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.

Introduction. Laryngeal pathology occupies a leading place in the general structure of diseases of the upper respiratory tract, chronic edematous-polypous laryngitis, Reinke-Gayek edema accounts for 5.5% of all benign diseases of the vocal folds. The main method of treating Reinke-Gayek's disease is surgical treatment, which consists in removing excess mucosa, or “stripping” - tearing a strip of mucosa with forceps from the vocal fold. One of the main principles of laryngeal surgery is the maximum preservation of the structures of the vocal fold, obtaining a flexible vibration of the muscular-membranous part and the mucous membrane of the vocal fold.Purpose. The purpose of our work is to improve the effectiveness of treatment of chronic edematous-polypous laryngitis using a CO2 laser.Tasks. To develop a differentiated approach to the surgical treatment of chronic edematous-polypous laryngitis using a carbon dioxide laser.Materials and Methods. We treated 46 patients with Reinke-Gayek disease, including 35 women and 11 men. The age of the patients ranged from 40 to 67 years. Preoperative examination included endoscopic examination, laryngostroboscopy. The type was determined according to the classification of H. Yonekawa, for the choice of further surgical tactics. In type II, an incision of the mucosa, aspiration of gelatinous matter from the Reinke space, and laying of the mucosa were performed. With type III, it is made by forming M-shaped flap to close the defect.Results. All patients in the preoperative period were surveyed with the VOICE HANDICAP INDEX(VHI-30) questionnaire, laryn-gostroboscopy, and maximum phonation time. In the postoperative period, the examination was performed twice, 1 month after the operation and 3 months after the operation. There is a significant increase in indicators, an increase in the maximum phonation time, a decrease in VHI-30 points.Conclusion. The use of this technique allowed to significantly accelerate the recovery of the voice, reduce the time spent in the hospital, minimally damaging the structure of the mucous membrane of the vocal folds.

Purpose: This study aimed to analyze the immediate effect on a singer's voice of a flexible silicone tube immersed in water combined with ascending and descending vocalise scales compared with ascending and descending vocalise scales alone. Method: A pre- and post-intervention quasi-experimental study was conducted. Thirty adult singers between 18 and 45 years old with no laryngeal disorders performed the two techniques for 3 min each on different days. Acoustic measurements of frequency, jitter, shimmer, glottal-to-noise excitation ratio, noise, smoothed cepstral peak prominence (CPPS), maximum phonation time (MPT), voice range profile, and self-perceived vocal effort (Borg Category Ratio 10-BR Scale adapted for vocal effort) were assessed before and after performing the techniques. Results: The results indicated an increase in singers' CPPS and MPT values and a decrease in shimmer and noise when performing with a flexible silicone tube immersed in water combined with vocalise. The singers reported a perception of decreased vocal effort after both methods. However, the diminished perceived vocal effort became more pronounced with the tube phonation technique combined with vocalise. Conclusions: Phonation in tubes combined with vocalise improved the vocal acoustic parameters (including cepstral measurements), increased MPT, and diminished perceived vocal effort. Although using vocalise alone diminished perceived vocal effort, this decrease was more pronounced in the tube phonation technique combined with vocalise.

Objective: The purpose of this study was to investigate the gender and age effect on lung function measures and maximum phonation time in the age range of 20-60 years. The present study also aimed to evaluate correlation between FEV1 and maximum phonation time. Study Design: Cross- sectional study, Convenience sampling method Method: The lung function measures (FVC, FEV1, & FEV1/FVC) and maximum phonation time were obtained from 200 healthy participants in the age range of 20-60 years. These participants were divided into two groups (Group I - 20- 40 years & Group II - 41- 60 years) with equal number of males and females in each group. The lung function measures were obtained using Easy on PC spirometer. Three consecutive trials were collected for MPT using stopwatch. Mann- Whitney U test was used to determine effect of age and gender on lung function measures and MPD. Spearman's Rank Correlations were performed to identify is there any significant relationships between the FEV1 and MPT of /a/, /i/, /u/, /s/, and /z/. Results: There were significant effect of gender on FVC, FEV1, & MPT except on FEV1/FVC. There was significant effect of age in both genders on FVC, FEV1, & FEV1/FVC. There was no significant effect of age in both genders on MPT /i/, /u/, /s/, and /z/ except MPT /a/ for males. FEV1 showed significant positive correlation with MPD (/a/, /i/, /u/, /s/, and /z/). Conclusions: The mean FVC and FEV1 were lower in females and higher in males in both the age groups. Maximum phonation time of /a/, /i/, /u/, /s/, and /z/ was longer in males as compared to female. Age has inverse effect on lung function measure and MPT. FEV1 showed positive correlation with MPT, which indicates that FEV1 increases with increase in MPT. Key words: Maximum Phonation Time, Lung Function Measures.

Introduction: Acoustic analysis of voice is a method for assessing its quality, which has a relatively low cost. It quite simple to use, and is non-invasive. One of the programs of spectral analysis of voice is the program Praat, which allows to explore its acoustic characteristics and analyze the forms, also its allows to edit sound segments and print the spectrogram. The purpose: Investigate the acoustic parameters of the voice Ukrainians of different ages and genders and perform the calculation of reference intervals (RI) for these indicators. Material and methods: We had examined150 healthy Ukrainians aged 18 to 70. The study was performed using a Behringer C1U condenser microphone and Praat software (version 5.1.12.). The following acoustic characteristics of the voice were studied: the fundamental frequency of voice (F0) in Hz, the maximum phonation time (MPT) in seconds, the Harmonic to Noise Ratio (HNR) in dB, Jitter in%, Shimmer in%. Four groups were formed for the study: 1a – young women (18-44 years); 2a – young men (18-44 years); 1b – middle-aged women (45-59 years); 2b – middle-aged men (45-59 years). Results: Young and middle-aged men showed significantly higher MPT than women of relevant age. The value of MPT in women with age increased slightly, in men decreased slightly. RI for the indicator of MPT, in 1a group is 11,35-31,28 s, in 2a group – 15,55-39,53 s, in 1b group -14,30-33,01 s, and in 2b group –12,59-31,90 s. The value of F0 in young and middle-aged women is statistically higher than in men of the same age group (p <0.001). With age, this figure decreases slightly in women and men. RI for the indicator F0, in 1a group is 107,0-316,5 Hz, in 2a group – 94,1-139,3 Hz, in 1b group – 94,3-339,1 Hz, and in 2b group – 80,3 -174,3Hz.A comparative analysis of the HNR in young and middle-aged men didn’t show significant differences. In middle-aged women this value is significantly higher than in young women. RI for the HNR in group 1a is 14,194-26,946 dB; in group 2a – 17,328-28,675 dB; in group 1b -15,254-26,536 dB, and in group 2b – 13,545-30,368 dB. The Jitter index in men and young women does not differ statistically. This figure increases statistically in men with age, in women this rate the same level. RI for the Jitter in 1a group – 0,110-0,436%; in 2a group – 0,101-0,472%; in 1b group – 0,094-0,520% and in 2b group – 0,117-0,460%. A comparative analysis of Shimmer in men and young women didn't show significant differences, but in middle-aged women this figure decreased statistically compared to young women. In men, this figure has not changed with age. The RI for the Shimmer index is 1,974-14,128% in group 1a; 2,592-12,378% in group 2a; 2,008-6,788% in group 1b; 2,016-12,260% – In group 2b. Conclusions: Indicators of spectral analysis of voice in young and middle-aged women and men are relatively stable and do not change significantly in this time period.

Objectives: We aim to analyze long-term voice outcomes and Quality of Life (QoL) in patients undergoing Open Partial Horizontal Laryngectomy Type II (OPHL Type II) and to compare them to those obtained by patients undergoing Total Laryngectomy (TL) with voice prosthesis (VP). Design: Cross-sectional cohort study Setting: patients undergoing surgery for advanced laryngeal cancer, assessed during the usual follow-up consultations at the Phoniatric Unit (February 2020-December 2020). Participants: Forty-five patients were enrolled and divided into two groups: OPHL Group and TL Group. Main outcomes measures: Maximum phonation time, INFV0 scale, I-SECEL, UWQoL-V4 and MDADI questionnaires were used to assess the long-term outcomes. Results: Voices of patients undergoing OPHL Type II were worse than those of laryngectomized patients with VP. Nevertheless, scores in voice and dysphagia-related QoL were comparable and scores in the Social domain of QoL were better in OPHL group. Conclusions. OPHL Type II allows an acceptable voice recovery and a satisfactory QoL.

Introduction Laryngopharyngeal reflux disease can alter the structural and functional integrity of the vocal fold. Objectives of the study was to determine the effect of Laryngopharyngeal Reflux Disease (LPRD) on selected Acoustic, Aerodynamic and perceptual parameters of voice and to establish its effectiveness in therapeutic outcome. Materials and Methods The number of patients enrolled for this prospective observational study was 65, all with Reflux symptom index (RSI) more than 13. Quality of life was evaluated using voice handicap index (VHI). Perceptual evaluation of voice done by Grade Roughness Breathiness Asthenia Strain score (GRBAS) followed by acoustic and aerodynamic analysis. Patients were started on a once daily proton pump inhibitor therapy for 3 months along with vocal hygiene measures and RSI, VHI and voice analysis repeated after the treatment. Results There was significant improvement in the RSI score after treatment. Percent jitter and shimmer showed significant improvement in males post treatment (p value:<0.05). Harmonic to noise ratio improved 3 months post treatment in both sexes. Improvement noted in Maximum phonation time and GRBAS score except asthenia and strain post treatment. Conclusion Measurement of voice quality can be used as an effective tool to monitor the efficiency of treatment of LPRD.

Objective This series evaluates the long-term results of autologous adipose injection (AAI) in patients older than 65 years with presbyphonia. Study Design Retrospective cohort study. Setting Academic secondary medical center. Methods This was a retrospective study with a minimum follow-up of 12 months. All patients underwent AAI for atrophy of both vocal folds due to presbyphonia. We measured subjective parameters as Voice Handicap Index–10 (VHI-10) or GRBAS scale (grade, roughness, breathiness, asthenia, strain) and objective measures such as maximum phonation time (MPT) or square pixel closure defect. We reviewed the medical records of patients undergoing AAI during the 2011-2018 period. An analysis of the demographic variables of the group was performed, as well as the values of VHI-10, GRBAS, and MPT, and the minimum closure defect measured in square pixels and the number of closed frames in the glottal cycle before and after the intervention. Results At 12 months, 17 of 18 patients reported subjective and VHI-10 improvement. The mean preoperative VHI-10 (26.7) was significantly higher than the postoperative value (14.4), and the GRBAS scale had a preoperative mean of 8.7 and a postoperative mean of 4.3, both with statistical significance. MPT increased from 7.7 to 12.4 seconds ( P < .0001). The minimum closure defect measurements obtained in square pixels changed from 305 to 124, achieving complete closure in 3 patients. The closed phase of the glottal cycle change from 14.3% to 38.2% after the AAI. Conclusions AAI improves long-term vocal fold closure, demonstrating utility in patients with presbyphonia.
