ABSTRACT Introduction Voice overuse may result in roughness, fatigue and pain while speaking. Vocal loading tasks have been used to assess changes in voice quality under different controlled settings. This study was done to document changes in voice characteristics before, immediately and 24 hours post-vocal loading task (VLT) using stroboscopic and acoustic analysis. Materials and methods Ten healthy adult males (age range: 20 to 40 years) with no apparent comorbid illness participated in the study. They were instructed to read the standard Rainbow passage at intensity above 75 dB SPL until they perceived any symptoms of fatigue/ strain. Stroboscopy and comprehensive voice assessment were done on all subjects before, immediate post VLT and 24 hours post VLT. Results Symptoms of vocal fatigue were noted on an average of 45 minutes of loud reading. Vocal fold edema, ventricular band hyperadduction and arytenoid congestion were noticed in immediate post task. The vocal fold movements were asymmetric and aperiodic with reduced mucosal wave and amplitude. Maximum phonation time (MPT) revealed statistically significant decrease (approximately 7 sec). Multiparametric acoustic analysis revealed a statistically significant increase in fundamental frequency, perturbation measures and lowest intensity with significant decrease in dysphonia severity index (DSI). All parameters (stroboscopic findings, perceptual, aerodynamic and acoustic analysis) showed values within normal limits after 24 hours post-task indicating recovery at 24 hours after vocal loading. Stroboscopy served as an evidence for structural and functional changes in the vocal fold. Changes in voice characteristics and recovery following vocal loading task can be documented using comprehensive voice assessment.

Abstract Purpose Endoscopic arytenoid abduction lateropexy (EAAL) is a reliable surgical solution for the minimally invasive treatment of bilateral vocal fold palsy (BVFP), providing a stable airway by the lateralization of the arytenoid cartilages with a simple suture. The nondestructive manner of the intervention theoretically leads to higher regeneration potential, thus better voice quality. The study aimed to investigate the respiratory and phonatory outcomes of this treatment concept. Methods 61 BVFP patients with significant dyspnea associated with thyroid/parathyroid surgery were treated by unilateral EAAL. Jitter, Shimmer, Harmonics to Noise Ratio, Maximum Phonation Time, Fundamental frequency, Voice Handicap Index, Dysphonia Severity Index, Friedrich’s Dysphonia Index, Global-Roughness-Breathiness scale, Quality of Life, and Peak Inspiratory Flow were evaluated 18 months after EAAL. Results All patients had a stable and adequate airway during the follow-up. Ten patients (16.4%) experienced complete bilateral motion recovery with objective acoustic parameters in the physiological ranges. Most functional results of the 13 patients (21.3%) with unilateral recovery also reached the normal values. Fifteen patients (24.6%) had unilateral adduction recovery only, with slightly impaired voice quality. Eleven patients (18.0%) had false vocal fold phonation with socially acceptable voice. In 12 patients (19.7%) no significant motion recovery was detected on the glottic level. Conclusion EAAL does not interfere with the potential regeneration process and meets the most important phoniatric requirements while guaranteeing the reversibility of the procedure—therefore serving patients with transient palsy. Further, a socially acceptable voice quality and an adequate airway are ensured even in cases of permanent bilateral vocal fold paralysis.

The Voice

Aim of study: Evaluation of the speech therapy on voice quality in patients with unilateral vocal fold palsy. Material and methods: The study group included 11 patients, 8 women and 3 men, in age between 16 to 72 years, with unilateral vocal fold palsy, diagnosed in ENT Department of Warsaw Medical University between 2017-2018. Each person completed questionnaires: the voice disability self-assessment scale (VHI), the voice-based quality of life (VRQoL) scale, the vocal tract discomfort scale (VTD). All questionnaires were completed twice, before and after the voice therapy. In addition, the acoustic analysis of the voice, the assessment of the maximum phonation time and the breathing tract were performed twice in each patient. Each of the patients had a voice rehabilitation consisting of a series of 10 meetings. Results: Statistical analysis of the results of maximum phonation time, the self-assessment of voice disability, the quality of life depending on the voice, discomfort of the vocal tract voice acoustic analysis showed statistically significant differences in the results before and after rehabilitation (p <0.005). In addition, the improvement of the respiratory tract was observed in the majority of patients. Conclusions: Speech therapy significantly affects the voice quality of patients with unilateral laryngeal nerve palsy.

Perceptual Evaluation

The objective of this study was to evaluate the effects on voice quality of augmentation by injection of minced fascia in patients with unilateral vocal fold paralysis. Preoperative and postoperative voice samples from 14 patients (6 men and 8 women; mean age, 59 years) were analyzed by computerized acoustic analysis and blinded perceptual evaluation. Statistically significant improvements were seen in perturbation measurements (jitter and shimmer), noise-to-harmonics ratio, and maximum phonation time. A panel of evaluators rated 10 of the 14 postoperative voices as normal or near-normal. Injection laryngoplasty with minced fascia offers a new, effective, well-tolerated, and inexpensive method to medialize a paralyzed vocal fold. The graft seems to survive well, as indicated by good vocal results with a follow-up ranging from 5 to 32 months.

Medialization Thyroplasty

Medialization thyroplasty (type I) is surgical procedure performed on the thyroid cartilage. The major indication for this surgery is significant glottis insufficiency due to unilateral vocal fold paresis. However the proce¬dure is also performed after vocal fold resections during cordectomy. The aim: The evaluation of voice results in patients after medialisation throplasty. Material and methods: In Otolaryngology Department of Medical University of Warsaw there were performed so far 8 thyroplasty procedures under local anaesthesia with implantation of medical silicon protesis. 6 patients had unilat¬eral vocal fold paresis and the rest two underwent in the past laser cordectomy due to T1a vocal carcinoma. Results: There were no complications during and post the surgery. The follow up examination in 1st , 3rd, 6th i 12th months postoperatively revealed for all patients significant improvement of glottal closure in laryngeal videostrobos¬copy. The voice quality improved both in perceptual evaluation (GRBAS scale) and acoustic analysis (F0, jitter, shim¬mer, NHR) in both patients groups. However the rate of improvement was much more significant in group with uni¬lateral vocal fold paresis. In all patients the maximum phonation time (MPT) increased. The self-evaluation of voice quality with Voice Handicap Index questionnaire confirmed also individual improvement. Conclusions: The speech rehabilitations is not successful in each patient with glottis insufficiency. The medialisation thyroplasty remains the standard procedure for permanent improvement of voice quality in those cases.

Laryngeal Framework Surgery

Objective.Autologous fat injection laryngoplasty is ineffective for some patients with iatrogenic vocal fold paralysis, and additional laryngeal framework surgery is often required. An acoustically measurable outcome predictor for lipoinjection laryngoplasty would assist phonosurgeons in formulating treatment strategies.Methods.Seventeen thyroid surgery patients with unilateral vocal fold paralysis participated in this study. All subjects underwent lipoinjection laryngoplasty to treat postsurgery vocal hoarseness. After treatment, patients were assigned to success and failure groups on the basis of voice improvement. Linear prediction analysis was used to construct a new voice quality indicator, the number of irregular peaks (NIrrP). It compared with the measures used in the Multi-Dimensional Voice Program (MDVP), such as jitter (frequency perturbation) and shimmer (perturbation of amplitude).Results.By comparing the [i] vowel produced by patients before the lipoinjection laryngoplasty (AUC = 0.98, 95% CI = 0.78–0.99), NIrrP was shown to be a more accurate predictor of long-term surgical outcomes than jitter (AUC = 0.73, 95% CI = 0.47–0.91) and shimmer (AUC = 0.63, 95% CI = 0.37–0.85), as identified by the receiver operating characteristic curve.Conclusions.NIrrP measured using the LP model could be a more accurate outcome predictor than the parameters used in the MDVP.

Weighted Combination

The vocal quality of a patient is modeled by means of a Dysphonia Severity Index (DSI), which is designed to establish an objective and quantitative correlate of the perceived vocal quality. The DSI is based on the weighted combination of the following selected set of voice measurements: highest frequency (F 0 -High in Hz), lowest intensity (I-Low in dB), maximum phonation time (MPT in s), and jitter (%). The DSI is derived from a multivariate analysis of 387 subjects with the goal of describing, purely based on objective measures, the perceived voice quality. It is constructed as DSI=0.13 x MPT + 0.0053 x F 0 -High – 0.26 x I-Low – 1.18 x Jitter (%) + 12.4. The DSI for perceptually normal voices equals +5 and for severely dysphonic voices –5. The more negative the patient's index, the worse is his or her vocal quality. As such, the DSI is especially useful to evaluate therapeutic evolution of dysphonic patients. Additionally, there is a high correlation between the DSI and the Voice Handicap Index score.

AbstractObjective:To investigate perceptual, acoustic and aerodynamic voice parameters in obese individuals.Methods:Twenty obese and 20 normal-weight volunteers underwent voice evaluation by laryngoscopy, acoustic analysis, aerodynamic measurement and perceptual analysis (using the grade-roughness-breathiness-asthenia-strain (‘GRBAS') scale and the Voice Handicap Index 10 scale). Data from both subject groups were compared.Results:No difference was found in acoustic analysis parameters between the two groups (p > 0.05). Maximum phonation time in the obese group (mean ± standard deviation, 19.6 ± 4.9 seconds) was significantly shorter than in controls (26.4 ± 4.1 seconds) (p < 0.001), although the s/z ratio was very similar between the two groups. In the obese and control groups, the mean ± standard deviation grade-roughness-breathiness-asthenia-strain scores were 1 ± 1.3 and 0.2 ± 0.6 (p = 0.002) and the mean ± standard deviation Voice Handicap Index 10 scores were 0.5 ± 1.2 and 1.2 ± 1.7 (p = 0.27), respectively.Conclusion:Obese individuals had poorer vocal quality as judged by the grade-roughness-breathiness-asthenia-strain scale, and reduced maximum phonation time. However, there was no change in voice quality as assessed by acoustic analysis and Vocal Handicap Index 10 score, compared with controls.

Introduction. Voice express the psyche and personality of a person. Psychogenic dysphonia is called Phononeurosis. Neurosis, depression or family, occupational and social conflicts are the cause of voice disturbances. The most frequent type of dysphonia is hyperfunctional dysphonia, rarer – hypofunctional type. Aim. The aim of this study is an analysis of voice quality and diagnosis of clinical type of psychogenic dysphonia. Material and methods. The analyzed group consisted of 50 patients with voice disorders treated in 2017 and the control group – 30 people with physiological voice. In the diagnosed group 60% of patients were treated for neurosis, 12% due to depression, the others reported conflict situations. In the diagnosis of clinical type of psychogenic dysphonia GRBAS scale was used, maximum phonation time (MPT) and type of breathing were assessed. The visualisation of the larynx was performed using High Speed Digital Imaging (HSDI) technique. The parametric acoustic evaluation of voice was conducted. Results. The most often clinical type of psychogenic dysphonia was hyperfunctional dysphonia, rarer hypofunctional type and vestibular voice. Dysphonia occurred the most often in women during the highest professional activity period. In the diagnosis of clinical type HSDI technique was especially useful allowing to visualization of the real vocal fold vibration and objective differentiation of hyper- and hypofunctional dysphonia. The acoustic analysis of the voice objectively confirmed the presence non-harmonic components – noise generated in the glottis in hypofunctional dysphonia. Disturbances in the way and breathing type caused irregularities in respiratory-phonic and articulation coordination.

Introduction: The term ‘voice' is the acoustic energy generated from the vocal tract that are characterized by their dependence on vocal fold vibratory pattern. Teachers as professional voice users are afflicted with dysphonia and are discouraged with their jobs and seek alternative employment. Loud speaking and voice straining may lead to vocal fatigue and vocal fold tissue damage.  Methods: Sixty teachers from various schools, volunteered to participate in this study. Acoustic analysis Doctor Speech Tiger Electronics, USA was used to assess the voice quality of the school teachers before and after teaching practice. The data were collected and analyzed using Doctor Speech Tiger Electronics, USA. Analysis was performed in terms of perturbation (jitter and shimmer), fundamental frequency, harmonic to noise ratio and maximum phonation time. Results: We found statistically significant difference in all the four parameters except the Jitter value. The fundamental frequency and shimmer value has significantly increased (P<0.001) and (P=0.002) respectively after teaching practice. Unlikely, there was significant decrease in harmonic to noise ratio value (P<0.001) and maximum phonation time value (P<0.01) after teaching practice. Conclusions: Vocal abuse, overuse, or misuse in teaching practice over a long period of time can result in inadequate phonatory pattern due to vocal fold tissue damage, which ultimately results in vocal nodules or polyps. So voice evaluation is particularly important for professional voice users and for the people who are concerned about their quality of voice.
