J Voice 2024:S0892-1997(24)00080-8. [PMID: 38556378 DOI: 10.1016/j.jvoice.2024.03.006] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/20/2024] [Revised: 03/09/2024] [Accepted: 03/11/2024] [Indexed: 04/02/2024]
Abstract
OBJECTIVES This study aimed to provide a comprehensive overview of the systematic reviews that focus on the prevalence of voice disorders (VDs), associated risk factors, and the demographic characteristics of patients with dysphonia. An umbrella review was conducted to identify general research themes in voice literature that might guide future research initiatives and contribute to the classification of VDs as a worldwide health concern. STUDY DESIGN Umbrella review of systematic reviews. METHODS Pubmed/Medline and Embase were searched for eligible systematic reviews by two authors independently. Extracted data items included the study publication details, study design, characteristics of the target population, sample size, region/country, and incidence and/or prevalence of the VD(s) of interest. RESULTS Forty systematic reviews were included. Sixteen reported a meta-analysis. Great heterogeneity in methods was found. A total of 277,035 patients across the included studies were included with a prevalence ranging from 0%-90%. The countries represented best were the United States and Brazil, with 13 studies each. Aging, occupational voice use, lifestyle choices, and specific comorbidities, such as obesity or hormonal disorders, seem to be associated with an increased prevalence of dysphonia. CONCLUSIONS This review underscores the influence of VDs on distinct patient groups and the general population. A variety of modifiable or non-modifiable risk factors, having varied degrees of impact on voice qualities, have been identified. The overall effect of VDs is probably underestimated due to factors, such as sample size, patient selection, underreporting of symptoms, and asymptomatic cases. Employing systematic reviews with consistent methodologies and criteria for diagnosing VDs would enhance the ability to determine the prevalence of VDs and their impact.

J Voice 2023:S0892-1997(23)00348-X. [PMID: 38155057 DOI: 10.1016/j.jvoice.2023.10.027] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/31/2023] [Revised: 10/18/2023] [Accepted: 10/19/2023] [Indexed: 12/30/2023]
Abstract
OBJECTIVE To map the volitional and non-volitional devices used by speech and language pathologists (SLPs) in voice training and therapy and characterize their use in research on voice interventions. METHODS This scoping review is the first part of a larger study. The electronic search was carried out by mapping the references in PubMed/Medline, LILACS/BVS, Scopus, Web of Science, EMBASE, and the Cochrane Library, and the manual search was carried out in the grey literature. Two blind independent reviewers selected and extracted data; divergences were solved by consensus. The data extracted in this part of the study were the authorship and year of publication, country, study design, sample characteristics, intervention modality, ingredient, target, mechanism of action, dosage, and outcome measures. They were addressed with descriptive analysis. RESULTS Publications that use devices as ingredients are mostly from the last two decades, mainly carried out in the United States of America and Brazil, in adults of both sexes with behavioral dysphonia. Forty-two types of devices were used, many of them with similar approaches but different nomenclatures. Most devices were used voluntarily, focusing on vocal function, and aiming to increase source and filter interaction. Most studies used silicone tubes. The most reported technical specification to apply the ingredient was surface electrodes on the neck. Device dosage was time-controlled, and the most used outcomes were self-assessment and acoustic analysis. CONCLUSION Devices are currently used as ingredients in vocal interventions, with a greater focus on increasing the source and filter interaction, associated with silicone tubes (the most used devices in these studies), which have been dosed with performance time. Outcomes were measured with self-assessment instruments.

[PMID: 37648624 DOI: 10.1016/j.jvoice.2023.07.024] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/24/2023] [Revised: 07/25/2023] [Accepted: 07/26/2023] [Indexed: 09/01/2023]
Abstract
INTRODUCTION Past studies show that performers are more susceptible to voice injury, have higher incidence of injury, and experience greater vocal impairment than non-performers. Despite literature demonstrating otherwise, there remains fear and stigma that voice injury is a career-ending circumstance. Much of this is due to a lack of information about post-treatment vocal function. METHODS An anonymous online survey was distributed via email, flyer, and social media to a target audience of performers with a history of voice injury. It inquired about occupation, vocal symptoms, professionals consulted, and treatment adherence. Outcome measures included ability to perform, resolution of symptoms, and attitudes about their voices after voice injury. Findings were analyzed descriptively with statistical analysis to determine factors that may be related to favorable outcomes. RESULTS The survey was completed by 151 performers representing a range of genres, including musical theatre, classical, and popular genres. The most reported vocal symptoms were decreased range, singing voice quality changes, increased singing effort, and vocal fatigue. Most initially sought care from an otolaryngologist, laryngologist, or voice teacher. Diagnoses and recommendations varied, but those who adhered to treatment were more likely to report resolution of voice symptoms (P = 0.025). Those with symptoms for 2-4 weeks reported greater vocal confidence than those with a longer symptom duration (P = 0.0251). Performers working with a voice teacher were more likely to find treatment helpful (P = 0.0174). Those with neurogenic voice conditions reported less vocal reliability than participants with other pathologies (P = 0.0155). CONCLUSION The majority of participants continued to perform, reported resolved or improved voice symptoms after treatment, and reported positive attitudes about their voices, regardless of their injury or current presence or absence of pathology on exam. Findings of this study highlight a need for continued outreach to voice teachers, education programs, and production teams about vocal function after voice injury. LEVEL OF EVIDENCE: 4

Abstract
OBJECTIVES/HYPOTHESIS To determine if (1) the likelihood of presenting with phonotraumatic lesions differs by singing genre in treatment-seeking singers and (2) if the distribution of phonotraumatic lesion types differs by singing genre. STUDY TYPE Retrospective. METHODS Records of singers who presented with a voice complaint over the course of 2.5 years (June 2017-December 2019) were reviewed to determine the proportion of those with phonotraumatic lesions as a function of genre (Study 1). Separately, the lesion types and genres of singers diagnosed with phonotraumatic lesions over a 9-year period (July 2011-March 2020) were determined (Study 2). RESULTS In Study 1, 191 of 712 (26.8%) dysphonic singers were diagnosed with phonotraumatic lesions. Country/folk, gospel/jazz, and musical theater singers were more likely to present with phonotraumatic lesions. In Study 2, in 443 singers with phonotraumatic lesions, polyps and pseudocysts, but not nodules, were found to be distributed unequally across genres (χ2 p = 0.006, p < 0.0001, p = 0.064, respectively). Praise/worship singers had significantly higher proportions of polyps compared to choral singers (OR 4.8 [95% CI 1.9-12.5]) or compared to musical theater singers (OR 7.2 [95% CI 2.5-20.8]). Opera singers had significantly higher proportions of pseudocysts than choral singers (OR 3.1 [95% CI 1.5-6.1]) or musical theater singers (OR 3.7 [95% CI 1.8-7.6]). CONCLUSIONS The higher incidence of polyps in praise/worship singers likely reflects the more emphatic nature of singing and the tendency for acute injury. The higher incidence of pseudocysts in opera singers may reflect a more chronic nature of injury. LEVEL OF EVIDENCE 4 Laryngoscope, 2023.

JOURNAL OF SPEECH, LANGUAGE, AND HEARING RESEARCH : JSLHR 2022; 65:2778-2788. [PMID: 35914023 PMCID: PMC9911101 DOI: 10.1044/2022_jslhr-21-00658] [Citation(s) in RCA: 4] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Grants] [Track Full Text] [Subscribe] [Scholar Register] [Received: 12/13/2021] [Revised: 04/07/2022] [Accepted: 05/02/2022] [Indexed: 06/15/2023]
Abstract
PURPOSE This study aimed to determine whether a simplified, and potentially more stable, acoustic-aerodynamic voice outcome ratio (ratio of sound pressure level [SPL] to subglottal pressure) is comparable to a traditional vocal efficiency measure (ratio of acoustic power to the product of average subglottal pressure and average phonatory airflow) in terms of the ability to detect change in vocal function following surgical removal of bilateral phonotraumatic lesions. METHOD Pre- and postoperative acoustic and aerodynamic measures were analyzed retrospectively from 75 female patients who underwent surgical removal of bilateral phonotraumatic lesions. A 2 × 2 repeated-measures analysis of variance was conducted for each of three acoustic-aerodynamic voice outcome ratios-traditional vocal efficiency, an SPL-based ratio with both airflow and subglottal pressure, and a simplified SPL-based ratio with subglottal pressure only-to investigate the main effects of treatment stage (pre- and postsurgery), loudness condition (comfortable and loud), and their interaction. Post hoc paired samples t tests were conducted for statistically significant interactions. The within-subject variability of the measures was assessed using the coefficient of variation. RESULTS Although exhibiting an expected main effect of loudness (higher values in the loud condition), the traditional vocal efficiency ratio did not exhibit a main effect of treatment. For both SPL-based ratios, there were significant main effects of treatment stage (higher values postoperatively) and loudness condition (lower values in the loud condition). Within-subject, postoperative changes in the two SPL-based ratios moderately correlated with one another. The simplified ratio of SPL to subglottal pressure (without airflow) exhibited the least within-subject variability relative to the other two acoustic-aerodynamic ratios. CONCLUSIONS These findings indicate that SPL-based acoustic-aerodynamic voice outcome ratios increase significantly following the surgical removal of phonotraumatic vocal fold lesions. The simplified ratio of SPL to subglottal pressure exhibits the least variability and can be easily obtained without requiring the measurement of airflow.

Abstract
OBJECTIVES/HYPOTHESIS Voice therapy is a mainstay treatment modality in the management of phonotrauma in singers. However, the typical duration of therapy an injured singer undergoes is unknown. The primary aims of the study were to determine (1) the number of therapy sessions preceding a decision for surgery and (2) the number of sessions and length of time to achieve improvement in singers who did not undergo surgery. Whether specific singer factors were associated with the length of therapy was also investigated. STUDY DESIGN Retrospective. METHODS Records of singers with phonotraumatic vocal fold lesions seen over a 9-year period at a tertiary care voice center were reviewed. RESULTS Sixty singers who underwent surgery and 183 singers who did not undergo surgery were included in the final analysis. In nearly ¾ of the surgical patients, five or fewer voice therapy sessions were completed prior to the decision for surgery. Singers who did not undergo surgery required on average 3-4 sessions before noting improvement. Over 60% of the non-surgical singers improved within 3 months and 84% were judged to be improved by 6 months. Lesion type, professional/amateur status, formal voice training, and having a current voice teacher/coach were not associated with the length of voice therapy. CONCLUSIONS The length of voice therapy prior to decision for surgery was limited, and so was the length of therapy leading to initial improvement in singers who did not require surgery. These findings provide a framework for voice therapy expectations and could be reassuring for this unique population.
