Purpose Laryngeal sensory neuropathy (LSN) is caused by a disorder of the superior laryngeal nerve or the recurrent laryngeal nerve. A diagnosis of LSN should include laryngeal electromyography (LEMG) and laryngovideostroboscopy (LVS). The aim of this study was to characterize the physical and subjective symptoms of neuropathy in patients diagnosed with LSN following COVID-19. Material and methods Since the beginning of the COVID-19 pandemic, 6 patients who had recovered from the disease presented to us with LSN symptoms. All patients underwent laryngological and phoniatric examination, objective and subjective voice assessment, and LEMG. Results The most common LSN symptom reported by patients was periodic hoarseness of varying severity. Other common symptoms were the sensation of a foreign body in the throat and voice fatigue. Endoscopy often showed functional abnormalities. The LSN patients could be characterized by LEMG recordings, and all showed abnormal activity of the cricothyroid (CT) muscle. The degree of EMG changes in the CT correlated moderately with the severity of dysphonia. Conclusions Sensory neuropathy of the larynx may be a long-lasting complication of SARS-COV-2 infection. The severity of EMG neuropathic changes in the CT muscle broadly corresponds to the severity of dysphonia.

The relation between the autonomic nervous system (ANS) and muscles of the vocal tract is of particular importance when considering the pathomechanism of a functional voice disorder.The aim of this study was to record electrophysiological indicators from the ANS as well as the tone of the external laryngeal muscle and test whether together they could point to an enhanced risk of primary functional voice disorder.The study material consisted of 81 people, 27 of whom were professional opera singers. None reported any voice complaints. The research comprised ENT and phoniatric examination, superficial electromyography (SEMG), and recording of physiological indicators (pulse rate, skin resistance).All subjects had a clear voice with no sign of vocal disability. Endoscopy revealed laryngeal hyperfunction in 26 people. SEMG revealed that the 26 had increased external laryngeal muscle tone during phonation, and this finding correlated with a change in certain electrophysiological indicators HRV, BVP, EDA.We conclude that anomalies in electrophysiological parameters in individuals with subclinical symptoms of functional voice disorder may be at risk of developing fully symptomatic hyperfunctional dysphonia in the future. Vocal training, which differentiates singers and non-singers, is known to have an effect on subclinical hyperfunctional dysphonia.By measuring indicators of hyperfunctional dysphonia, it may be possible to take remedial action before symptomatic dysphonia develops.

Purpose In most cases, tinnitus co-exists with hearing loss, suggesting that poorer speech understanding is simply due to a lack of acoustic information reaching the central nervous system (CNS). However, it also happens that patients with tinnitus who have normal hearing also report problems with speech understanding, and it is possible to suppose that tinnitus is to blame for difficulties in perceptual processing of auditory information. The purpose of the study was to evaluate the auditory processing abilities of normally hearing subjects with and without tinnitus. Methods The study group comprised 97 adults, 54 of whom had normal hearing and chronic tinnitus (the study group) and 43 who had normal hearing and no tinnitus (the control group). The audiological assessment comprised pure-tone audiometry and high-frequency pure-tone audiometry, impedance audiometry, and distortion product oto-acoustic emission assessment. To evaluate possible auditory processing deficits, the Frequency Pattern Test (FPT), Duration Pattern Test (DPT), Dichotic Listening Test (DLT), and Gap Detection Threshold (GDT) tests were performed. Results The tinnitus subjects had significantly lower scores than the controls in the gap detection test (p p Conclusion In normally hearing patients, the presence of tinnitus may be accompanied with auditory processing difficulties.

Purpose The objective was to investigate whether a patient’s preoperative test results can predict the need for future reoperation in unilateral vocal fold paralysis (UVFP). Methods A single-centre retrospective study was performed. The study group consisted of 18 patients with UVFP who had been treated with injection laryngoplasty but who required further treatment and were augmentated again within 36 months. The control group consisted of 33 injected patients who had not required reintervention up to 36 months later. Results Only glottal gap was associated with a relative risk for reinjection. Glottal gap was found to be severe in 77.8% of the patients from the study group compared to 42.4% of the controls, and the difference was statistically significant. The kind of injected material (calcium hydroxylapatite or hyaluronic acid), age, and voice assessment (perceptual, objective, or subjective) did not seem to affect the likelihood of reoperation being needed. There were no between-group statistically significant differences in individual aspects of the GRBAS scale. The global score was slightly higher in the study group, but it did not reach statistical significance (U = 198.5; p = 0.09). A comparison of VHI scores did not yield statistically significant differences between the study and control groups. No significant differences in objective acoustic voice parameters were observed between the groups. Conclusion Only glottal gap occurred to be associated with a relative risk for reinjection. A kind of injected material (CaHA or HA), age, perceptual, objective and subjective voice assessment do not seem to impact the likelihood of reoperation in patients with UVFP.

Partial deafness is a condition characterised by normal hearing thresholds in low frequencies and increased hearing thresholds (nearly deafness) for high frequencies. Typical hearing aids are rather of a very limited use in this condition as they do not improve understanding of speech. Patients with partial deafness can be presently treated with cochlear implants, which had not been used before due to the risk of damage of hearing remains by electrode introduced into cochlea. The purpose of our study was an objective and subjective assessment of voice quality in partial deafness patients before and after cochlear implantation. The subjects in this study were 25 post-lingual, bilaterally partially deaf patients, 13 females and 12 males. The reference group composed of 55 normal hearing individuals (28 females and 27 males). The acoustic analysis was performed with a multidimensional voice analysis MDVP (Multi Dimension Voice Program), and the subjective assessment was done with GRBAS scale. Initial analysis of voice changes in partial deafness patients was performed versus normal hearing individuals, then voice parameters were measured and perceptual voice assessment was done before and 9 months after cochlear implantation. Measurements of acoustic voice parameters in partially deaf patients showed changes in most of frequency, amplitude, noise and subharmonic components versus normal hearing control group. The most significant, statistically important changes were observed in fundamental frequency variation (vF0), absolute jitter (Jita), jitter percent (Jitt), amplitude perturbation quotient (APQ), smoothed amplitude perturbation quotient (sAPQ), relative average perturbation (RAP), peak amplitude variation (vAm), relative amplitude modulation (Shim), percent shimmer (%Shim), pitch perturbation quotient (PPQ), smoothed pitched perturbation quotient (sPPQ), degree of subharmonics (DSH), degree of voiceless (DUV), number of subharmonic segments (NSH), noise-to-harmonic ratio (NHR), voice turbulence index (VTI). All patients in the study group were subjects to cochlear implantation. After 9 months objective and subjective assessment of patients` voices were performed again. Statistically important changes were identified in average fundamental frequency variability (vF0), relative amplitude modulation index (ShdB), noise-to-harmonic ratio (NHR), number of subharmonics NSH, degree of subharmonics (DSH) and the degree of voiceless (DUV). Comparison of the objective voice parameters changes after cochlear implantation with subjective, perceptual voice quality assessments leads to observation, that improvement of subjective voice quality after cochlear implantation takes place parallelly with improvement of certain objective acoustic voice parameters and some correlations exist. We found, that G correlates with vF0 and Shim, R correlates with DSH and NSH, B correlates with NSH and NHR, A correlates with DUV. We did not prove correlation of S with any of the objective parameters in our research group. Our study proved, that acoustic and perceptual features of voice in partially deaf adults are different than in normally hearing people and cochlear implantation in partial deafness patients is an effective tool to improve hearing and leads to improvement of the acoustic structure of the voice.Partial deafness is a condition characterised by normal hearing thresholds in low frequencies and increased hearing thresholds (nearly deafness) for high frequencies.

The surface EMG technique (sEMG) gives valuable assessment of vocal tract as well as diagnosis or outcome assessment in dysphonia. There are very few papers on the use of sEMG in vocal professionalists.The aim of this study was to evaluate the electromyographic characteristics of selected external laryngeal and neck muscles in professional opera singers.The study material consisted of 50 subjects. Twenty-six opera professional singers and 24 healthy non-singers.Each person underwent otolaryngologic and phoniatric examination, laryngeal videostroboscopy, hearing testing, multiparametric acoustic voice analysis (multidimensional voice program) and sEMG of submentalis, cricothyroid and sternocleidomastoid muscles.Statistical analysis of the values of the amplitudes of the submentalis and the cricothyroid muscles showed significant differences between the vocalists and the control group. Moreover, during vowel phonation and glissando, significantly greater differences in the asymmetry of sternocleidomastoid muscles amplitudes were observed in singers compared to the control group. In most subjects, the studied muscles did not show asymmetry during saliva swallowing.Laryngeal muscle function should be assessed during different phonation and non-phonation tasks. Singers have different SEMG characteristics than non-singers. Knowledge of the patient's history and endoscopic studies is needed to interpret EMG recordings.

The purpose of the study was to assess outcomes of injection laryngoplasty (IL) for treating glottal insufficiency in elderly patients with presbyphonia or unilateral vocal fold paralysis (UVFP).A single-center retrospective study was performed. The study group consisted of 34 patients with glottal insufficiency aged between 60 and 82 years who had been treated with injection laryngoplasty. Of them, 16 patients were diagnosed with presbyphonia and 18 with UVFP.After IL, glottal closure improved in both groups. The change was statistically significant in the patients with presbyphonia (marginal homogeneity test MH = 3.80; p 0.001) and in the UVFP patients (MH = 4.04; p 0.001). Voice quality improved after IL and 12 months after surgical intervention remained significantly better compared to before augmentation (MH tests were statistically significant at p 0.05 for R, B, A, and S parameters). In the patients with UVFP, significant improvement was observed in 7 of 12 evaluated parameters (Jitt, RAP, PPQ, Shim, APQ, sAPQ, and NHR) but in the patients with presbyphonia only average fundamental frequency (F0) improved significantly. Comparison of the Voice Handicap Index outcomes before and 12 months after surgery showed improvement of subjectively assessed voice quality in both groups; however, the change was statistically significant only in the UVFP patients.Injection laryngoplasty is a safe and effective treatment method for glottal insufficiency in the elderly. This study shows a significant and clinically relevant improvement to at least12 months, especially in patients with UVFP.

Introduction Coexistence of dysphagia with voice disorders is a topic rarely raised in the literature. Particular attention is paid to the aspect of dysfunction of laryngeal and pharyngeal muscles. Aim The aim of the study was to analyse cases of patients with dysphonia in relation to coexistence of swallowing disorder. Material and method The material of the study included 515 patients hospitalised due to dysphonia in 2018. Patients whose interview indicated swallowing difficulties were subjected to additional diagnosis for dysphagia (FEES, extended speech therapy test, SEMG). R esults: 11.8% of people requiring treatment for voice disorders reported coexistence of swallowing difficulties. Dysphagia was diagnosed in 9.3%. The percentage of respondents diagnosed with swallowing disorder differed depending on the type of underlying disease and was the highest in the group with neurological disorders. Analysis of the correlation between the severity of dysphagia (according to the assessed grade, DHI, EAT-10 results) and the severity of VHI showed a weak correlation between VHI and EAT-10 (p = 0.1), statistically significant correlations (p l 0,05) between the value of VHI and RSI in people with diagnosed neurological disease, between the value of VHI and DHI in people with hyperfunctional dysphonia and the value of VHI and BMI and EAT- 10 in people with chronic laryngitis. Moreover, statistically significant correlations were found between the severity of dysphagia and EAT-10 and DHI (p l 0.05). The speech therapy test indicated the co-existing problem of non-normative swallowing pattern. The electromyographic study showed the largest asymmetries in recording the average and maximum amplitude from masseters. C onclusions: Treatment of patients with voice disorders requires interdisciplinary care. A history of dysphagia in these patients should complement the medical history of voice disorders. The characteristics of swallowing disorders vary depending on the cause of the voice disorder and their co-occurrence affects on average 9.3% of patients. Coexistence of muscle tension dysphagia with voice disorder requires separate diagnostic protocol. Logopaedic procedure ought to be a key element in the interdisciplinary care of patients suffering from muscle tension dysphagia.

ntroduction: The publication describes the characteristics of the glottis in FDs objectified by OQ, measured with VSK and EGG. Aim: The aim of the study was to objectify glottal function in different types of FDs. The scope was to use open quotients gained from various mucosal wave imaging techniques for differential diagnosis of FDs. Material and Method: The study included 204 individuals. In the study, each patient underwent otolaryngological and phoniatric examination. LVS, EGG and VSK were conducted, their results were recorded and stored using an EndoSTROB-DX- -Xion GmbH (Berlin) device with DIVAS software. Results: All patients with FDs had abnormalities in LVS. A statistical analysis showed differences in LVS characteristics according to the type of FD. The mean value of OQVSK was 0.521 in the control group and 0.565 in the study group (P < 0.05). Significant differences were found between patients with hypofunctional – 0.584 and hyperfunctional dysphonia – 0.55. The QOQEGG mean value in patients with FDs was 0.581 and in the control group 0.549 (P < 0.01). There were statistically significant differences between groups of patients with hyper- and hypofunctional dysphonias. Medians amounted to 0.574 and 0.604, respectively. Authors observed different relations of OQ with the type of FD. They decided to introduce a new parameter, illustrating the proportion of QOQEGG/OQVSK. Conclusions: Videostrobokymographic and electroglottographic open quotients differentiate euphony from dysphony. The value of OQVSK and QOQEGG and their proportion varies depending on different types of functional dysphonias. The OQVSK and QOQEGG should be included in the diagnostic algorithm of voice.

lt;bgt;Introduction:lt;/bgt; Patient-reported outcome measures have been used within the otorhinolaryngologic disorders' field for many years to compare patient's perception of the severity of symptoms and the effectiveness of a therapeutic approach. Questionnaires that evaluate dysphagia are relatively complex instruments aimed mostly at patients with neurological or malignant diseases. The ICD-10 classification specifies only one broad term - dysphagia (R13). Introduction of Muscle Tension Dysphagia (MTDg) in 2016 by Kang completed the spectrum of the nomenclature. This dysphagia type is defined as a type of laryngeal muscle tension disorder manifesting primarily as swallowing difficulty with or without any accompanying organic cause, laryngeal hyperresponsiveness and/or nonspecific laryngeal inflammation.lt;brgt;lt;bgt;Aim:lt;/bgt; Since there were no clear diagnostic and therapeutic perspectives on the group of patients with MTDg, the aim of this work was to analyse selected diagnostic tools used for the evaluation of swallowing disorders in the context of finding the most suitable tools for patients with Muscle Tension Dysphagia.lt;brgt;lt;bgt;Material and method:lt;/bgt; The material of the work included 61 patients. Each patient underwent otolaryngologic, phoniatric and speech therapist's examination, Functional Endoscopic Evaluation of Swallowing (FEES) and filled out questionnaires concerning dysphonia and dysphagia symptoms.lt;brgt;lt;bgt;Results:lt;/bgt; The results of the work showed that patients with MTDg were characterised by correct results of FEES examination, prolonged swallowing, features of inappropriate mucous and oropharyngeal muscle function.lt;brgt;lt;bgt;Conclusions:lt;/bgt; The Swallowing Disorder Scale (SDS), developed by the authors, correlated best with the cause of dysphagia. The questionnaire corresponded well with the degree of severity. In the diagnostic process of MTDg one of the key tasks is the differentiation with patients with non-normative swallowing patterns. Apart from specialistic consultations with otolaryngologist and speech therapist, while diagnosing MTDg we recommend using objective (FEES, videofluroscopy, SEMG) and subjective (SDS, DHI, EAT-10 surveys) assessment tools. In our opinion, the inclusion of questionnaires to detect reflux syndromes is also important in the causal treatment of ailments.

Introduction: Voice disorders in children especially in the school-age period comprise a major and challenging medical, social and educational issue. There is a lack of epidemiological data regarding children’s voice in Poland which limits the development of preventive and medical pediatric procedures in our country. Objective: The aim of study was to determine the prevalence of voice disorders in children starting school education in Mazovia. Material and method: The study was a retrospective analysis of survey data from parents of children attending the first grade of primary school. The survey consists of five questions describing the voice. A statistical analysis of 7891 questionnaires was carried out. Results: Analysis of the survey showed a prevalence of dysphonia in 12.8% children aged 7 starting primary school. In this study, voice disorders were observed more often in boys (14.6%) than girls (10.8%). The authors presented the correlation between voice disorders and the expression of emotions. Conclusions: Studies have shown that the percentage of children with voice disorders is significant in our country. The survey regarding voice in school children in Mazovia shows preliminary results of voice disorders in the pediatric population in Poland.

Introduction The modern standard of voice diagnostics in both the adult and pediatric populations is based on perceptual, acoustic and videolaryngoscopic assessment, as well as self-assessment of voice quality. Currently, only two tools for assessing the voice in the pediatric population were translated into Polish: pVHI and its abbreviated version - cVHI (Children Voice Handicap Index). Thanks to the use of pVHI, the therapist and the patient, as well as his family and relatives, become aware of what functional zones are disturbed as a result of voice problems. Aim The aim of the study was to analyze various methods of assessing children's voice, including the pVHI voice disability questionnaire in children with various voice disorders. In addition, the authors wanted to develop a classification of the degree of disability of children's voice expressed by the sum of points obtained in pVHI. Material and method The study included a group of 89 children aged 5-12. Each child underwent a standard otolaryngological and phoniatric examination procedure with hearing assessment and fiberoscopic laryngeal evaluation. The voice of the dysphonic children was assessed with a spectrogram and the GRBAS scale. The children's guardians completed the Pediatric Voice Handicap Index (pVHI). Results Polish children without voice disorders obtained an average of 1.9 points as a total result of the pVHI questionnaire. The results of the questionnaire obtained from children with voice disorders were on average 24.7 (SD 13.9). Total and individual domain scores were significantly higher in children with dysphonia than in asymptomatic children. Children with voice disorders were rated an average of 1.95 (SD 0.6) degree of hoarseness in Yanagihara's scale, and obtained an average overall score of 4.8 on the GRBAS scale (SD 2). A common upward trend in all types of evaluation is evident, along with an increase in the handicap expressed in pVHI score. Statistical analysis showed significant dependence between the overall pVHI score and other voice rating indicators. The result correlated to a moderate degree with the sum of points obtained from GRBAS and the severity of hoarseness assessed subjectively (G) and objectively according to Yanagihara's scale. In addition, weak correlations of the functional part of the questionnaire with the presence of learning problems, and the emotional part with the presence of problems with socialization were noticed. Analyzing the results of the questionnaire depending on the GRBAS results and the Yanagihara scale, a better fit of the exponential trend line than the linear one was observed. The point of inflection of the exponential curve, and thus a significant deterioration in voice assessment indicators, was observed in children who obtained over 32 points, which is 33% of the maximum value that can be obtained from the questionnaire. Conclusions A new voice assessment tool for the pediatric population has been developed that complements the diagnostic facilities of the otolaryngologist, phoniatrician and speech therapist. Adaptation of the Polish version of the Voice Handicap Index (pVHI) allows the introduction of a new diagnostic indicator into medical and speech therapy practice. The pVHI questionnaire result differentiates children with voice and speech disorders from healthy children. The analysis of children's voice using various methods allows the clinician to further characterize the disturbance of voice quality. It is possible to assess the scale of the severity and type of problem, as well as the spheres of life it concerns most. There is a correlation between the severity of voice disorders and the severity of voice disability expressed in the pVHI question.

Clinical experience shows that children with functional dysphonia often present disorders that are associated with abnormal auditory and emotional development. These children also struggle with voice therapy, perhaps because of difficulties with auditory control during speech. It has been hypothesized that difficulties in auditory processing in children may be an important factor in the pathogenesis of childhood dysphonia.The study aimed to assess selected auditory functions in children with hyperfunctional dysphonia.The study group consisted of 331 children aged from 7 to 12 years suffering from hyperfunctional dysphonia. The control group consisted of 213 children aged 7-12 years. All patients underwent ENT and phoniatric examination. All children underwent two standardized psychoacoustic tests: the Frequency Pattern Test (FPT) and the Duration Pattern Test (DPT).In the examined material, 223 children had edematous vocal fold nodules. The largest statistically significant differences were seen in the acoustic parameters describing relative frequency changes. FPT and DPT showed statistically significant differences in children with hyperfunctional dysphonia compared to the control group. At all ages the percentage of correctly identified tone sequences was significantly lower in children with dysphonia.Children with hyperfunctional dysphonia have difficulties in judging the pitch and duration of auditory stimuli. Difficulties in auditory processing appear to be important in the pathomechanism of functional voice disorders. Impaired hearing processes in children with hyperfunctional dysphonia can make it difficult to obtain positive and lasting effects from voice therapy.

Introduction: Hyperfunctional dysfunction is one of the most common functional dysphonia, cha-racterized by voice insufficiency with excessive tightening of the muscles inside and outside the larynx during phonation. To make the treatment process more effective, new ways of rehabilitation are constantly being sought and developed. The aim of this work is to evaluate the effectiveness of laryngotaping - an innovative method of taping around the larynx and neck muscles. Material and method: 10 patients with diagnosed hyperfunctional dysphonia participated in the study. Using the kinesiotaping principles, for 7 days, the suprahyoid and infrahyoid muscles, ster-nocleidomastoid muscles as well as the thyroid cartilage were taped. Before and after the therapy, the patients completed the VHI voice self-evaluation questionnaire. The evaluation of the larynx according to the L. Mathienson scale was also assessed palpation. Results: Analyzing the results of the VHI questionnaire and evaluation of palpation evaluation of the larynx before and after the therapy, statistically significant differences were observed. The results on average decreased by half, which is the desired effect of therapy. Discussion: The results confirm the positive impact of kinesiotaping around the larynx. However, more research is needed on a larger group of patients to fully evaluate the therapeutic effect. Conclusions: 1. Laryngotaping is an effective way to normalize muscle tone, and thus to improve the quality of the voice. 2. The presented studies require continuation, however, positive reception of the introduced therapy by patients encourages further research on a larger group of patients.

Introduction Electroglottography (EGG) is the most commonly used method of indirect visual examination of vocal fold vibration. Aim The study was conducted with an aim of assessing EGG quasi open quotient (QOQEGG) in different functional dysphonias to develop a differential diagnosis. The second aim was to check the influence of articulation on QOQEGG values. Material and methods There were 20 people without voice problems, 20 patients with hypofunctional dysphonia and 20 patients with hyperfunctional dysphonia included in the study. Electroglottography was recorded during comfortable sustained phonation of [a], [e], [i], [o], [u]. Results There were no statistically significant differences in QOQEGG observed during phonation of different vowels in the control group and patients with hyperfunctional dysphonia. In patients with hypofunctional dysphonia, significantly higher values of QOQEGG were observed during [a] and [e]. Both in the control and in studied groups vowel [i] was vocalized significantly quieter. Conclusions To conclude, EGG can be useful in differential diagnosis of functional dysphonia. QOQEGG is a parameter differentiating hypofunctional dysphonia from hyperfunctional dysphonia. Dissimilarities in articulation of different vowels in patients with various types of dysphonia influence values of QOQEGG. EGG study protocol in cases of functional dysphonia should include a comparison of [a], [e], [i] vowels.

Introduction Laryngeal paralysis deteriorates all laryngeal functions. Therefore the therapeutic process must include restoration of respiratory, defensive and vocal function. Selection of a proper rehabilitation path plays a key role. Appropriate research protocol that includes objective methods of voice evaluation is an important element of monitoring the return of vocal efficiency. Voice efficiency is important for the patient particularly due to psychological and social reasons. Aim The aim of the study was the assessment of short-term functional voice therapy (FVT) in patients with unilateral paralysis of the larynx with the usage of objective parameters describing the glottis and voice quality. Material and Method During the last 10 years 355 patients with laryngeal paralysis were hospitalized in the Audiology and Phoniatrics Clinic due to dysphonia. All patients undergone 5-day FVT. From 2015 we unified diagnostic protocol measuring parameters obtained from videostrobokymography (VSK), electroglottography (EGG), perceptual and acoustic voice analysis before and after 5 day hospitalization. Results After FVT patients improved voice quality and glottal compensation. The majority of patients achieved a statistically significant improvement in the VSK, EGG, MDVP and perceptual analysis. Group of patients with unsatisfactory voice improvement after therapy required a prolonged rehabilitation or has been qualified for laryngeal microsurgery. Potential factors that could have cause insufficient effects of FVT were analysed. Conclusions The complexity of voice rehabilitation is crucial for the success of therapy. Interdisciplinary therapeutic team plays a significant role during voice rehabilitation in patients with vocal fold paralysis.

Purpose The objective was to evaluate the long-term voice outcomes in pa-tients with unilateral vocal fold paralysis treated with injection laryngoplasty using either cal-cium hydroxylapatite (CaHA) or hyaluronic acid (HA). Methods A single-centre retrospective study was performed. There were 75 patients with dysphonia due to unilateral vocal fold paralysis: injected with CaHA or injected with HA. We analysed Voice Handicap Index-30 (VHI), videostroboscopic images, auditory-perceptual (GRBAS), and acoustic measures (MDVP) in 6, 12, and 24 months after augmentation. Results The mean change in VHI 24 months after augmentation was 29.14 in the CaHA group, and 22.88 in the HA group. There was an improvement of glottal gap 6, 12, and 24 months after augmentation in both groups. The GRBAS parameters were similar in both groups throughout the whole period. The MDVP pa-rameters decreased 6 and 12 months after augmentation and were similar in both groups. There were 4 patients augmented with CaHA (12.5%) who needed reintervention within 2 years of surgery and another 4 (9.3%) augmented with HA. Conclusion This study demonstrates that there are no long-term differences in voice outcomes or number of reaugmentations for injection laryn-goplasty with CaHA compared to HA.

RSI and RFS questionnaires are a basic and common method used for initial diagnosis of laryngopharyngeal reflux (LPR). However, they only measure symptoms which may or may not be concurrent with LPR. The severity of these symptoms is assessed either by the patients themselves (with the use of the Reflux Symptoms Index -RSI) or by the doctor specialising in the field (with the use of the Reflux Finding Score - RFS). Therefore, the findings of the questionnaire may to a large extent depend on the study population - its demographic and cultural characteristics; the extent to which the medical terms used in the questionnaires are understood; and on the linguistic aspects and translation choices. As for the Polish language versions of these questionnaires, there is no reliable analysis of their consistency and if they reach the assumed goal. The studies we have conducted on a group of 84 patients show that we encounter at least one of the above-mentioned problems. Therefore, to make the questionnaires reliable and useful for diagnosis, it is necessary to conduct a formal validation of their translation and to conduct studies on reference groups.

Introduction: Upper respiratory tract infections are common childhood diseases. Children are more susceptible to middle ear infections because their Eustachian tube is short, straight and wide. As a consequence of these inflammatory changes while impaired patency of the Eustachian tube often arises conductive hearing. Objective: The aim of this study was to Assessment effectiveness of treatment Eustachian tube dysfunction using inhaler AMSA. Material and Methods: The study group comprised 30 patients. Same was in the control group. All patients reported conductive hearing loss. Test group was treated as an inhaler AMSA. The control group was treated pharmacologically. Patients were examined with the use of pure-tone audiometry, and impedance at baseline, after one week and four weeks. Results: Statistical analysis showed improvement in the studied parameters in patients treated with inhaler AMSA in a much shorter time than patients treated with pharmacotherapy.

Introduction: Distorted processing of auditory information has a negative impact on the child’s cognitive development. There are only a few studies conducted by Polish researchers determining the normative values of psychoacoustic tests in auditory processing disorders. They are inconsistent due to different methodologies and different research protocols. Objective: The aim of the work was to determine the reference values of selected psychoacoustic tests for the population of Polish children between 7 and 12 years of age. Material and method: The study group consisted of 213 healthy children from 7 to 12 years of age. The condition for including the child in the study was an intellectual norm, proper sound sensitivity, proper development of children’s voice and speech. All children underwent two auditory temporal processing tests. The diagnostic procedure used a standardized Frequency Pattern Test (FPT) and Duration Pattern Test (DPT). The tests were carried out in accordance with the authors' recommendations, using the original versions available on the CD for 60 dB SL intensity, simultaneously for the right and left ear. Results: The reference values for FPT and DPT tests were determined at various age ranges in children aged 7-12. It has been shown that auditory functions change with age and development of the child. Reference values including age, language, cultural and educational differences were prepared. Conclusions: The development of reference values for individual tests for the Polish children population is a key element in the reliable diagnosis of auditory processing.

Objectives The aim of this study was to assess the usefulness of 24-h pharyngeal pH monitoring in the diagnosis of laryngopharyngeal reflux (LPR) in children with voice disorders. Methods The study was conducted on 68 children aged 3–18 years old. In all cases, pH monitoring was successful; no child removed the probe from the nasal cavity or reported discomfort or other complaints. The following definitions were adopted: LPR in the upright position if Ryan Score upright >9.41; LPR in the supine position if there was at least one supine episode below pH 5.0 (equal to a Ryan Score supine >2.91). Results In 43 children (63%), vocal fold edema was strongly related to recorded reflux episodes, especially in the upright position. In 18 children (26%), vocal nodules were observed, but their occurrence did not significantly affect the Ryan Score, either upright or supine. The selected potential LPR markers were significantly correlated to all the pH monitoring variables and individual elements on the Reflux Symptoms Index and the Reflux Finding Score questionnaire. Conclusion Our findings indicate that, together with vocal fold edema, laryngeal edema and posterior commissure mucosal hypertrophy are important determinants of paediatric LPR. In fact, if LPR is suspected in a child, 24-h pharyngeal pH monitoring appears to be a valuable and welltolerated diagnostic tool. Vocal fold edema observed in laryngeal endoscopy can be considered a probable sign of LPR. The Reflux Finding Score appears to be helpful in diagnosing LPR in children, especially if a cut-off value of 4/5 is adopted.

The work assessed the clinical utility of open quotients measured during laryngovideostroboscopy and electroglottography. Values of the parameters were analyzed according to clinical diagnosis. An algorithm based on direct and indirect mucosal wave measurement is presented, which allows for differentiation of voice disorders. The method developed for the objectification of glottal functions in various voice pathologies is characterized by high sensitivity and specificity.

The proper course of speech development heavily influences the cognitive and personal development of children. It is a condition for achieving preschool and school successes – it facilitates socializing and expressing feelings and needs. Impairment of language and its development in children represents a major diagnostic and therapeutic challenge for physicians and therapists. Early diagnosis of coexisting deficits and starting the therapy influence the therapeutic success. One of the basic diagnostic tests for children suffering from specific language impairment (SLI) is audiometry, thus far referred to as a hearing test. Auditory processing is just as important as a proper hearing threshold. Therefore, diagnosis of central auditory disorder may be a valuable supplementation of diagnosis of language impairment. Early diagnosis and implementation of appropriate treatment may contribute to an effective language therapy.

UNLABELLED Sulcus vocalis is one of the most difficult to treat benign vocal fold pathologies. Ford distinguished three types of sulci: I- superficial, II- vergeture and III- true sulcus vocalis. The aim of the study was to assess the results of surgical treatment in patients with sulcus vocalis. Material of the study consisted of 24 patients with type II (16 subjects) and type III sulcus (8 subjects). METHODS Videostroboscopy, perceptual voice assessment and objective acoustic voice analysis were performed before surgery and at 8 months of follow-up. All patients underwent surgical treatment as well as pre- and postsurgical voice therapy. RESULTS Postsurgical stroboscopic examination showed statistically significant differences in symmetry and regularity of vibrations. Subjective perceptual voice assessment showed improvement in the grade of voice hoarseness, roughness, breathiness and strain. Objective voice analysis showed statistically significant difference only in jita parameter, in contrast to other examined parameters--although their values decreased after surgery, the change was not statistically significant. CONCLUSIONS Surgical treatment of sulcus should be considered in patients with severe voice problems; however, the end results are not always entirely satisfactory.

Specific Language Impairment (SLI) affects about 7-15 % of children of school age and according to the currently accepted diagnostic criteria, it is presumed that these children do not suffer from hearing impairment. The goal of this work was to assess anomalies of central auditory processes in a group of children diagnosed with specific language impairment. Material consisted of 200 children aged 7-10 years (100 children in the study group and 100 hundred in the control group). Selected psychoacoustic tests (Frequency Pattern Test - FPT, Duration Pattern Test - DPT, Dichotic Digit Test - DDT, Time Compressed Sentence Test - CST, Gap Detection Test - GDT) were performed in all children. Results were subject to statistical analysis. It was observed that mean results obtained in individual age groups in the study group are significantly lower than in the control group. Based on the conducted studies we may conclude that children with SLI suffer from disorders of some higher auditory functions, which substantiates the diagnosis of hearing disorders according to the AHSA (American Hearing and Speech Association) guidelines. Use of sound-based, not verbal tests, eliminates the probability that observed problems with perception involve only perception of speech, therefore do not signify central hearing disorders, but problems with understanding of speech. Lack of literature data on the significance of FPT, DPT, DDT, CST and GDT tests in children with specific language impairment precludes comparison of acquired results and makes them unique.

Purpose This is a retrospective study to evaluate the results of surgical treatment of patients with pathological sulcus vocalis. Methods Thirty-six patients with pathological sulcus underwent surgery and in 33 cases were performed additional injection laryngoplasty. The pre- and postoperative evaluation of patients included the GRBAS scale, stroboscopic, and objective acoustic voice assessment. The Voice Handicap Index questionnaire (VHI-30) was also used and the scores were obtained from 33 patients. Results The stroboscopic evaluation showed significant improvement of amplitude, mucosal wave, and glottal closure after treatment (p

According to the severity, Reinke's edema (RE) of the vocal folds can be divided into three stages as classified by Yonekawa. We evaluated open and closed quotients of vocal folds vibratory cycles using Videostrobokymography (VSK) in a cohort of patients with RE. Parameters were measured from the anterior, medial and posterior third of the vocal folds. Mean values from RE group were OQ (0.44; 0.46; 0.52); CQ (0.56; 0.54; 0.48). Results from the whole glottis OQ and CQ in RE were: OQ = 0.48 and CQ = 0.52. Significant differences were found for OQ and CQ mean values as well as values measured from each third of the glottis between the control group and patients with RE. In the first Yonekawa group no statistically significant differences were found compared to the control group, but there were significant differences in the remaining two groups. The correlation between the stage of edema on the Yonekawa classification and the mean values of OQ and CQ was 70%.

Aim Tornwald's cyst is a recess in the midline of the nasopharynx, which is produced by persistent notochord remnants. The aim of the study was to present difficulties in diagnostic procedures in patients with Tornwald's cyst suspicion. Material and method Authors present 2 cases of patients being treated for Tornwald's cyst in the Audiology and Phoniatrics Clinic of Institute of Physiology and Pathology of Hearing in Warsaw. Results Discussed patients complained fullness in ears, hearing disorders, tinnitus, dysphagia, occipital headaches and balance problem. Both patients underwent ENT examination with endoscopic examination of nasopharynx and hearing assessment tests(pure tone audiometry, impedance audiometry). Magnetic resonance imaging and computer tomography were also performed. Surgery of nasopharyngeal cyst and tympanotomy with drainage of middle ear were performed in one patient. Second patient was treated with TRT therapy for her tinnitus. Conclusion Tornwald's cyst should be remembered as an uncommon cause of hearing problems, tinnitus, fullness in ears, dysphagia, occipital headaches and balance problem. Magnetic resonance imaging seems to be the most specific method in Tornwald's cyst diagnosis.

Summary Objectives There is a necessity to include objective methods to the study protocol of voice. Such procedure will help not only in diagnosing and monitoring the course of treatment, but also in comparing the results of studies between research centers. Methods Vocal fold mucosal wave characteristics of 70 healthy people were made using videostrobokymographic open quotient (VSK OQ ) and electroglottographic quasi-open quotient (EGG QOQ ). Results Statistically significant differences were achieved regarding gender for the averaged values of VSK OQ as well as for values calculated from the posterior part of the vocal folds. A statistically significant correlation between the value of VSK OQ and age was observed for the posterior part of the glottis. Differences between gender and the value of EGG QOQ were observed. No statistically significant correlation between EGG QOQ and age was obtained. Conclusions VSK OQ and EGG QOQ are parameters characterizing glottal function in a coherent manner. These parameters can be included easily in phoniatric examination and help to objectify glottal function.

Background Glottal incompetence is one of the most common contributing factors in patients who suffer from dysphonia. One of the different treatment approaches is injection laryngoplasty. The aim of the study was to assess the quality of voice in patients who were treated with hyaluronic acid injection into the vocal fold in the long-term follow-up. Material and methods The material included 39 patients with dysphonia who were referred for injection augmentation. The studied group included patients with presbyphonia, scar, sulcus, unilateral vocal fold paralysis and with atrophy of the vocal fold. Preoperative and postoperative examination was based on laryngovideostroboscopy. Patients' voice was assessed using the subjective GRBAS scale, and objective evaluation provided by Multidimensional Voice Program (MDVP) was applied. All the patients underwent injection laryngoplasty with hyaluronic acid into the vocal folds. Follow-up examinations were conducted 6, 12 and 24 months postoperatively. Results Perceptual voice quality assessed with the GRBAS scale was improved and the results were stable in the long-term follow-up periods. MDVP showed a significant statistical improvement within the group of frequency, amplitude and noise parameters. The differences in value between follow-up periods were not statistically significant. Conclusions Acoustic analysis of voice is a reliable method for objective assessment of voice quality after applied treatment. Injection of the hyaluronic acid into the vocal fold improves the quality of voice in patients suffering from glottic insufficiency.

Summary Introduction Thanks to videostrobokymography the vocal fold vibration from particular area of glottal chink, can be assessed in an objective way. Aim Evaluation of objective parameters of vocal fold vibration with the usage of videostrobokymography in patients with different voice disorders. Material and Methods Material of the study included patients treated in the Institute of Physiology and Pathology of Hearing, Audiology and Phoniatrics Clinic. 82 patients with normal voices, vocal fold nodules, polyps, Reinke edema, vocal cord paralysis and functional dysphonia were enrolled into the study. Open Quotient (OQ) from frontal, middle and dorsal third of vocal folds were measured. T-Student test was used for statistical analysis. Results The study revealed differences of OQ in control group and patients with organic or functional dysphonia. Differences in parameters were calculated for each vocal fold region. The mean value of OQ in control group was 0.56 (frontal third), 0.55 (middle third), 0.597 (dorsal third). Statistical significant differences of OQ calculated from separate glottal chink areas, were observed in Reinke edema (from frontal and middle third) and vocal cord paralysis (from frontal third). Conclusions Videostrobokymography is an useful complement to classical stroboscopy. Objective parameters enables the objectification of vibratory activities. Videostrobokymography is helpful in differential diagnosis of voice disorders.

Introduction: Method of vocal folds implantation with allogenic materials has been applied in medical centre all over the world for over 30 years. This voice improving method is usually applied in several indications such as: presbyphonia, vocal folds paralysis, glottis insufficiency, vocal fold scars or sulcus vocalis. All of these illnesses prevent the patients to obtain full glottis closure and produce good quality voice. Aim: To assess quality of voice after implantation of hyaluronic acid to the vocal folds. Material: Consisted of 15 patients, who underwent surgical implantation of hyaluronic acid to the vocal folds. 10 patients had the procedure performed on both sides of the larynx, this group included 6 patients with vocal insufficiency of the glottis, 2 with scars and atrophy of the vocal folds and 2 with presbyphonia. In 5 cases the hyaluronic acid was applied on one side of the larynx. The group included 4 patients with vocal folds paralysis and one person with single sided scars and atrophy of the vocal fold. Method: Each patient was examined with videostroboscopy and underwent objective and subjective assessment of voice. Hyaluronic acid was injected surgically under Jet Ventilation general anesthesia. In two cases during the procedure scars were removed from the vocal folds. All patients after hyaluronic acid augmentation took part in the rehabilitation program that included series of voice emission exercises before operation and up to 3 months after the procedure. Examination was performed 1, 3 and 6 months after injection. Results: In all cases improvement of quality of voice was obtained which was stated by a physician and the patients subjectively. Improvement of harmonic voice structure was confirmed by spectrographic record. Acoustic examinations revealed that the improvement was obtained within parameters describing frequency, amplitude disturbance and noise existence. Conclusions: Injection of the hyaluronic acid to the vocal folds improves functional phonation and quality of voice in cases of patients with glottis insufficiency. Injection of the hyaluronic acid to the vocal folds is an efficient method improving quality of voice and can be safe alternative for no surgery method in rehabilitation of voice. This method is a simply, effective and quickly to improve of voice disorders. © 2011 Polish Otolaryngology Society.

Summary Aim To assess effectiveness of the auditory training in children with dyslalia and central auditory processing disorders. Material and Method Material consisted of 50 children aged 7–9-years-old. Children with articulation disorders stayed under long-term speech therapy care in the Auditory and Phoniatrics Clinic. All children were examined by a laryngologist and a phoniatrician. Assessment included tonal and impedance audiometry and speech therapists’ and psychologist's consultations. Additionally, a set of electrophysiological examinations was performed – registration of N2, P2, N2, P2, P300 waves and psychoacoustic test of central auditory functions: FPT – frequency pattern test. Next children took part in the regular auditory training and attended speech therapy. Speech assessment followed treatment and therapy, again psychoacoustic tests were performed and P300 cortical potentials were recorded. After that statistical analyses were performed. Results Analyses revealed that application of auditory training in patients with dyslalia and other central auditory disorders is very efficient. Conclusions Auditory training may be a very efficient therapy supporting speech therapy in children suffering from dyslalia coexisting with articulation and central auditory disorders and in children with educational problems of audiogenic origin.

Aim: The main goal of the present study was to assess the feasibility of using evoked stapedius reflex (eSR) and evoked compound action potential (eCAP) thresholds to create speech processor programs for children using Med-El Maestro software. The secondary goals were (1) to compare the eSR and eCAP thresholds recorded using charge units in experienced adults fitted with Med-El Pulsar CI100 cochlear implants with most comfortable loudness levels (MCLs) obtained for the apical, medial and basal electrodes, and (2) to compare eSR and eCAP thresholds for the apical, medial and basal electrodes between adults and children. Methods: Fourteen children and 16 adults participated in the study. eSR and eCAP thresholds were measured in both groups using the auditory nerve response telemetry algorithm, with MCL being behaviourally measured only in the adult group. Results: In the adult population, the correlation between eSR threshold and MCL was better for apical, medial and basal electrodes than that between eCAP threshold and MCL. There was no significant difference in the means obtained for eCAP and eSR thresholds in children and adults for any of the electrodes tested. This finding suggests that in children, the correlations between eCAP thresholds and MCL values, and those between eSR thresholds and MCL values are not lower than those generally found in adults. Conclusions: Although the eSR threshold is a better predictor of MCL values, both eSR and eCAP thresholds can be useful tools for assisting with map creation for children.

Summary The objective of the work was to assess occurrence of central auditory processing disorders in children with dyslalia. Material and method The material included 30 children at the age 7–9 years old being under long-term speech therapy care due to articulation disorders. All the children were subjected to the phoniatric and speech examination, including tonal and impedance audiometry, speech therapist's consultation and psychologist's consultation. Electrophysiological (N2, P2, N2, P2, P300 record) and following psychoacoustic test of central auditory functions were performed (Frequency Pattern Test). Results Analysis of the results revealed disorders in the process of sound analysis within frequency and P300 wave latency prolongation in children with dyslalia. Conclusions Auditory processing disorders may be significant in development of correct articulation in children, they also may explain unsatisfactory results of long-term speech therapy.

This investigation was undertaken for perceptual and acoustic analysis of voice in patients with Reinke's oedemas treated with laser microsurgery. Material of the study included 45 patients in the age of 23 to 65 presenting to Foniatric Clinic with dysphonia in Reinke's oedemas. Patients were divided into 3 groups according to Yonakawa's classification of Reinke's oedemas. All patients were treated with CO2 laser microsurgery. Voice assessment was made subiectively with GRBAS scale and objectively using multidimensional voice parameters analysis (MDVP). The examination was undertaken preoperatively and 4 weeks after operation. The results of our study show relationship between quality of voice after surgery and the stage of evolution of Reinke's oedemas according to the applied classification.

This study shows that by using the round window approach and deep insertion, it is possible to reduce electrode insertion trauma (EIT), as indicated by the results of the hearing preservation marker.In this prospective study EIT was evaluated in 42 subjects with low frequency hearing before surgery with 28 mm round window deep insertion.The degree of hearing preservation was a marker of EIT. Pure tone audiometry, monosyllable testing was conducted preoperatively and then at 3, 6, and 13 months after surgery.Immediate hearing preservation (3 months postoperatively) was 92.9% (39/42). The surgery-related hearing preservation 13 months after surgery varied from 85% (34/40) to 90% (36/40). The ipsilateral implanted ear showed significant differences between preoperative and postoperative hearing thresholds (p0.005). Comparisons of thresholds for the control ear showed a significant difference between preoperative and postoperative thresholds tested 13 months after surgery (p0.05). When the subtraction factor of the mean contralateral hearing loss for each tested frequency for the same time interval was applied to the implanted ear, no significant hearing loss was found, showing that postoperative ipsilateral progressive hearing loss was caused by etiology rather than surgery.
