference in total CVHI-10-P(HK) score: t(30.904) = -6.449, P0.001, Cohen's d = 1.709) and excellent test-retest reliability (r = 0.966, P0.001). Criterion validity analysis showed a moderate correlation between the total CVHI-10-P(HK) score and auditory-perceptual ratings on overall severity (r = 0.515, P0.001). Area under the curve of the receiver operating characteristic plot was found to be 0.855. The CVHI-10-P(HK) has excellent intrinsic accuracy. A cutoff of score of four may be adopted for the optimal sensitivity and specificity match. A moderate correlation was found between the total scores of CVHI-10-P(HK) and CVHI-10(HK) (r = 0.684, P0.001).The CVHI-10-P(HK) is a valid tool that measures QOL of dysphonic children from the parents' perspective. It is recommended to be used in parallel to the CVHI-10(HK) as part of a comprehensive voice assessment for children in Hong Kong.

Objective: To analyze the clinical efficacy of external beam radiation therapy (EBRT) vs transoral laser microsurgery (TLM) in patients with early glottic laryngeal carcinoma (T1-T2N0) and the effect of treatment choice on vocal function. Methods: A retrospective analysis of patients with T1-T2N0 glottic laryngeal carcinoma who underwent EBRT or TLM between January 2012 and December 2018 in PUMCH. The Kaplan-Meier method was used to analyze local control, progression-free survival and overall survival, and the VHI-30 scale was used to evaluate the effects of EBRT and TLM on vocal function. Results: A total of 185 patients, all with pathologically confirmed squamous cell carcinoma, were enrolled. The median age was 62 years (38-88). N0 disease was confirmed by imaging: 142/185 (76.76%) patients had T1N0 disease, and 43/185 patients (23.24%) had T2/N0 disease. A total of 91/195 (49.19%) patients received an EBRT dose of 66-70 Gy/30-35f, at 2.0-2.3 Gy/f. 94/185 (50.81%) patients received TLM. The median follow-up time was 42 months (12-92), and the 3-year LC, PFS, and OS rates for the EBRT and TLM groups were 96.9% vs 94.1%(p=0.750), 95.3% vs 93.1%(p=0.993) and 93.3% vs 95.4%(p=0.467), respectively. The VHI-30 scales were used at the baseline showed no significant difference between the two groups 19.20±3.324 vs 21.65±9.80 (p=0.250), but the EBRT group had a low voice handicap after treatment, 10.24±6.093 vs 19.45±5.112 (p=0.001) (6 months) and 9.45±5.112 vs 14.97±7.741 (12 months). No CTCAE grade 3 or above side effects were observed in the EBRT group, but 3 cases of vocal cord stenosis were observed in the TLM group. Conclusion: The application of EBRT for early glottic laryngeal carcinoma (T1-T2N0) had an obvious curative effect with high LC and OS rates, no serious side effects, and a low voice handicap rate.

OBJECTIVES/HYPOTHESIS The purpose of the study was to compare the prevalence of vocal fold pathologies among first-year singing students from the classical, musical theatre, and contemporary commercial music (CCM) genres. STUDY DESIGN Prospective cohort study. METHODS Videostroboscopic examinations were rated by blinded expert raters. Vocal pathology was defined as a vocal fold abnormality on the membranous or cartilaginous portions of the vocal folds or hypomobility. Consensus among three of four raters confirmed presence of pathology. Association between genre of singer and presence of pathology, interrater reliability, and intrarater reliability were calculated. Differences in singing voice handicap, and voice use and vocal hygiene were compared. RESULTS Fifty-seven participants were included. Seventeen percent of CCM, 40% of musical theatre, and 0% of classical singers were found to have vocal fold pathology. Interrater reliability was 0.522 between all four raters, 0.591 between the two laryngologists, and 0.581 between the two speech-language pathologists, showing a moderate agreement (P

Objectives: To assess the effect of EVES (Education for a Healthy and Efficient Voice), a voice training program aimed at promoting the use of an efficient and healthy voice in teachers. Sample and Method: Twenty-two teachers in the city of Granollers (Catalonia, Spain) were included in this research. The effect of the EVES program was evaluated focusing on the analysis of physiologic parameters on the one side (stroboscopy analysis), and on perceptual parameters on the other (Q-EVES questionnaire, Voice Handicap Index-10 [VHI-10], and GRBAS [Grade, Roughness, Breathiness, Asthenia, Strain Scale]). Results: The teachers incorporated the vocal strategies in their professional life and reported that the perception of difficulty in using their voice decreased. We observed a significant improvement in VHI-10 markers, in voice management abilities in the classroom, in perceptive and subjective voice parameters, and in some functional lesions. Conclusions: The results suggest that the educational intervention model may have a positive effect on teachers’ vocal care.

Summary Objective We sought to determine the outcomes of office-based autologous fat injection laryngoplasty in the treatment of patients under 50 years old with glottic insufficiency but without neurological problems or acquired organic lesions in the vocal fold. Methods We conducted a retrospective chart review of consecutive patients under 50 years of age who underwent office-based autologous fat injection laryngoplasty for glottic insufficiency. None of the patients presented neurological problems or acquired organic lesions in the vocal fold. Videolaryngostroboscopic data, objective voice assessment, perceptual measurements of vocal quality, and subjective ratings of voice quality were evaluated before and after treatment. Results The 23 patients (7 men and 16 women) in this study presented significant improvements in phonatory function in terms of maximum phonation time, jitter, grade, asthenia, and Voice Handicap Index-10 (VHI-10) values at 3 months. Significant improvements in terms of jitter, noise-to-harmonic ratio, grade, roughness, breathiness, asthenia, and the VHI-10 values were also observed at 6 months. Conclusions Glottic insufficiency in younger patients without neurological problems or acquired organic lesions in the vocal fold can be treated effectively using office-based autologous fat injection laryngoplasty. Significant improvements in phonatory function were observed even 6 months after surgery.

This article provides a concise review of contemporary options for evaluating voice disorders. Focus is given to patient history and patient-derived voice handicap and quality of life assessments, clinician-derived perceptual analysis of voice, and finally flexible and rigid, high-definition laryngoscopy with videostroboscopy to fully evaluate laryngeal function and biomechanics.

Background: The Voice Handicap Index-10 (VHI-10) is used in clinics because of its validity and ease of use by patients. Objectives: The aim of this paper was to evaluate the internal consistency, reliability, and clinical validity of the Serbian version of the VHI-10. Method: In this cross-sectional study, we translated the original English version of the VHI-10 into Serbian, after which it was back-translated into English. The Serbian version of the VHI-10 was completed by 161 patients with voice disorders, divided into 4 groups according disease etiology (structural, neurological, functional, and inflammatory) and 73 healthy control subjects. Results: The VHI-10 internal consistency was 0.88. Spearman’s rank correlation coefficient for VHI-10 test-retest reliability was ρ = 0.991 (p< 0.001). Patients with voice disorders had higher median total VHI-10 scores compared with controls (p< 0.001). The patients’ Grade, Instability, Roughness, Breathiness, Asthenia, and Strain (GIRBAS) scale scores were significantly correlated with the VHI-10 test scores (ρ = 0,682, p < 0.001) and VHI-10 retest scores (ρ = 0.716, p < 0.001). Conclusion: The Serbian version of the VHI-10 had good validity and reliability and can be used by Serbian patients with voice disorders.

Objectives: Voice handicap has generally been measured at a single timepoint. Little is known about its variability from hour to hour or day to day. Voice handicap has been shown to be negatively related to voice-related perceived control in cross-sectional studies, but the within-person variability in voice-related perceived control is also unknown. We aimed to use ecological momentary assessment (EMA) to (1) assess the feasibility of EMA to examine daily voice handicap and voice-related perceived control in patients with voice disorders, (2) measure within-person variability in daily voice handicap and perceived control, and (3) characterize temporal associations (eg, correlations over time) between daily voice handicap and perceived control. Methods: Adults with voice problems were recruited from a large public university medical center in the Midwest. They completed baseline measures, followed by twice-daily assessments, including selected items measuring voice handicap and perceived control, and then repeated the baseline measures at the final timepoint. Feasibility was assessed via completion rates. Within-person variability was measured using standard deviations. Temporal associations were characterized using simulation modeling analysis. Results: EMA of voice handicap and perceived control was feasible in this patient population. Momentary voice handicap varied more than perceived control, though both were variable. Multiple patterns of temporal associations between daily voice handicap and perceived control were found. Conclusions: These findings identified important variability in (1) measures of voice handicap and perceived control and (2) their associations over time. Future EMA studies in patients with voice disorders are both feasible and warranted.

Summary Objective Trial vocal fold injection (TVFI) is employed diagnostically for patients with subtle glottic insufficiency to explore potential for improvement. Clinical experience demonstrates the time to and length of peak benefit of the TVFI is variable. Previous studies collected data 4 weeks or more after TVFI. The aim of this study was to compare subjectively successful and unsuccessful TVFI patient groups. It is hypothesized that patients with subjectively reported success will also have significant improvements in Voice Handicap Index-10 (VHI-10), phase closure percentage, and aerodynamic measures 2 weeks after trial augmentation. Methods/Design Subjects with glottic insufficiency were included in this retrospective review if they underwent office-based, per-oral vocal fold injection augmentation specifically for trial purposes. Patients were divided into “successful” and “unsuccessful” groups based on their subjective experience during the 2-week post-TVFI period. VHI-10, subjective report, phase closure evaluation using frame-by-frame analysis, and aerodynamic data were collected pre- and 2 weeks post-TVFI. Results Of the subjects, 15 of 23 (65%) reported a successful subjective improvement of their symptom, whereas 8 (35%) were unsuccessful (only partial improvement or no improvement). The number of subjects with an improvement in VHI-10 by 5 or more points was not significantly different between groups. The number of subjects that demonstrated complete, long phase closure was significantly higher in the successful group ( P = 0.021). Conclusions The understanding of how to more precisely determine the success of TVFI remains incomplete. Subjective improvement of successful TVFI was captured with basic clinical questioning, yet the VHI-10 was unable to confidently demonstrate this reported success 2 weeks after TVFI.

Summary Our study sought to show the relation between dysphonia and personality traits as explained by Gray's theories. Personality traits were analyzed in a patient group of 141 patients who showed functional and congenital voice disorders. The results were compared to the control group made up of 99 vocally healthy individuals. Their objective voice quality was measured by using the Dysphonia Severity Index, Voice Handicap level was measured using the VHI-10, and a perceptive analysis was conducted with a listening jury. The results showed significant differences in Introversion and Neuroticism and a greater tendency for activating the behavioral inhibition system in the patient group. Such an influence was also evident in voice quality measures. The results were similar to specialized literature.

OBJECTIVES//HYPOTHESIS To determine changes in voice severity when treating chronic cough refractory to medical treatment with cough suppression therapy (CST) in patients with chronic cough and voice complaints. Chronic cough has been reported to be refractory to medical treatment and frequently co-occurs with voice disorders. The possible effects of CST on self-assessed changes in chronic cough and voice disorders have not been demonstrated. STUDY DESIGN Retrospective analysis of the effects of cough suppression therapy (CST) on self-assessed changes in chronic cough and voice disorder severity in patients with both chronic cough and voice disorders. METHODS Forty-three adult patients with the primary complaint of chronic refractory cough underwent pre- and post-treatment diagnostic examinations, completed pre- and post-treatment Voice Handicap Index-10 (VHI-10) and Cough Severity Index assessments, and were treated by a licensed speech-language pathologist using CST. Twenty-seven subjects were assigned to the cough (C) group and 16 to the cough-voice (CV) group based on the severity of their VHI-10 scores. RESULTS Post-test analysis showed significant improvement in cough severity for both groups and significant improvement in voice severity for the CV group. The VHI-10 scores for the C group did not change significantly. The median number of treatment sessions was 3, with a range of 1-13 sessions. Correlation between changes in severity and number of treatment sessions was not found to be significant at the tested level. CONCLUSIONS CST represents a unifying approach for treatment of patients with CRC and comorbid voice disorders. CST offered cross-over effects to the voice when subjects were treated for their primary complaint of chronic cough. This treatment of the primary complaint improves function in systems that share a common pathway. LEVEL OF EVIDENCE 4 Laryngoscope, 131:2747-2751, 2021.

Objectives This study aimed to assess the efficacy of Kinesio taping on male patients with mutational falsetto undergoing voice therapy. Design Double blind, randomized, sham-controlled clinical trial. Participants Interviews were conducted with thirty seven mutational falsetto patients. Included 32 participants were randomized and divided into two groups. Two were dropped out due to irregular attendance, 30 participants were included in final analysis. Interventions The study group was treated with voice therapy and applications of three different therapeutic Kinesio taping techniques with seven Kinesio tapes four times over two weeks, and the control group was treated with voice therapy, and applied to sham Kinesio taping. Outcome measures The values of fundamental frequency, jitter, shimmer, noise-harmonic ratio, maximum phonation time, Voice Handicap Index-10 scores, and Grade–Roughness–Breathiness–Asthenia–Strain Scale scores were recorded at the baseline and after the two weeks. Results There were significant differences between the study group and the control group with respect to the values of fundamental frequency (P = 0.011), jitter (P = 0.041), shimmer (P = 0.036), noise-harmonic ratio (P = 0.003), maximum phonation time (P ≤ 0.001), Voice Handicap Index-10 scores (P = 0.036), and Grade–Roughness–Breathiness–Asthenia–Strain Scale scores (P = 0.007; P ≤ 0.021; P = 0.022; P = 0.002; P = 0.021, respectively) at the end of the study. Conclusions The study demonstrated that Kinesio taping with voice therapy is an efficient and effective technique for treating mutational falsetto patients.

Objectives Laryngeal and voice findings of adductor spasmodic dysphonia (AdSD) and muscle tension dysphonia (MTD) are similar, and it is difficult to distinguish between both disorders. The purpose of this study is to ascertain the effect of voice therapy on MTD and AdSD and clarify their difference. Methods A total of 49 patients, including 22 patients with MTD (MTD group) and 27 patients with AdSD (SD group), were included in the study. The MTD scores were evaluated, and aerodynamic analysis (maximum phonation time [MPT], mean airflow rate [MFR], highest pitch, lowest pitch, and pitch range), perceptual evaluation (Strangulation, Interruption, and Tremor), acoustic analysis (PPQ, APQ, NHR, and DVB), and subjective assessment (voice handicap index-10 [VHI-10]) were performed before and after voice therapy. Results The MTD score, highest pitch, pitch range, strangulation, PPQ, APQ, NHR, and VHI-10 showed significant improvement after treatment in the MTD groups. On the other hand, the effect of voice treatment on AdSD was poor despite the improvement in the MTD score. Conclusions This study could serve as a basis for conducting prospective studies to verify the effects of voice therapy on MTD and AdSD.

BackgroundThis study evaluated the correlation between patient and clinician subjective voice analysis in a group of patients suffering from muscular tension dysphonia. This disease does not usually present with organic lesions, and voice analysis is crucial to evaluate it.MethodsA retrospective study with 75 patients was performed. Correlation between grade, roughness, breathiness, asthenia and strain scale and voice handicap index-10 was analysed. Any possible influence of the type of muscular tension dysphonia on these two scales was studied.ResultsThere are only a few studies that correlate voice handicap index-10 and the grade, roughness, breathiness, asthenia and strain scale; however, none of them are specific for patients suffering from muscular tension dysphonia. A moderate correlation (r = 0.56) was found. No influence of muscular tension dysphonia type on voice handicap index-10 score was found, but muscular tension dysphonia type 4 had worse grade, roughness, breathiness, asthenia and strain scale scores than other muscular tension dysphonia types. This could be explained if muscular tension dysphonia type 4 is considered to be the most severe form of this disease.ConclusionThe use of assessment scales based on the opinion of both the clinician and patient must be considered as complementary clinical tools in order to perform a complete assessment of dysphonia.

Objective Compare long‐term voice outcomes in patients treated with FIM or BML for nonparalytic dysphonia. There is controversy whether fat injection medialization (FIM) is a durable alternative to bilateral medialization laryngoplasty (BML) for nonparalytic dysphonia (atrophy, sulcus, scar, paresis). Both interventions yield improved voice quality, yet comparison of patients' long‐term perceptions of their voice after these procedures has not been performed. Methods Retrospective review of patients who underwent FIM or BML for nonparalytic dysphonia was performed from 2008‐2018. Charts were reviewed for demographic information, preoperative diagnosis, intervention, Voice Handicap Index‐10 (VHI‐10), and follow‐up time. Results Forty‐nine patients met our criteria. Fifty procedures were performed (25 FIM, 25 BML). One patient underwent BML with subsequent FIM. There was no significant difference in pre‐treatment or post‐treatment VHI‐10 scores between both groups (Pre‐FIM 21 Post‐FIM 10.28; Pre‐BML 22.48, Post‐BML 10.88). Total median follow‐up time was 11.3 months (FIM 14.8 months, BML 9.5 months). Using VHI‐10 scores recorded at each patient's latest follow‐up visit, both groups demonstrated significant decrease (P, There is controversy whether fat injection medialization is a durable alternative to bilateral medialization laryngoplasty for non‐paralytic dysphonia (atrophy, sulcus, scar, paresis). Yet comparison of patients' long‐term perceptions of their voice after these procedures has not been performed. In this study we compare long‐term voice outcomes in patients treated with fat injection medialization or bilateral medialization laryngoplasty for non‐paralytic dysphonia.

PurposeTo investigate the efficacy and safety of allograft and hydroxyapatite (HA) as substitutes for autograft in anterior cervical discectomy and fusion (ACDF).MethodsIn this study, 49 patients (80 segments) treated with ACDF were included and allocated into three groups [group A, autogenous iliac bone,n= 18; group B, allogeneic bone,n= 16; group C, HA,n= 15]. The clinical efficacy and fusion status were compared among each group. Complications were recorded in detail, and the Bazaz classification and Voice Handicap Index-10 (VHI-10) were used to detect dysphagia and dysphonia.ResultsPatients exhibited similar clinical efficacy among the groups during the final follow-up. All patients in groups A and B achieved fusion compared to only 73.3% of patients in group C. Groups A and B had similar fusion score, both of which greater than that of group C. No cage subsidence was observed in group A; however, 6.3% of patients in group B and 53.3% in group C had cage subsidence. Two patients in group A (11.1%) had persistent pain at the donor site. One patient in group B had dysphagia and dysphonia (6.3%), while one patient in group C had dysphonia (6.7%).ConclusionIn ACDF, the autogenous iliac bone was the most ideal bone graft. The allogeneic bone was an acceptable substitute but risked cage subsidence and dysphagia. HA had a much lower fusion rate and a high risk of cage subsidence. Better substitutes should be further explored for ACDF.

Audiologopēdija Veselības aprūpe Audiologopaedics Health Care Darba nosaukums: Dzīves kvalitātes novērtējums pacientiem pēc laringektomijas ar ievietotu balss protēzi: Sistemātisks pārskats. Aktualitāte: Pacientiem pēc veiktas totālas laringektomijas zūd iespēja komunicēt verbāli. Tādas rehabilitācijas metodes kā elektrobalsenes izmantošana vai ezofageālas runas apguve spēj atjaunot verbālo komunikāciju, bet būtiski izmaina balss īpašības, kas var pacientam likt justies neērti esot sabiedrībā. Sociālā izolēšanās un atteikšanās no verbālas komunikācijas var nopietni pazemināt dzīves kvalitāti. Balss protēzes ļauj atjaunot runu maksimāli pietuvinot to normālai runai, bet līdz šim nav atrodami kvalitatīvi pētījumu apkopojumi par to, vai un kā balss protēze ietekmē pacientu dzīves kvalitāti, kā arī nav analizēts, cik kvalitatīvi ir esošie pētījumi šajā jomā. Pētījuma mērķis: Sistemātiski apkopot un analizēt pieejamos pētījumus par to, kāda dzīves kvalitāte ir pacientiem pēc laringektomijas ar ievietotu balss protēzi. Metodes: Zinātniskās literatūras izpētei izmantotās datubāzes – PubMed, ScienceDirect, EBSCO Host, Cochrane Library, Scopus un BASE. Pētījumu kvalitātes izvērtēšanai izmantota PEDro skala. Tika formulēts pētnieciskais jautājums pēc PICO metodes, formulēti atslēgas vārdi un atlasīti pētījumi datubāzēs. Atlases process atspoguļots PRISMA Flow diagrammā. Visos pētījumos dzīves kvalitāte tika mērīta ar diviem instrumentiem - ar balsi saistītas dzīves kvalitātes novērtēšanas anketa un ierobežojumu, kas radušies balss traucējumu dēļ novērtēšanas anketa. Rezultāti: Pārskatam tika atlasīti pieci pētījumi, kuri analizēti un savā starpā salīdzināti. Apkopojot datus var apgalvot, ka, pacientiem ar ievietotu balss protēzi, ir minimāli ar balsi saistīti ierobežojumi, bet jāņem vērā arī dažādi faktori, kas to ietekmē. Multidisciplinārajai komandai pirms balss protēzes ievietošanas ir jānovērtē - pacienta izglītības līmenis, profesionāļu pieejamība dzīves vietas tuvumā, ar balss protēzi saistītas iespējamās komplikācijas kā arī pacienta vēlmes un iespējas. Secinājumi: Pēc darba autora izvēlētās publikāciju meklēšanas stratēģijas un atlasītajiem pētījumiem var secināt, ka pacientiem, kuriem pēc totālas laringektomijas ir ievietota balss protēze, ir minimāli ar balsi saistīti dzīves kvalitātes ierobežojumi. Title of the bachelor’s thesis: Quality of life assessment in patients undergoing laryngectomy with an implanted voice prosthesis: Systematic review. Topicality: Patients are loosing verbal communication function after undergoing total laryngectomy. Voice rehabilitation methods such as electrolarynx or acquisition esopohageal speech can restore it, but significantly change the characteristics of the voice, which can make the patient feel uncomfortable in society. Social isolation and abandonment of verbal communication can seriously lower the quality of life. Voice prostheses allow speech to be restored as close as possible to normal speech, but so far no qualitative research has been found on whether and how a voice prosthesis affects patients' quality of life, nor is there any analysis of the quality of existing research in this area. The objective of the study: A systematic review of the literature was conducted to summarize and analyze available research on quality of life in patients with tracheoesophageal puncture after laryngectomy. Materials and methods: Databases used for research of literature - PubMed, ScienceDirect, EBSCO Host, Cochrane Library, Scopus and BASE. The PEDro scale was used to assess the quality of the studies. The research question was formulated according to the PICO method.. The researech selection process is shown in the PRISMA Flow diagram. In all studies, quality of life was measured using two instruments: a voice-related quality of life scale (V-RQoL) and Voice Handicap Index (VHI). Results: Five studies were selected for review and analyzed. When summarizing the data, it can be stated that patients with an implanted voice prosthesis have minimal voice-related limitations, but various factors that affect it must also be taken into account. Before placing a voice prosthesis, the multidisciplinary team must assess the patient's level of education, the availability of professionals near the place of residence, the possible complications associated with the voice prosthesis, as well as the patient's wishes and possibilities. Conclusions: According to the author's search strategies and selected research, it can be concluded that all those who have had voice prostheses after total laryngectomy have minimal restrictions on voice-related quality of life.

Introduction: The health voice production depends on vocal folds vibration and resonance. Anatomical changes of the vocal folds soft tissue (epithelium, ligament, muscle) can cause functional problems results in voice disorders. The vocal folds react to smoking, from irritate the mucous to the tissue changes or dysplasia that degradation of voice performance in daily living.Aim: This study determined the influence of smoking habits to the voice handicap score by Voice Handicap Index score (VHI).Patients and Methods: The design was a retrospective cohort study from 96 adults that identified level of voice fatigue through VHI. They were divided into 3 groups: a group of active smokers, passive smokers and nonsmokers. Chi-square test and regression nominal test was used in this study.Results: Voice fatigue (VHI score > 20) in both active smokers (13.54%) and passive smokers (15.62%) compared with nonsmokers (6.25%), by Chi-square test results was p = 0.047 (p

ObjectiveTo evaluate voice intensity as the primary outcome measurement when treating unilateral vocal fold paralysis patients.MethodsThis prospective observational study comprised 34 newly diagnosed unilateral vocal fold paralysis patients undergoing surgical interventions: injection laryngoplasty or medialisation thyroplasty. Voice assessments, including maximum vocal intensity and other acoustic parameters, were performed at baseline and at one and three months post-intervention. Maximum vocal intensity was also repeated within two weeks before any surgical interventions were performed. The results were compared between different time points and between the two intervention groups.ResultsMaximum vocal intensity showed high internal consistency. Statistically significant improvements were seen in maximum vocal intensity, Voice Handicap Index-10 and other acoustic analyses at one and three months post-intervention. A significant moderate negative correlation was demonstrated between maximum vocal intensity and Voice Handicap Index-10, shimmer and jitter. There were no significant differences in voice outcomes between injection laryngoplasty and medialisation thyroplasty patients at any time point.ConclusionMaximum vocal intensity can be applied as a treatment outcome measure in unilateral vocal fold paralysis patients; it can demonstrate the effectiveness of treatment and moderately correlates with self-reported outcome measures.

Assess respiratory muscle strength, voice and the quality of life of patients with traumatic cervical and thoracic spinal cord injury.Preliminary analytical case control study of 28 adult men, aged between 18 and 65 years, divided into two groups: a research group consisting of 14 patients with cervical and thoracic spinal cord injury, and control group (CG) with 14 noninjured individuals. The subjects had their maximum inspiratory and expiratory pressures measured, underwent voice handicap index-10 assessment, had their voices recorded for auditory perception analysis, using the voice deviation and GRBASI scales, and for acoustic analysis, based on extraction of the parameters selected and completed a quality-of-life questionnaire (WHOQOL-bref protocol).Intergroup comparison indicated that the research group exhibited lower respiratory muscle strength in relation to the CG, MIP and MEP P-values0.001 and0.001, respectively; and in relation to the device's reference value, MIP and MEP P-values0.001 and0.001, respectively; the patients reported no voice handicaps according to the voice handicap index; overall vocal deviation severity on the voice deviation was higher in the CG, P = 0.040; there was greater occurrence of roughness and instability on the GRBASI scale, P= 0.040; there was greater difficulty in modulating vocal frequency (P= 0.002) and resonance, with a laryngopharyngeal focus; the acoustic parameters were normal; and lower scores were obtained in the physical domain of quality of life (P0.001).The individuals with traumatic spinal cord and thoracic injury exhibited changes in respiratory measures, vocal deviation and dissatisfaction in the physical domain of the WHOQOL-bref protocol.

Introduction: The purpose of the present study was to determine the possible effect of allergic rhinitis (AR) on voice change in children with acoustic analysis and Turkish children’s voice handicap index-10 (TR-CVHI-10). Methods: This is a case-control study. Forty-one children with AR, and a positive skin prick test, as well as 39 children of controls who had produced a negative skin prick test and lacked a history of allergic disease, were selected for the study. Each assessment included recordings for the purposes of acoustic voice analysis (fundamental frequency [f0], jitter %, shimmer %, and harmonics-to-noise ratio (HNR)), and aerodynamic analysis (maximum phonation time (MPT) and s/z ratio). All participants completed TR-CVHI-10. Results: The mean TR-CVHI-10 score of the AR group was significantly higher than the control group (p = 0.013). No difference was observed between the AR and control groups in terms of jitter, shimmer, HNR, and MPT values and s/z ratio (p > 0.05). Conversely, the f0 value was more pronounced in controls (270.9 ± 60.3 Hz) than in the AR group (237.7 ± 54.3 Hz) (p = 0.012). Conclusion: The study’s results revealed that AR can have an effect on fundamental frequency and voice quality in children. The diagnostic process should include AR as a potential cause of voice disorders in children.

Summary Introduction The VHI-10 is a patient-reported outcome measure used to record the patient's perception of impairment or handicap due to a voice problem. Scores above 11 are abnormal and indicate voice handicap. Amongst a treatment-seeking population in a large tertiary voice center, scores below the VHI-10 cutoff score of 11 were frequently noted. The aim of this study was to examine the number of people seeking voice therapy for dysphonia who scored below the established VHI-10 cutoff score. Methods A retrospective chart review was completed of all patients attending a voice evaluation with a speech-language pathologist by referral of a laryngologist between February 1, 2017 and February 28, 2018. Patients aged 18+ years with a primary diagnosis of dysphonia were included. Sex, age, primary diagnosis, and VHI-10 score were recorded. Patients were categorized as scoring above or below the cutoff score of 11. Logistic regression was performed to determine the variables that predicted scoring below the VHI-10 cutoff. Results A total of 225 patients were included. There were 91 males (40.4%) and 134 females (59.6%). Sixty-one patients (27.1%) scored below the VHI-10 cutoff of 11 at their evaluation. Younger age and male sex were predictive of scoring below the VHI-10 cutoff score. Diagnosis was not predictive of scoring above or below the cutoff score. Conclusion A notable proportion of treatment-seeking patients scored below the VHI-10 cutoff of 11. If treatment-seeking behavior is related to patient perception of voice handicap, one would expect fewer patients to score below the cutoff. Possible explanations might include that the VHI-10 did not sufficiently capture patient perception of handicap in the study population or the published cutoff score may be too high. Alternatively, another motivator besides handicap may have spurred treatment-seeking behavior. Given these findings, additional or alternative patient-reported outcome measures may be useful in developing a complete clinical picture regarding voice handicap.

Objective Understanding transgender voice is in nascent stages. This study describes voice characteristics in treatment-seeking trans women by comparing two validated questionnaires-Voice Handicap Index-10 (VHI-10) and Transsexual Voice Questionnaire (TVQMtF )-and reports incidence of abnormal stroboscopy findings and acoustic characteristics. Methods Retrospective review of transgender patients presenting to tertiary-care laryngology center between February 2018-February 2019. Mean VHI-10, TVQ, and Singing VHI-10 (SVHI-10) scores; audio-perceptual grade; acoustic measures; and stroboscopy findings were analyzed. VHI-10 and SVHI-10 vs TVQMtF were compared. Results Sixty-one trans female patients (mean age: 32 ± 11 years) were analyzed. Mean duration since start of transition was 41.5 ± 61 months. Sixty-nine percent presented full-time female in all contexts. Pathologic stroboscopy findings were found in 5%. Mean questionnaire scores were 16 ± 10 (VHI-10), 19 ± 13 (SVHI-10), and 81 ± 22 (TVQMtF ). Correlation between VHI-10 and SVHI-10 versus TVQMtF was weak, R = 0.47 (P = .053) and R = 0.35 (P = .17), respectively. Mean audio-perceptual grade was 0.27 ± 0.15. Mean Cepstral Spectral Index of Dysphonia (CSID, sustained vowel) was 8.5 ± 21.9. Mean Cepstral Peak Prominence (CPP) Fo and CPP Fo SD in rainbow passage were 157.3 ± 16 and 59.4 ± 15.9, respectively. Conclusion Trans women report perceived voice handicap in speaking and singing, which appears separate from gender-related voice/communication concerns. This study is the first to report stroboscopy findings in transgender individuals, with 5% being abnormal. Stroboscopy is encouraged before initiating voice intervention in transgender patients. Preliminary evaluation suggests weak correlation between VHI-10 or SVHI-10 and TVQMtF but requires further investigation. TVQMtF may provide information which more specifically reflects voice concerns of trans women as compared to VHI-10 and SVHI-10. Level of evidence 4 Laryngoscope, 131:1071-1077, 2021.

Summary Objective The inclusion of subjective methods for evaluating Voice Disorders is proven an essential factor for diagnosis as these methods include self-reported questionnaires (eg, Voice Handicap Index-VHI) for everyday clinical practice. In turn, by obtaining cut-off scores of self-perceived questionnaires intended for assessment procedures of different voice disorders (eg, patients with neurological problems), the clinicians might be helped toward finding their patients’ needs leading to better monitoring, and treatment suggestions. Consequently, the purpose of this study was to estimate the cut-off scores for the Greek VHI relevant to patients with neurogenic voice disorders. Methods Ninety subjects participated in this research. Sixty-six of them served as the control group while the remaining 24 patients exhibited Neurogenic Voice Disorders (eg, spasmodic dysphonia or vocal fold paralysis). They filled in the VHI and the Voice Evaluation Template. All participants were examined with the use of video laryngeal endoscopy and stroboscopy. Results The analysis revealed higher medians in all domains (of the VHI) for the patients compared to the control group. The cut-off points were estimated at the values of 24.50 (Total Score–AUC 0.932, P = 0.000), 9.00 (Functional Domain–AUC 0.917, P = 0.000), 10.00 (Physical Domain–AUC 0.948, P = 0.000), and 9.00 (Emotional Domain–AUC 0.830, P = 0.000). Conclusion The estimated cut-off scores are in agreement with previous studies. These scores could probably used to enhance therapeutic monitoring of patients who suffer from neurogenic voice disorders. This study underlines the importance of considering different cutoff points for individuals with voice disorders due to diverse neurogenic etiologies.

Objectives Vocal fold nodules (VFNs) are benign lesions at the junction of the anterior and middle third of the vocal folds. Although VFNs are often a result of vocal cord trauma due to vocal abuse, childhood allergic diseases, and medications may be a cause. We aimed to investigate the association of detected VFNs with allergic diseases in childhood patients with vocal abuse. Methods This is a prospective, cross-sectional, case-control study. Caucasian children in ages 3–12, who speak loud, vocal abuse confirmed with Turkish Children's voice handicap index-10 (TR-CVHI-10) above 9 were enrolled to the study. 33 children with VFN were included as the study group and age-matched 26 healthy children without VFN were included as the control group. Children questioned and tested for allergic diseases with Allergometric tests. Results Asthma was detected in 42.4% of the study group and absent in the control group. The history of inhaler or nasal steroid use was positive in 30.3% of the study group and 7.7% of the control group (p = 0.032). Dysphonia and the presence of allergic diseases were determined as independent risk factors for the study group (p = 0.001; 0.021, respectively). The median values of blood lymphocyte counts were significantly different among study and control groups (2900 μl vs 2335 μl, respectively; p = 0.04). Conclusion Investigating allergic diseases, especially asthma, for success in the treatment of pediatric patients with VFNs is of utmost importance.

To assess, through both objective and subjective methods, the complaints of dysphonia among adults with rheumatoid arthritis (RA). The secondary purpose of the study is to determine whether complaints of dysphonia are related to depression and disease activity.This is a prospective cohort study.Eighty subjects (38 RA and 42 healthy volunteers aged 18-65 years old) were included in the study. Participants were evaluated using the Voice Handicap Index-10 (VHI-10) to assess voice complaints. Laryngeal findings of participants with RA were performed by videolaryngoscopy. Maximum phonation time (MPT) measurements and acoustic voice analysis (PRAAT software) were performed to evaluate the presence of objective dysphonia. Disease activity of individuals was calculated by using Disease Activity Score-28 (DAS-28) scale. Beck Depression Inventory (BDI) was applied to evaluate the symptoms of depression in participants.The prevalence of laryngeal symptoms of participants with RA was %42.1. According to the cut-off score of VHI-10, 15.8% of the participants in the study group had voice complaints. Comparing the MPT and acoustic voice analyses values of the study and control group, the MPT of the RA participants were statistically lower (P0.05). Perturbation parameters of male participants in the study and control groups were statistically different. 15.8% of participants in RA group had symptoms of depression. However, there was no statistically significant difference between BDI and acoustic voice parameters.RA may be associated with voice disorders. Male patients with RA had worse jitter parameters, but the number of participants was low. Dysphonia may not be associated with depression and disease activity in RA patients.

Objectives The purpose of this study was to explore the effects of injection laryngoplasty (IL) with hyaluronic acid in patients with vocal fold paralysis (VFP). Methods A total of 50 patients with VFP participated in this study. Pre- and post-IL assessments were performed, which included analyzing the sustained vowel /a/ phonation, and the patient reading 1 Korean sentence from the "Walk" passage that comprised 25 syllables in 10 words. To investigate the effect of IL on vocal fold function, acoustic analysis (acoustic voice quality index, cepstral peak prominence, maximum phonation time, speaking fundamental frequency) was conducted and auditory-perceptual (grade and overall severity), visual judgment (gap), and self-questionnaire (voice handicap index-10) assessments were performed. Results The patients with VFP showed statistically significant differences between pre-and post-IL assessments for acoustic and auditory-perception, visual judgment, and self-questionnaire assessments. Conclusion The patients with VFP showed positive change in vocal fold function between pre- and post-IL measurements. The findings showed that IL with hyaluronic acid is an effective method to improve vocal fold function in patients with VFP.
