Arthritis may affect the larynx and produce symptoms such as hoarseness and vocal fatigue.ObjectiveThis paper aimed to evaluate the laryngeal manifestations of rheumatoid arthritis.MethodsThis is prospective study assessed 27 patients with rheumatoid arthritis with the aid of videolaryngostroboscopy, auditory-perceptual analysis of the speech using the GIRBAS scale, acoustic analysis and the Voice Handicap Index questionnaire.ResultsNineteen patients had laryngeal complaints, the main ones being intermittent dysphonia and sensation of a foreign body in the throat. The most frequent laryngoscopical finding was overlapping arytenoids. Three patients had low pitch, nine patients had mild dysphonia and roughness. Median acoustic measures were: F0, 198.39 Hz; Jitter, 0.815; Shimmer, 4.915; and NHR, 0.144. Regarding the Voice Handicap Index, the median score was zero in all domains. There was a statistically significant correlation between voice complaints and the domains of this index. Functional classes were significantly correlated to: overlapping arytenoids (p = 0.001), PPQ (p = 0.0257), Shimmer (p = 0.0295), APQ (p = 0.0195), and the VHI physical (p = 0.0227) and total domains (p = 0.0425).ConclusionLaryngeal complaints were reported by 70.4% of the patients and laryngoscopical alterations were observed in 48% of the subjects. Voice acoustic evaluation and self-perception were altered.

The relative measurement of the anterior commissure synechia (S) is a crucial factor worsening voice quality and the perceptual analysis score has a strong correlation to the synechia's impact. The aim of this study is to correlate the laryngeal configuration regarding the anterior commissure synechia and its relationship with the acoustic vocal parameters. Fifteen male patients underwent frontolateral partial vertical laryngectomy and reconstruction with bipedicle sternohyoid muscle flap for the treatment of T1b/T2 glottic cancer. The patients were free of disease, and the evaluation was performed after a minimum postoperative period of 12 months. Measurements of the anterior commissure synechia and the free border of both the preserved and the reconstructed vocal folds were simultaneously performed with the acoustic analysis of the voice. We calculated the mathematical proportion between the midsagital dimension of the synechia of the anterior commissure and the measurement of the free border of the intermembranous region of each vocal fold-the preserved one and that reconstructed with the bipedicle sternohyoid muscle flap. The acoustic evaluation showed an important increase in the fundamental frequency, and the values of all parameters were changed regardless of the anterior commissure synechia findings. These results suggest that the acoustic voice parameters are always changed because of the aperiodic pattern regardless of the anterior commissure synechia findings.

After the surgical treatment for early glottic carcinoma, the patients end up with voice disturbances in different grades. The aim of this study was to characterize the laryngeal configuration regarding the anterior commissure synechia and its relationship to the perceptual vocal quality. Twenty-five patients underwent frontolateral vertical partial laryngectomy and reconstruction with bipedicle sternohyoid muscle flap resulting from T1b/T2 glottic squamous cell carcinoma from January 1996 to December 2004. Of the 25 patients, 24 were male with a median age of 61 years. The patients were free of disease and the evaluation was performed after a minimum postoperative period of 12 months. Measurements of the anterior commissure synechia and the free border of both vocal folds were simultaneously performed with the perceptual analysis of the voice through GRBAS scale. We calculated the mathematical proportion between the midsagittal dimension of the synechia of the anterior commissure and the measurement of the free border of the intermembranous region of each vocal fold. The higher the relative measurement of the anterior commissure synechia, the worse the overall grade of hoarseness (G) for both vocal folds (P0.001), the worse the roughness (R) for both vocal folds (P0.001), and the worse the strained quality (S) for both the reconstructed (P=0.0086) and the preserved (P=0.0026) vocal folds. These results suggest that the relative measurement of the anterior commissure synechia is a crucial factor worsening voice quality and that the perceptual analyses score has a strong correlation to the synechia's impact.

Background. Voice alterations after thyroidectomy can be found even with preserved function of laryngeal nerves. The purpose of this study was to evaluate voice before and after thyroid surgery and the role of orotracheal intubation on voice changes. Methods. We conducted a prospective nonrandomized study of patients who underwent thyroid surgery and compared the results with a control group of patients who underwent breast surgery. Subjects underwent a videolaryngoscopic exam, a sub- jective and an objective voice analysis and a Voice Handicap Index (VHI) questionnaire before and after surgery. Results. A total of 100 patients who underwent thyroidec- tomy and 30 who underwent breast surgery were studied. Both groups were similar in demographic, clinical, and surgical varia- bles. Postoperative videolaryngoscopy showed larynx altera- tions in 28% of the thyroidectomized patients, without significant alterations in the control group. There were subjective voice changes in 29.7% of the patients without vocal fold immobility after thyroid surgery and no statistically significant changes after breast surgery. Acoustic analysis showed significant increased values in the voice turbulence index (VTI) parameter in both groups, although higher in the thyroid one. In the VHI assess- ment, voice complaints were more frequently registered in the thyroid group rather than in the control group. Conclusions. Voice alterations are frequent after thyroidec- tomy even with preserved vocal fold mobility. Such alterations were more frequently detected in that group than in patients who underwent breast surgery. Orotracheal intubation is just one of the multiple factors involved.

Radiation therapy and radiochemotherapy protocols can cause swallowing difficulties.To evaluate swallowing in patients undergoing radiation therapy and radiochemotherapy protocol only for the treatment of laryngeal tumors.A prospective study of 20 patients, with a mean age of 62 years, at the end of oncological therapy. Six patients (30%) underwent radiation therapy, and 14 patients (70%) underwent combined therapy. The mean time between treatment and an evaluation of swallowing was 8.5 months. Videofluoroscopy was done to assess the preparatory, oral and pharyngeal phases of swallowing.All patients had only an oral diet. Normal swallowing was present in only 25% of patients. The swallowing videofluoroscopic examination identified the following changes: bolus formation (85%), bolus ejection (60%), oral cavity stasis (55%), changes in the onset of the pharyngeal phase (100%), decreased laryngeal elevation (65%), and hypopharyngeal stasis (80%). Laryngeal penetration was observed in 25% of the cases; 40% presented tracheal aspiration. The grade of penetration/aspiration was mild in 60% of cases. Aspiration was silent in 35% of patients. Although 75% of patients had dysphagia, only 25% complained of swallowing difficulties.Patients with laryngeal cancer that underwent radiation therapy/combined treatment can present changes in all swallowing phases, or may be asymptomatic.

We conducted a prospective study of 11 patients with laryngeal cancer who underwent supracricoid laryngectomy with cricohyoidoepiglottopexy. Our goal was to evaluate their postoperative voice and swallowing function and to ascertain the impact that surgery had on patient-perceived quality of life. Postoperative assessments were made by auditory perception analyses, objective voice analyses, the Voice Handicap Index questionnaire, the Quality of Life in Swallowing Disorders questionnaire, and videofluoroscopy. Following surgery, 8 patients experienced severe dysphonia and 3 experienced moderate dysphonia. Also, 5 patients experienced mild to severe dysphagia whereas 6 patients experienced normal or near-normal swallowing function. Postoperative acoustic measurements were higher than expected, and spectrographic evaluation revealed the presence of high-grade noise without predominant concentration over the spectrum. Some association with the grade of dysphonia and self-perception of voice handicap was observed. With regard to swallowing, 5 patients (45.5%) showed a decrease in laryngeal remnant elevation and a slight or moderate degree of stasis in the oropharynx. Overall, patients reported good quality of life regarding both voice and swallowing. No relationship between the functional swallowing and the number of preserved arytenoid cartilages was observed.

Dysphagia can be a consequence of total laryngectomy even in the absence of symptoms and it could indeed directly or indirectly compromise quality of life. AIM: To evaluate the characteristics of swallowing after total laryngectomy and pharyngolaryngectomy with pharyngeal T closure, correlating them with the Quality of Life in Swallowing Disorders questionnaire. METHODS: A prospective evaluation was performed in 28 patients; fifteen undergoing total laryngectomy and thirteen undergoing total pharyngolaryngectomy. Swallowing was evaluated through videofluoroscopy regarding the preparatory, oral and pharyngeal phases of swallowing, and the quality of life related to swallowing questionnaire was employed to measure quality of life. RESULTS: Anatomical and functional changes were observed under videofluoroscopic evaluation. Dysphagia was diagnosed in 18 patients (64.3%), being mild in 66.6% and moderate/severe in 33.3%. The questionnaire indicated good quality of life in almost all scales. Complaints of dysphagia were associated to the burden (p=0.036) and mental health scale (p=0.031). The questionnaire indicated impact on the mental health scale for patients with severe dysphagia (p=0.012). CONCLUSIONS: High incidence of dysphagia was observed in some quality of life assessments, especially of mild degree. A disfagia pode ser uma das consequências após a laringectomia total mesmo na ausência de sintomas e comprometer direta ou indiretamente a qualidade vida. OBJETIVO: Avaliar as características da deglutição após a laringectomia total e faringolaringectomia com fechamento em T e correlacionar com o questionário Quality of Life in Swallowing Disorders. MATERIAL E MÉTODO: Estudo prospectivo através da avaliação de 28 pacientes, quinze submetidos à laringectomia total e treze à faringolaringectomia. A deglutição foi avaliada através da videofluoroscopia em relação às fases preparatória, oral e faríngea e o questionário de qualidade de vida relacionada à deglutição foi aplicado para mensurar a qualidade de vida. RESULTADOS: Na avaliação videofluoroscópica foram observadas alterações anatômicas e funcionais. A disfagia foi diagnosticada em 18 (64,3%) dos pacientes, sendo 66,6% de grau discreto e 33,3% de grau moderado/severo. O questionário indicou boa qualidade de vida em quase todas as escalas. As queixas de deglutição apresentaram associação com o questionário nas escalas fardo (p=0,036) e saúde mental (p=0,031). O questionário indicou impacto na escala saúde mental para os pacientes com disfagia de grau severo (p=0,012). CONCLUSÃO: Observamos grande incidência de disfagia de grau predominantemente discreto com repercussão em algumas escalas da qualidade de vida.

Background The main goals of larynx preservation protocols are preservation of a functional larynx with intact voice and maintenance of normal deglutition. However, few studies have addressed functional outcomes. Objectives To evaluate voice and swallowing in patients enrolled in a larynx preservation protocol. Design and Setting Acoustic analysis of 15 patients and videofluoroscopic evaluation of 14 patients who underwent chemoradiotherapy in an attempt to preserve the larynx. Patients Forty-three patients with larynx or hypopharynx squamous cell carcinomas were treated with weekly paclitaxel (30 mg/m 2 ) and cisplatin (20 mg/m 2 ) concurrent to radiotherapy (180-rad/d fraction [1.8 Gy] to 7040 rad [70.4 Gy]). Voice was analyzed perceptually and acoustically in 15 patients. Videofluoroscopic evaluation of swallowing was performed in 14 patients, focusing on oropharyngeal motility disorders, stasis, laryngeal penetration, aspiration, and dysphagia severity. Results Vocal analysis produced normal results in 1 patient, mild dysphonia in 4, moderate dysphonia in 6, and severe dysphonia in 4. The mean fundamental frequency for acoustic analysis was 131.4 Hz for men and 109.8 Hz for women. Acoustic measures of perturbation and noise were above the reference limits, indicating changes in the voice signal. Swallowing analysis showed inefficient bolus preparation in 13 patients and changes in the bolus propulsion in 12. Stasis was observed in all areas of the oropharynx. Five patients had reduction in laryngeal elevation, and 12 had stasis in the hypopharynx. Five patients presented with silent aspiration. We detected functional swallowing in 3 patients, mild dysphagia in 7, mild or moderate dysphagia in 2, and severe dysphagia in 2. Conclusions Laryngeal preservation resulted in voice and swallowing abnormalities, but they tend to be mild to moderate, allowing intelligible communication and efficient swallowing in most patients.

Background The swallowing deficits that result from oral or oropharyngeal resections vary considerably depending on the site, extension of the resection, and type of reconstruction. Most patients will experience some degree of dysphagia despite the reconstructive effort. Furthermore, a glossectomy is frequently associated with voice and speech difficulties. Objectives To characterize swallowing in patients who underwent a glossectomy and to define the limits and the compensatory movements using video fluoroscopic analysis. Design and Setting Video fluoroscopic evaluation of 15 patients who underwent glossectomies at the Centro de Tratamento e Pesquisa Hospital do Câncer A. C. Camargo, Sao Paulo, Brazil. Patients We examined 15 patients: 5 who underwent a partial glossectomy, 2 who underwent a subtotal glossectomy, and 8 who underwent a total glossectomy with laryngeal preservation and reconstruction with myocutaneous flaps (9 pectoralis major flaps and 1 latissimus dorsi flap). The 15 patients were enrolled in a program that included voice, speech, and swallowing rehabilitation. Results All patients who underwent a partial glossectomy had difficulties with formation and anteroposterior propulsion of the bolus in the oral cavity and an increase in oral transit time, which was more evident with materials of thicker consistencies. All patients who underwent a total or subtotal glossectomy with laryngeal preservation had an increase in oral transit time and stasis of food in the oral cavity, the pharynx, and the superior esophageal sphincter. Of the 15 patients, 2 had moderate and asymptomatic aspiration. These 2 patients had swallowing compensations, such as increased buccal, mandibular, pharyngeal, and laryngeal activity and voluntary protection of the larynx during swallowing. Conclusions This study demonstrates the effectiveness of swallowing in patients who were enrolled in voice, speech, and swallowing rehabilitation after undergoing a partial or total glossectomy. An increase in oral transit time was detected in all patients. Only 2 of the 10 patients who underwent a total glossectomy had persistent asymptomatic aspiration.
