Abstract
The larynx undergoes significant age and sex-related changes in structure and function across the lifespan. Emerging evidence suggests that laryngeal microbiota influences immunological processes. Thus, there is a critical need to delineate microbial mechanisms that may underlie laryngeal physiological and immunological changes. As a first step, the present study explored potential age and sex-related changes in the laryngeal microbiota across the lifespan in a murine model. We compared laryngeal microbial profiles of mice across the lifespan (adolescents, young adults, older adults and elderly) to determine age and sex-related microbial variation on 16s rRNA gene sequencing. Measures of alpha diversity and beta diversity were obtained, along with differentially abundant taxa across age groups and biological sexes. There was relative stability of the laryngeal microbiota within each age group and no significant bacterial compositional shift in the laryngeal microbiome across the lifespan. There was an abundance of short-chain fatty acid producing bacteria in the adolescent group, unique to the laryngeal microbiota; taxonomic changes in the elderly resembled that of the aged gut microbiome. There were no significant changes in the laryngeal microbiota relating to biological sex. This is the first study to report age and sex-related variation in laryngeal microbiota. This data lays the groundwork for defining how age-related microbial mechanisms may govern laryngeal health and disease. Bacterial compositional changes, as a result of environmental or systemic stimuli, may not only be indicative of laryngeal-specific metabolic and immunoregulatory processes, but may precede structural and functional age-related changes in laryngeal physiology.

Abstract
OBJECTIVE Decision-making regarding behavioral versus procedural intervention in the treatment of presbyphonia has not been well defined. The study objective was to survey laryngologists' reported practice patterns and decision-making in presbyphonia. METHODS All laryngology faculty in U.S. academic medical centers with residency programs were recruited to complete an anonymous 29-item survey regarding decision-making in presbyphonia treatment. The survey included 5 sections: demographics, first-line treatment distribution, factors that drive decision-making toward procedural intervention, treatment progression if first-line treatment is insufficient, durable treatment. RESULTS Of 153 laryngologists surveyed, 89 responded (58%). Voice therapy (VT) was the most often reported first-line treatment, with 57% of respondents indicating the majority of their patients receive VT initially. Most respondents (83%) indicated they occasionally use procedural intervention as first-line treatment. Factors driving first-line procedural intervention were severe glottal insufficiency (87%), high occupational/social voice demands (76%), voice not stimulable for change (73%), difficulty attending VT (70%), severe dysphonia (65%), and dysphagia (61%). The majority of respondents indicated the following do not affect their decision to pursue procedural intervention: patient age (88%); medical comorbidities (63%); patient's desire for a "quick fix" (55%); patient-reported outcome measures (51%). Most respondents (81%) use trial injection augmentation before durable treatment. Of durable treatments, bilateral thyroplasty was preferred (71%), followed by CaHA (15%) and lipoinjection (11%). CONCLUSIONS This study is the first to our knowledge to examine factors that influence decision-making in presbyphonia treatment. While VT remains the most frequent first-line treatment, study results better inform decision-making regarding first-line procedural intervention.

Abstract
OBJECTIVE Age-related vocal atrophy (ARVA) can dramatically affect voice, communication, and quality of life. The objectives of this systematic review were to (1) determine whether treatments for ARVA were superior to controls (2) compare the relative efficacy of procedural and behavioral treatments (3) review the various types of outcome measures, and (4) evaluate the quality of studies. REVIEW METHODS The literature was searched using strategies designed by a medical librarian (2/18/21, updated 3/9/22). Studies investigating treatments for bilateral vocal atrophy were included. Studies involving unilateral atrophy, presbyphonia (without endoscopic findings), or an absent comparator group were excluded. The Preferred Reporting Items for Systematic Reviews and Meta-analyses checklist was used to guide this study. RESULTS After applying the inclusion/exclusion criteria, 8 articles remained, including 4 randomized trials and 4 cohort studies, and a narrative synthesis was performed. Surgical and behavioral treatments for ARVA appeared to be superior to control groups, based on specific outcome measures. However, the superiority of these treatments over controls was not uniformly observed across multiple outcome measures. When comparing different treatments, superiority could not be established based on the quality and completeness of the studies included in the systematic review. Outcome measures also varied between individual studies. Finally, the risk of bias was analyzed and scored. Consistent point deductions among reviewed studies were noted. CONCLUSIONS When comparing treatments for ARVA. Surgery and voice therapy were both superior to control groups based on specific outcome measures from different domains. Superiority of one treatment could not be established. LEVEL OF EVIDENCE N/A Laryngoscope, 133:2846-2855, 2023.

[PMID: 37423795 DOI: 10.1016/j.jvoice.2023.05.010] [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: 04/18/2023] [Revised: 05/17/2023] [Accepted: 05/17/2023] [Indexed: 07/11/2023]
Abstract
OBJECTIVE The primary objective of this study was to assess objective voice measures in an elderly population representative of those seen in a tertiary laryngology practice, stratified by sex and presbylarynx status, and compare their measures to each other and to a cohort of young adult patients aged 40 years or less. The secondary objectives of this study were to evaluate and compare the strobovideolaryngoscopy findings across all groups and compare the voice complaints and subjective questionnaire results between the presbylarynx and non-presbylarynx groups. METHODS Two hundred and eighty-six adult voice patients (147 females/139 males) were included in this study and stratified into one of three groups: (1) young adults aged 40 years or less (n = 122), (2) patients over the age of 60 without presbylarynx (n = 78), and (3) patients over the age of 60 with a diagnosis of presbylarynx (n = 86). The acoustic analysis included fundamental frequency (F0), voice intensity, standard deviation of the fundamental frequency (SDFF), jitter (Jitt), relative average perturbation (RAP), shimmer (Shim), noise-to-harmonic ratio (NHR), and others. The aerodynamic and pulmonary assessment included maximum phonation time (MPT), S/Z ratio, mean flow rate (MFR), forced expiratory volume in 1 second (FEV1), and maximal mid-expiratory flow (FEF25-75). Coexisting vocal fold conditions and pathologies were also characterized and compared. Statistical analysis was performed using SPSS 28.0.0.0 (IBM, Armonk, NY). All tests were performed in two-tailed, and a P value of less than 0.05 was considered statistically significant. RESULTS Assessment of vocal fold features revealed a significantly higher prevalence of benign vocal fold lesions in the young adult group for males and females compared to both elderly groups but significantly lower prevalence of vocal fold edema only in young adult females compared to the elderly female groups. Among males, young adults differed significantly from both elderly groups with regard to SDFF, Shim, FEV1, and FEF25-75. However, Jitt and RAP only differed significantly between the young adult and presbylarynx groups. Among females, young adults differed significantly from both elderly groups for F0, SDFF, Jitt, RAP, NHR, CPP, MFR, FEV1, and FEF25-75. However, the non-presbylarynx group had a significantly lower S/Z ratio than the young adult and presbylarynx groups. A comparison of voice complaints between elderly groups revealed breathiness to be significantly more common in the presbylarynx group compared to the non-presbylarynx group, but no other significant differences were found in voice complaints or questionnaire scores. CONCLUSION When interpreting objective voice measures, it is critical to consider differences in vocal fold features alongside age-related changes. In addition, sex-related differences in anatomy and the aging process may explain discrepancies in significant findings between young adults and elderly patients stratified by presbylarynx status. However, presbylarynx status alone appears insufficient to generate significant differences in most objective voice measures among the elderly. Yet, presbylarynx status may be sufficient to generate differences in perceptual voice symptoms.

Abstract
Cepstral measures are sensitive to gender, age and phonatory tasks. With a cepstral measure designated as the CPP, it was possible to confirm the vulnerability of the Fado singers' voice. These were established at the vocal pathological threshold, which suggests a need for a direct clinical approach for these voice users. OBJECTIVES/HYPOTHESIS This study aimed to characterize cepstral peak prominence (CPP) and cepstral peak prominence smoothed (CPPS) in the Fado singing voice and to determine if there were significant differences in CPP and CPPS measures between spoken and sung tasks, as well as due to singers' gender and age. METHODS Forty seven males and 57 females Fado singers, ranging from 18 to 70 years participated in this study. Spoken voice tasks were sustained [a] and reading aloud the phonetically balanced text "O Sol". Sung tasks were sustained [a] of the word [ɐfinaɫ] and the Fado chorus song "Nem às paredes confesso". Acoustic measures included CPP and CPPS. CPP was measured using Analyses of Dysphonia in Speech and Voice software, of Multi-Speech program, Model 3700, by KayPENTAX. CPPS was measured using Praat software (4.2.1/2003). Statistical analysis was performed with an IBM SPSS Statistics version 22 program. CPP and CPPS mean differences of spoken and sung tasks were analyzed using paired samples t-test, with α at .05. RESULTS CPP and CPPS values of singers' voice changed according to the gender, age and phonatory tasks. There were significant differences between CPP and CPPS measures (P < 0.05). Generally, young male singers, in their sung task, presented the highest CPP and CPPS values. The highest CPP mean was obtained by older males in sustained spoken [a] and the lowest was obtained by younger males in their reading aloud task. For CPPS, the highest mean value was obtained by younger males during sung [a] and the lowest was by younger males in the reading aloud task. CONCLUSION Males presented higher cepstral measures than females. Young singers presented higher cepstral measures than older. Sung tasks had higher cepstral measures than spoken tasks. CPPS means are overall higher than CPP means. This study reinforces the need for a clinical prevention approach directed at potential vocal disorders in Fado singers.

Abstract
PURPOSE The purpose of this study was to use objective measures of glottal gap, bowing, and supraglottic compression from selected images of laryngoscopic examinations from adults over 60 years of age with voice complaints and signs of aging to test current hypotheses on whether degree of severity impacts treatment recommendations and potential follow-through with treatment. METHOD Records from 108 individuals 60 years or older with voice complaints and signs of aging were reviewed. Three objective measures (normalized glottal gap area [NGGA], total bowing index, and normalized true vocal fold width) were derived. Each measure was subsequently divided into three categories by severity: absence, small degree, or large degree. Nonparametric statistics tested associations between severity and treatment recommendations as well as potential follow-through. RESULTS Noninvasive treatments (observation/voice therapy) were marginally associated with no glottal gap (p = .09). More invasive treatments (injection/bilateral thyroplasty) were associated with glottal gaps being present (p = .026), but bilateral thyroplasty recommendations were not significantly associated with the largest gaps. Treatment modalities were not characterized by specific severity categories for any of the objective measures. No significant differences were found for any of the three objective measures between those who followed through with recommended treatment and those who did not. DISCUSSION Results demonstrated some support for current hypotheses on how degrees of severity of objective measures relate to treatment recommendations. Of the three measures, NGGA appears to be more informative regarding treatment recommendations and follow-through, but due to low power, larger sample sizes are needed to confirm clinical relevance.

Abstract
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.

Abstract
OBJECTIVES The objective of this study was to determine the prevalence of voice handicap perception of teachers in Kuwait and compare them within the general population by using the validated Arabic version of the voice handicap index-10 (VHI-10). Moreover, we explored variations within the teaching profession itself with regards to specific characteristics. METHODS The study was a cross-sectional survey design, in which participants from all governates of Kuwait (1820 teachers and 755 controls) completed the validated Arabic VHI-10, health-related, and demographic questions. The questionnaires were distributed among a random sample of elementary, middle, and high school teachers of both genders, and a random sample of the control population. RESULTS The mean VHI-10 of teachers was significantly higher than nonteachers (mean VHI-10 of teachers = 5.7, mean VHI-10 of nonteachers = 3.7, P < 0.001). Furthermore, there was a significant difference between teachers and controls in those who scored >11 in the VHI-10 (>11 = 17.6%, 10.2% respectively, P = <0.001). Female teachers scored a higher mean VHI-10 than male teachers (B = 0.66, P < 0.001). There was no difference in the mean VHI-10 among the different teaching class levels. However, elementary school teachers were the most group to exceed the cut-off point (VHI-10 >11) (Odds Ratio = 1.38, P = 0.04). With regards to smoking, we found no difference in the mean VHI-10 and scoring >11 in the questionnaire. Art and science teachers had the highest mean VHI-10 (P = 0.005 and 0.03, respectively). CONCLUSION The results of the study revealed a higher perception of voice handicap in teachers than nonteachers. Therefore, emphasis should be on teachers in order to prevent voice damage.

Abstract
Purpose To evaluate voice outcome after bilateral medialization thyroplasty in patients with non-paralytic glottic insufficiency due to vocal fold atrophy with or without sulcus. Methods Retrospective cohort study on 29 patients undergoing bilateral medialization thyroplasty for vocal fold atrophy (14 procedures) or atrophy with sulcus (15 procedures) between October 2012 and November 2017. Voice data were collected and analyzed for the preoperative and the 3- and 12-month postoperative time point according to a standardized protocol, including Voice Handicap Index (VHI)-30 and perceptual, acoustic and aerodynamic parameters. Failure rate was based on number of revisions within 12 months and non-relevant improvement (< 10 points) in VHI-30 at 12 months. Results There was a clinically relevant (≥ 15 points) and statistically significant improvement (p < 0.0001) in the VHI-30 (preoperative: 55.8 points; postoperative at 12 months: 30.9 points). Fundamental frequency for male subjects decreased significantly from 175 to 159 Hz (p = 0.0001). The pre- and post-operative grade of dysphonia was significantly lower in patients with atrophy compared to atrophy and sulcus (mean difference 0.70, p = 0.017). Conclusion Bilateral medialization thyroplasty is a valid treatment option for patients with atrophy with or without sulcus. Outcomes are comparable to other methods reported in literature. However, there is a great need for larger, prospective studies with long-term follow-up to gain more insight into the comparative voice outcomes for the different forms of surgery for patients with glottic incompetence due to atrophy with or without sulcus.

Abstract
The alterations of the extracellular matrix (ECM) in lamina propria of the vocal folds are important changes that are associated with decreased vibrations and increased stiffness in aging vocal fold. The aim of this study was to investigate the differences in gene expression of lamina propria using next generation sequencing (NGS) in young and aging rats and to identify genes that affect aging-related ECM changes for developing novel therapeutic target molecule. Among the 40 genes suggested in the NGS analysis, voltage-gated calcium channels (VGCC) subunit alpha1 S (CACNA1S), VGCC auxiliary subunit beta 1 (CACNB1), and VGCC auxiliary subunit gamma 1 (CACNG1) were increased in the lamina propria of the old rats compared to the young rats. The synthesis of collagen I and III in hVFFs decreased after si-CACNA1S and verapamil treatment. The expression and activity of matrix metalloproteinases (MMP)-1 and -8 were increased in hVFFs after the treatment of verapamil. However, there was no change in the expression of MMP-2 and -9. These results suggest that some calcium channels may be related with the alteration of aging-related ECM in vocal folds. Calcium channel has promising potential as a novel therapeutic target for the remodeling ECM of aging lamina propria.

Abstract
Objectives (1) Characterize the US population aged ≥65 years with self-reported voice problems, (2) describe voice treatment characteristics in this group, and (3) identify factors associated with self-reported voice improvement. Study Design Retrospective cohort study. Setting Population-based cross-sectional US national survey sample. Subjects and Methods We identified a cohort of adults aged ≥65 years from the 2012 National Health Interview Survey, a population-based US national survey. Descriptive and multivariable regression analyses were performed. Results The prevalence of self-reported voice problems in this cohort was 10%. Of those, 44% reported voice problems for >1 month. The strongest predictor of reporting voice improvement was receipt of voice treatment (odds ratio, 3.50; 95% confidence interval, 1.36-9.00), after adjusting for sex, age, race, education, and health status. Eleven percent reported voice treatment, which included 20% of those with moderate or worse voice problem severity. Female sex and worse health status were associated with reporting voice treatment. Among those with voice treatment, 38% reported “better,” 33% “same,” and 29% “worse” voice symptoms over the past year, compared to 17%, 67%, and 16%, respectively, among those without treatment. Health status influenced likelihood of reporting voice improvement but not universally. Conclusions We observed a significant self-reported burden of voice problems in the US population aged ≥65 years. Most are untreated and thus not well represented in the current literature. Vocal improvement was strongly associated with treatment. Further investigation is needed to clarify patient and treatment characteristics most associated with vocal improvement.

[PMID: 29373176 DOI: 10.1016/j.jvoice.2017.10.017] [Citation(s) in RCA: 3] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/27/2017] [Revised: 10/18/2017] [Accepted: 10/19/2017] [Indexed: 11/25/2022]
Abstract
OBJECTIVE Trial vocal fold injection (TVFI) is employed diagnostically for patients with subtle glottic insufficiency to explore potential for improvement. Clinical experience demonstrates the time to and length of peak benefit of the TVFI is variable. Previous studies collected data 4 weeks or more after TVFI. The aim of this study was to compare subjectively successful and unsuccessful TVFI patient groups. It is hypothesized that patients with subjectively reported success will also have significant improvements in Voice Handicap Index-10 (VHI-10), phase closure percentage, and aerodynamic measures 2 weeks after trial augmentation. METHODS/DESIGN Subjects with glottic insufficiency were included in this retrospective review if they underwent office-based, per-oral vocal fold injection augmentation specifically for trial purposes. Patients were divided into "successful" and "unsuccessful" groups based on their subjective experience during the 2-week post-TVFI period. VHI-10, subjective report, phase closure evaluation using frame-by-frame analysis, and aerodynamic data were collected pre- and 2 weeks post-TVFI. RESULTS Of the subjects, 15 of 23 (65%) reported a successful subjective improvement of their symptom, whereas 8 (35%) were unsuccessful (only partial improvement or no improvement). The number of subjects with an improvement in VHI-10 by 5 or more points was not significantly different between groups. The number of subjects that demonstrated complete, long phase closure was significantly higher in the successful group (P = 0.021). CONCLUSIONS The understanding of how to more precisely determine the success of TVFI remains incomplete. Subjective improvement of successful TVFI was captured with basic clinical questioning, yet the VHI-10 was unable to confidently demonstrate this reported success 2 weeks after TVFI.
