Validity, reliability and reproducibility of the VLS parameters form for the collection of videolaryngostroboscopic basic findings.

OBJECTIVE: The videolaryngostroboscopy parameters form (VLSP form) is a diagnostic tool for the collection of videolaryngostroboscopic basic findings through the evaluation of 12 parameters. The aim of the present study is to preliminarily investigate intra- and inter-rater reliability, validity and responsiveness of the VLSP form. METHODS: A study on a total amount of 160 forms for the evaluation of VLS basic findings was carried out. 80 forms were scored through the VLSP form and 80 with the Voice Vibratory Assessment with Laryngeal Imaging (VALI) form Stroboscopy (S) by four expert phoniatricians, that blindly scored the VLS recordings of 5 subjects without voice disorders and 5 patients with organic voice disorder before and after successful phonosurgery. Intra-rater and inter-rater analysis have been performed for both forms. The scores obtained through VLSP form and VALI form S have been compared to analyse concurrent validity, while VLSP scores before and after phonosurgery have been compared to analyse responsiveness. Finally, each rater annotated the "difficulty" in rating every parameter and its "importance" for the diagnosis. RESULTS: The VLSP form showed good inter- and intra-rater reliability. It showed a good accuracy for the documentation of changes of laryngeal anatomy and function after phonosurgery, similarly to the VALI form S. The 12 parameters of the VLSP form were judged "Slightly Important" in 28.3% of the samples, "Very Important" in 64.8% of the samples, "Not Difficult" in 73.1% of the samples. CONCLUSIONS: The results of the present study suggest that the VLSP form is comparable to the VALI form S for the evaluation of videolaryngostroboscopic parameters and is a valid, reliable and reproducible diagnostic tool. It can help voice clinicians in the evaluation of VLS examinations and it allows for a punctual assessment of modifications in laryngeal anatomy and function in pathological conditions and after phonosurgery.

Effects of intracordal trafermin injection on mutational voice disorder.

INTRODUCTION: Mutational voice disorder is the inability of the voice to adjust to the changes in the larynx during puberty, resulting in the speaking fundamental frequency failing to decrease. Standard treatments for mutational voice disorder are voice therapy and thyroplasty. However, voice therapy takes time to show its effects, and thyroplasty is highly invasive. Herein, we present a case of mutational voice disorder successfully treated with intracordal trafermin injection. CASE SUMMARY: A 31-year-old male patient was diagnosed with mutational voice disorder and offered standard treatment, but he requested a less invasive treatment with early effects. We performed intracordal trafermin injection with his consent. Two months after the procedure, the speaking fundamental frequency decreased from 155.5 Hz to 93.0 Hz, and the voice handicap index decreased from 14 to 2. DISCUSSION: This case suggests that intracordal trafermin injection is an effective treatment option for mutational voice disorder. Furthermore, compared with the standard treatment methods, it is less invasive and provides effects shortly with only one injection.

Effect of adenoid size on the post-adenoidectomy hypernasality in children with a normal palate.

PURPOSE: Adenoidectomy, either alone or with tonsillectomy, is a common surgical procedure in the field of pediatric otorhinolaryngology. Resonance function may be altered postoperatively in the form of hypernasality, which is usually transient. This study aimed to investigate the effect of adenoid size on post-adenoidectomy hypernasality in children with a normal palate. METHODS: Seventy-one children with different degrees of adenoid hypertrophy were included in this prospective observational study. Endoscopic assessment of the adenoid size and preoperative and postoperative evaluation of speech (at 1 and 3 months) with auditory perceptual assessment (APA) and nasometry were performed. RESULTS: APA showed preoperative hyponasality in 59.1% of children and was found to be significantly related to the adenoid size, with more hyponasality in grades 3 and 4. One month postoperatively, hypernasality was detected in 26.7% of patients and was found to be related to the preoperative adenoid size with higher hypernasality in grades 3 and 4. Three months postoperatively, all patients had gained normal nasality except one (1.4%) who was subjected to a longer follow-up period. Nasometric assessment showed significant differences at the three visits (pre, 1, and 3 months postoperatively), with a negative correlation between the grade of adenoid size and nasalance scores preoperatively and a significant positive correlation between them at 1 month postoperatively. However, no significant correlation was detected at 3 months postoperatively. CONCLUSION: Transient hypernasality may develop in some patients after adenoidectomy, especially in children with a larger preoperative adenoid size. However, transient hypernasality generally resolves spontaneously within 3 months.

Sphincter Pharyngoplasty for Velopharyngeal Dysfunction: Impact of 22q11.2 Deletion Syndrome.

OBJECTIVE: Patients with 22q11.2 deletion syndrome (22q11DelS) often present with velopharyngeal dysfunction (VPD). VPD in patients with 22q11DelS is multifactorial beyond velopharyngeal insufficiency (VPI) alone, and differences in surgical outcomes are poorly understood. Our objective was to determine whether patients with 22q11DelS have an increased risk for persistent VPI after sphincter pharyngoplasty compared to patients without 22q11DelS. METHODS: We completed a retrospective cohort study of patients with 22q11DelS undergoing sphincter pharyngoplasty between 1995 and 2019 using a VPD clinic database. Patients with 22q11DelS were compared to a cohort of 2:1 frequency-matched (age, degree of velopharyngeal closure) patients without 22q11DelS. Variables included patient characteristics, surgical history, perceptual speech evaluation, and degree of closure on nasopharyngoscopic evaluations. Primary outcomes included postoperative VPI severity and hypernasality. Speech and nasopharyngoscopic characteristics were compared using Fisher's exact test. Postoperative VPI severity and hypernasality were compared between groups via relative risks (RR) from mixed effects Poisson regression models, with random effects of age and velopharyngeal closure. RESULTS: 134 patients (51 22q11DelS, 83 matched) were included, with mean age of 7.3 years (standard deviation 3.0) and 50% male. Cohorts had similar preoperative speech characteristics and nasopharyngoscopic findings. Patients with 22q11DelS had similar postoperative VP function as patients without 22q11DelS (RR 0.85, CI 0.46-1.57 for VPI severity, RR 0.83, CI 0.45-1.53 for hypernasality). Even after adjusting by preoperative variables, no differences were seen between both groups. CONCLUSION: Matched for age and pre-operative velopharyngeal closure, patients with and without 22q11DelS and VPI had similar benefits after sphincter pharyngoplasty. LEVEL OF EVIDENCE: Non-randomized controlled cohort study, 3 Laryngoscope, 133:2813-2820, 2023.

Acoustic, Perceptual, and Laryngoscopic Changes Post Vocal Abuse at a College Fest.

INTRODUCTION: College students use their voices at excessively loud intensities and long durations during college fests. The accumulative effect of vocally abusive behaviors in the presence of high ambient noise, poor vocal hygiene, and other environmental factors contribute significantly towards reducing vocal effectiveness in college students. OBJECTIVE: The present study aimed to study the effect of a vocally demanding situation (college Fest) on perceptual and objective voice features of college students. METHODOLOGY: In this study, a total number of 27 undergraduate female students participated in the age range of 18-27 years. Pre-test-post-test research design was applied. Data analysis consisted of video stroboscopic examination, acoustic analysis using the Multi-dimensional voice program (MDVP), and perceptual evaluation with the GRBAS scale. The data obtained were processed using descriptive statistics and non-parametric tests to determine the difference in each measured parameter pre- and postfest. RESULTS AND DISCUSSION: Incomplete glottis closure, asymmetric vibration of vocal folds, and aperiodicity of vocal folds increased significantly postcollege Fest. GRBAS parameters also showed a change from pre Fest scores on grade (hoarseness) increased by 38%, breathiness in 34%, roughness in 26%, Asthenia in 15%, and strain increased in 38% participants. A P-value estimation revealed significantly higher scores in Jitter percent, Shimmer percent, and relative average perturbation than pre-fest scores. CONCLUSION: The results of the present study indicate a high risk of vocal disorders among college students post Fest. This study suggests a potential unmet need for college students to receive education before cultural events on optimal vocal usage, vocal hygiene, and an appropriate period of vocal rest.

OpenHSV: an open platform for laryngeal high-speed videoendoscopy.

High-speed videoendoscopy is an important tool to study laryngeal dynamics, to quantify vocal fold oscillations, to diagnose voice impairments at laryngeal level and to monitor treatment progress. However, there is a significant lack of an open source, expandable research tool that features latest hardware and data analysis. In this work, we propose an open research platform termed OpenHSV that is based on state-of-the-art, commercially available equipment and features a fully automatic data analysis pipeline. A publicly available, user-friendly graphical user interface implemented in Python is used to interface the hardware. Video and audio data are recorded in synchrony and are subsequently fully automatically analyzed. Video segmentation of the glottal area is performed using efficient deep neural networks to derive glottal area waveform and glottal midline. Established quantitative, clinically relevant video and audio parameters were implemented and computed. In a preliminary clinical study, we recorded video and audio data from 28 healthy subjects. Analyzing these data in terms of image quality and derived quantitative parameters, we show the applicability, performance and usefulness of OpenHSV. Therefore, OpenHSV provides a valid, standardized access to high-speed videoendoscopy data acquisition and analysis for voice scientists, highlighting its use as a valuable research tool in understanding voice physiology. We envision that OpenHSV serves as basis for the next generation of clinical HSV systems.

Voice After Rhinoplasty. An Important Question for the Opera Singers.

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

'Mini-Microsuture Technique' for Phonosurgery: A New Simplified Method.

INTRODUCTION: Phonomicrolaryngeal surgery involves the surgical treatment of benign disorders of the vocal folds. Postoperative scar tissue in vocal fold mucosa is undesired because mucosal hypodynamia may lead to prolonged impairment in voice quality. This study aims to present and share the outcomes of a new endolaryngeal suture technique. METHODS: This study consists of patients who underwent vocal fold surgery followed by endolaryngeal microscopic suturation with a technique that we call the "mini-microsuture technique" between January 2018-December 2019. Videolaryngoscopic images were examined to observe the tissue healing process (suture elimination time, mucosal scar status, and wave pattern) at the first and the fourth week postoperatively. RESULTS: A retrospective analysis was made in 144 (57 males (39.5%) and 87 females (60.5%)) patients who underwent phonomicrosurgery with "Mini-microsuture technique." Mean age was 40.61 ± 13.54 (10-78) years. There were multiple pathological lesions in 41.66% (n: 60) of our patients, and 58.33% (n: 84) of them had single-lesion. 63.88% (n: 92) of the patients had bilateral vocal fold lesions where 36.22% (n: 52) of the patients had pathology in one vocal fold. CONCLUSIONS: The "mini-microsuture technique" is an easy and functional procedure that can be performed by a single surgeon under microscopy, which minimizes tissue trauma, prevents mucosal hypodynamia, and provides a better anatomical structure postoperatively for a symmetrical vibration. The technique does not significantly prolong operation time when mastered and is a cost-effective method in which surgery which can be concluded using a single suture material.

Speech Performance after Anterolateral Thigh Phonatory Tube Reconstruction for Total Laryngectomy.

OBJECTIVE: Traditionally, after total laryngopharyngectomy (TLP), patients cannot speak without a prosthesis or an artificial larynx. In Taiwan, most patients use a commercialized pneumatic laryngeal device (PLD). Phonatory tube reconstruction with the anterolateral thigh (ALT) flap is a novel, modified version of synchronous digestive and phonatory reconstruction involving a free muscular cutaneous flap. This study reviewed and compared speech performance between patients who underwent novel flap reconstruction and conventional PLD users. METHOD: We retrospectively reviewed patients with laryngeal or hypopharyngeal cancer who underwent TLP from August 2017 to September 2019. The voice handicap index (VHI), speech intelligibility, acoustic and aerodynamic analysis results, and speech range profile (SRP) were compared between patients who underwent ALT phonatory tube reconstruction (ALT group) and those using PLDs (PLD group). RESULTS: Twenty patients were included; 13 patients were included in the ALT group, and 7 patients were included in the PLD group. Compared to the PLD group, the ALT group had a better fundamental frequency range (P < .001) and semitone range (P < .001) during speech but showed worse jitter, shimmer, and harmonic-to-noise ratios. The two groups showed comparable VHI and speech intelligibility performance. CONCLUSIONS: The ALT phonatory tube, a novel flap for reconstruction, can restore digestive and voice functions simultaneously. Compared with PLD use, ALT phonatory tube reconstruction yields an improved speech range and comparable levels of voice handicap and speech intelligibility, suggesting that the technique is a good alternative for patients after TLP.

Union of the European Phoniatricians' position statement on the exit strategy of phoniatric and laryngological services: staying safe and getting back to normal after the peak of coronavirus disease 2019 (issued on 25th May 2020).

BACKGROUND: The following position statement from the Union of the European Phoniatricians, updated on 25th May 2020 (superseding the previous statement issued on 21st April 2020), contains a series of recommendations for phoniatricians and ENT surgeons who provide and/or run voice, swallowing, speech and language, or paediatric audiology services. OBJECTIVES: This material specifically aims to inform clinical practices in countries where clinics and operating theatres are reopening for elective work. It endeavours to present a current European view in relation to common procedures, many of which fall under the aegis of aerosol generating procedures. CONCLUSION: As evidence continues to build, some of the recommended practices will undoubtedly evolve, but it is hoped that the updated position statement will offer clinicians precepts on safe clinical practice.

Management of presbyphonia: A systematic review of the efficacy of surgical intervention.

OBJECTIVE: The aging larynx undergoes structural changes that have functional consequences for voice production known as presbyphonia. Treatment of presbyphonia includes voice therapy and surgery. This review seeks to examine voice outcomes after surgery for presbyphonia. DATA SOURCES: Three electronic databases (PreMed, ScienceDirect, Embase) were reviewed for articles published between 1 January 1900 and 1 June 2019. REVIEW METHODS: Original English-language studies examining surgical treatment of presbyphonia in elderly patients (≥65 years) were included according to PRISMA. Two researchers independently analyzed articles. Outcome measures were extracted from and qualitatively compared across studies. RESULTS: Of the 118 articles identified, five satisfied eligibility criteria. In all studies, diagnosis of presbyphonia was based on videostroboscopy. 85 patients (61M, 21F) were evaluated. 37.6% underwent implantation thyroplasty (IT), 48.2% underwent injection augmentation (IA), 7.1% underwent both, and 7.1% underwent basic-fibroblastic growth factor (b-FGF) injection. Average patient age was 71.3 years. Average follow-up time was 5.4 months. Three months post-intervention, IT patients self-reported greater improvement in quality of life (QoL) metrics compared to IA patients. Aerodynamic measures, like mean phonation time, were significantly improved in IT and IA, but not b-FGF-injected patients. All patients experienced improvements in the auditory perception of voice three months post-intervention. CONCLUSION: Surgical modalities currently utilized for presbyphonia include IT and IA, with bFGF-injection being trialed abroad. IT patients reported enhanced QoL relative to IA and bFGF-injected patients. Overall there is a paucity of high-power, prospective studies that explore the efficacy of these modalities. Moreover, wide variability exists in reported outcomes among published studies.

From Voice Clinic to Operating Room: Are We Out of Tune?

INTRODUCTION: To determine the consistency and accuracy of preoperative diagnosis in the voice clinic with intraoperative diagnosis and to suggest a standardized laryngeal examination protocol in the UK that is supported by evidence-based findings. METHOD: From January 2011-September 2014, 164 patients were referred to the Multidisciplinary Team voice clinic and diagnosed with laryngeal pathology that required phonosurgery. The visualization (videostrobolaryngoscopy) in clinic was performed using either rigid laryngoscope or a video-naso-laryngoscope. Intraoperatively, laryngeal visualization and surgical procedure was conducted using Storz Aida HD system, 10-mm rigid laryngoscope 0° or 5-mm rigid laryngoscope 0°/30° and a Zeiss S7 microscope. RESULTS: Of the 164 patients seen in the multidisciplinary voice clinic, 86 clinic diagnoses were confirmed intraoperatively (52.4%), 15 patients had the diagnosis confirmed intraoperatively with additional lesion found (9.1%). The clinic diagnosis changed intraoperatively in 63 cases (38.4%). 61 (37.2%) patients seen in the voice clinic were diagnosed with cyst, in 39.3% the diagnosis was confirmed intraoperatively with 5 cases (8.2%) having an additional diagnosis. Twenty (12.2%) patients were diagnosed with polyps, with 80% confirmation intraoperatively; 3 patients (10%) had an additional diagnosis. CONCLUSION: Videolaryngostroboscopy imaging of the larynx provides an outpatient tool for accurately diagnosing more than 50% of laryngeal pathologies when interpreted by multidisciplinary voice clinicians. However direct laryngeal examination under general anesthesia remains the gold standard when obtaining accurate diagnoses of laryngeal pathology. Patients diagnosed with nonorganic voice disorders should be considered for direct laryngoscopy under general anesthetic should they fail to respond to conservative management.

Application of Thulium Laser as Office-based Procedure in Patients With Vocal Fold Polyps.

PURPOSE: To report the voice outcome measures of thulium laser therapy as an office procedure in patients with vocal fold polyps. METHOD: This is a retrospective chart review of all patients with vocal fold polyps who underwent office-based thulium laser treatment between November 2016 and December 2017. Demographic data were collected. Objective voice outcome measures included extent of resolution, type of closure, and mucosal wave characteristics. Also, subjective outcome measures were reported, namely, Voice Handicap Index-10. RESULTS: A total of 20 patients were enrolled with a mean age of 50.95 ± 14.70 years. All patients had unilateral vocal fold polyps except for one who had bilateral polyps. Out of the 20 patients, 16 had complete regression of disease and 4 had partial regression. The number of patients with incomplete glottal closure decreased from 12 pretreatment to only 1 patient posttreatment, and the number of patients with impaired mucosal waves decreased from 13 to 5. There was also a significant decrease in the mean VHI-10 score before and after treatment (15.61 vs. 4.61 P value < 0.001). CONCLUSION: Thulium laser can be used as an office procedure for the treatment of vocal fold polyps.

Early Injection Laryngoplasty After Surgery: 30 Cases and Proposed Aspiration Assessment Protocol.

Vocal fold movement impairment may significantly compromise postoperative recovery and quality of life of patients following thoracic or cardiothoracic surgery or prolonged intubation. The literature is limited and there is no standard screening protocol for the optimal postoperative swallowing and aspiration evaluations. We performed retrospective review of adult patients undergoing early vocal fold (VF) injection laryngoplasty for acute postoperative Vocal fold movement impairment (<30 days) that had both pre- and postinjection speech language pathologist (SLP) performed swallowing/aspiration evaluations. Records were reviewed for demographics, clinical characteristics, procedural details, and short-term outcome measures of oral intake. In total, 30 patients were included, and had data on swallowing/aspiration studies before and after the VF injection laryngoplasty. Most of the patients were injected within 5 days following the laryngologist evaluation and within 14 days following the iatrogenic recurrent laryngeal nerve injury (23/30, 76.7%). The majority of patients were injected at the bedside by awake transcutaneous injection (22/30, 73.3%), six patients were injected in the operating room under general anesthesia, and two at the outpatient clinic. Pre- and postinjection SLP evaluations included clinical bedside assessment or instrumental evaluation. Following VF injection laryngoplasty, oral diet advancement was noted in 81.8% of the patients that were nil per os before the injection (18/22). No complications were noted. In conclusions, acute VFMI following surgery requires immediate diagnosis and therapeutic strategy to minimize postoperative complications and to overcome impairments in the voice, swallow, and cough. Otolaryngology-SLP interdisciplinary aspiration and swallowing assessment protocol is proposed based on our experience and an extensive literature review.

Anesthetic Management for Medialization Laryngoplasty Performed Under Concurrent Dexmedetomidine, Remifentanil, and Propofol Infusions.

INTRODUCTION: Type I thyroplasty, or medialization larygoplasty (ML), is a procedure which improves the voice by medializing a vocal fold with a permanent implant. Anesthetic management of these cases is challenging because patients can require periods of deep sedation followed by fully awake moments for phonation to assess the implant size. We present our experience of ML with or without arytenoid adduction (AA) using a multimodal anesthetic regimen consisting of concurrent infusions of dexmedetomidine, remifentanil, and propofol. METHODS: This is a retrospective case series of patients anesthetized using this protocol from June 1, 2015 through June 30, 2017. RESULTS: Seventy-five consecutive ML with or without AA patients anesthetized with dexmedetomidine and remifentanil infusions were identified, of which 74 (98.7%) also received concurrent propofol infusions. Mean duration of sedation was 190.9 ± 36.9 minutes and surgery was 139 ± 35.3 minutes. Transient hypopnea treated with supplemental oxygen complicated 18 (24%) cases and bradycardia requiring pharmacologic treatment complicated 3 (4%) cases. There were no other adverse anesthetic complications. One patient required surgical re-exploration due to postsurgical bleeding after the initial hospital discharge. CONCLUSION: In this cohort, a combination of remifentanil, dexmedetomidine and propofol infusions was well tolerated without serious adverse perioperative events.

Two-handed tying technique in vocal fold mucosa microsuture for the treatment of Reinke's edema.

BACKGROUND: Removal of Reinke's edema may result in moderate to large-sized mucosal defect on the vocal fold, which heals by secondary intention. Microsuturing this defect may lead to primary wound healing with fastened recovery and less scar, but costs extra time and effort. Exploring methods that can shorten microsuture time is helpful for the wider application of this technology. STUDY DESIGN: Retrospective. METHODS: 57 patients with Reinke's edema, who were admitted from November 2010 to June 2018, were enrolled as research subjects for the retrospective analysis. 27 patients were the knot pusher group (from November 2010 to March 2015), and 30 patients were the two-handed tying group (from April 2015 to June 2018). Evaluation indicators include the number of knots, the average time for suturing and tying the knot for each patient, and the occurrence of complications, subjective and objective voice assessments. RESULTS: All patients underwent successful operation. The average time for making knots in the knot pusher group and two-handed tying group was 668.40 ± 173.73 s and 328.73 ± 121.0 s, respectively, and there was a statistically significant difference between the two groups (p < 0.001). No significant difference was noted in the mucosal avulsion, overall incidence of complications between the groups, and no significant difference was found between the two groups in terms of the preoperative and 3-month postoperative subjective and objective indicators. CONCLUSION: Microsuturing of Reinke's edema microflaps using the two-handed tying technique can achieve the similar effect with the knot pusher method, and save operation time while the surgeon is well trained. LEVEL OF EVIDENCE: 4.

The Art and Craft of Phonomicrosurgery in Grammy Award-Winning Elite Performers.

BACKGROUND:: Since the renowned opera maestro Manuel Garcia presented "Observations on the Human Voice" using mirror laryngoscopy in 1855, there has been an inextricable link between performing vocalists and laryngologists. Today, specialized laryngeal surgeons continue the tradition of integrating medical and surgical management of performers with those skilled in vocal arts, voice science, and voice therapy. With advances in surgical instrumentation and techniques, increasing opportunities have evolved to surgically restore lost performing voices. However, it is especially challenging because of a range of factors, including the need for optimal technical precision, management of expectations, complexity of informed consent, public visibility of these patients, and the economics related to the success and failure of surgery. A number of these key issues apply to phonomicrosurgical procedures in nonsingers as well. Consequently, reviewing the art and craft of phonomicrosurgery in elite performers provides valuable insights into the optimal management of any patient. METHODS:: A retrospective review was done of microlaryngeal procedures for the past 20 years, and 18 elite performers were identified who were Grammy Award winners. Microsurgical methods for different lesions are illustrated. Composite analyses of the group along with their associated pathology was done to provide insights into key issues. RESULTS:: The 18 patients in this cohort have won 80 Grammy Awards, which were garnered from 242 nominations. All 18 had substantial deterioration in voice quality and could retain more than 1 pathology. Significant loss of superficial lamina propria (SLP) pliability was present in 15 of 18, varices and/or ectasias leading to vocal hemorrhage in 6, vocal polyps in 9, fibrovascular nodules in 6, arytenoid granuloma in 1, sulcus from prior microlaryngeal surgery leading to vocal fold SLP scarring in 4, sulcus from long-term phonotrauma leading to vocal fold SLP scarring in 4, benign cyst in 1, precancerous dysplasia in 2, and invasive carcinoma in 2. Subsequent to phonomicrosurgery, all reported improvement in their performance. CONCLUSIONS:: Laryngologists and laryngeal surgeons have shouldered a burden of responsibility for elite performing vocalists since the origin of our specialty. Most lesions and diagnoses that are encountered result from phonotrauma. Optimizing singers' care provides surgeons with extremely complex technical, emotional, social, and financial challenges. Focused analysis of managing elite performing vocalists effectively integrates a range of essential issues, which provide key insights to assist clinicians treating nonperforming patients requiring phonomicrosurgery.

Voice rest and sick leave after phonosurgical procedures: surveys among European laryngologists and phoniatricians.

PURPOSE: After surgery of vocal folds, almost every patient will need some voice rest. It is common to recommend total silence for some days, followed by less restricted voice use for variable periods. By now, we do not know how voice rest affects the healing process or the current practise in Europe. METHODS: Members of the European Laryngological Society (2012) and the Union of European Phoniatrics (2018) were sent a web-based questionnaire which included two patient cases with a short history and a still picture. The respondents were asked about the postoperative recommendation of absolute voice rest and sick leave. RESULTS: Over 90% of the respondents would recommend absolute voice rest after removing a polyp or after mucosal repair of Reinke's oedema. For both cases, the mean length of recommended absolute voice rest among UEP members was 4 days (range 0-10 days) and among ELS members was 5 days (range 0-14 days). The recommended sick leave ranged from 0 to 35 days. The mean figures suggested by ELS members for the receptionist with Reinke's oedema were 12 days and for the teacher with a polyp 13 days. On average, UEP members recommended 14 days of sick leave for both cases. CONCLUSION: The present scientific evidence is scant, but does not support for prolonged (over 3 days) absolute voice rest after simple phonosurgery. So far, there are no studies that could show absolute voice rest to be superior over relative voice rest. According to the present survey, there is considerable variation in recommending voice rest and sick leave after the removal of benign mucosal lesions. Many European laryngologists suggest voice rest that is longer and stricter than the present scientific literature supports.

Treatment Outcomes of Angiolytic Laser-Assisted Glottoplasty in Patients With Sulcus Vocalis.

OBJECTIVE: We have been performing glottoplasty using angiolytic laser, including pulsed dye laser (PDL) or potassium titanyl phosphate (KTP) laser, for the treatment of sulcus vocalis. In this study, we retrospectively reviewed the treatment results of sulcus vocalis patients who had undergone glottoplasty using angiolytic laser and evaluated the efficacy and safety of this surgical technique. METHODS: From January 2008 to April 2016, 79 patients with sulcus vocalis who underwent angiolytic LASER-assisted glottoplasty were enrolled in the study. RESULTS: Of the 79 patients who participated in this study, 55 were male, and 24 were female. PDL was used for glottoplasty in 68 patients, and KTP was used in the remaining 11 patients. Seventy-seven patients underwent surgery for bilateral vocal cord lesions, and only 2 patients underwent surgery for unilateral vocal cord lesion. After glottoplasty using angiolytic laser, most patients showed continuous improvement of the GRBAS (grade, roughness, breathiness, asthenia, strain) score and Voice Handicap Index score until 6 months after the operation. In addition, we observed improvement of objective voice indices such as noise to harmonic ratio, jitter, shimmer, and maximal phonation time postoperatively. CONCLUSIONS: Based on these results, we confirmed the efficacy and safety of glottoplasty using angiolytic laser in sulcus vocalis patients. Further studies are needed to confirm appropriate laser settings such as frequency of treatments and total energy delivered to the lesion. Also, multi-institutional studies are needed to confirm the efficacy and safety of the operation.
