Voice Pathologies and the General Population's Perception.

OBJECTIVES: To examine how the general population perceives voice pathology based on subjective qualities. STUDY DESIGN: Descriptive, cross-sectional, survey-based study. METHODS: This is an IRB-approved Qualtrics survey on Amazon MTurk for respondents ages 18 and older. Ten subjects with voice pathologies supplied voice recordings of the Rainbow Passage to be assessed by the respondents. Respondents then assessed the voice conditions on perceived qualities of intelligence, leadership ability, and employability. One-way analysis of variance (ANOVA) and Dunnett's multiple comparison test with Sidak correction compared the mean scores of the samples (alpha = 0.05). RESULTS: A total of 1754 responses were included in the final dataset. The female control voice was scored as more likely to be a Fortune 500 leader as well as more intelligent, friendly, attractive, and employable when compared to the female vocal fry and muscle tension dysphonia (MTD) recordings (P < 0.0001). Conversely, the male MTD was the only male pathology that received a significantly lower score on friendliness, attractiveness, Fortune 500 leader status and employability than the male control (P = 0.0102, P = 0.0007, P = 0.0338, and P = 0.0039, respectively). CONCLUSIONS: This study demonstrates the more critical appraisal of voice pathologies of female patients compared to their male counterparts. People with voice disorders are perceived as being less successful, a disadvantage to potential leadership and career opportunities.

Predictors of voice therapy efficacy in vocal cord dysfunction at a tertiary care center.

OBJECTIVE: Vocal cord dysfunction is inappropriate adduction of vocal cords during inspiration that causes dyspnea and is commonly mistaken for exercise-induced asthma. To improve diagnostic accuracy, this study aims to identify demographics associated with vocal cord dysfunction and to determine their impact on the efficacy of voice therapy in improving vocal cord function. STUDY DESIGN: Retrospective chart review. SETTING: Single tertiary care institution between January 2015 and December 2021. METHODS: 184 patients who underwent voice therapy for vocal cord dysfunction were included. The primary outcome was patient self-reported percent improvement of symptoms. The secondary outcome was number of voice therapy treatments. RESULTS: The mean duration of symptoms was 2 ± 3 years. The mean number of voice therapy treatments was 2.2 ± 1.5. Of the 107 (58.2 %) patients with documented perceived breathing improvement percentages recorded, the mean maximal percent improvement was 72.5 ± 21.5 %. Mean maximal percent improvement of symptoms increased with each voice therapy treatment (p = 0.01). This association remained significant when controlling for comorbid conditions such as allergic rhinitis with postnasal drip, anxiety, asthma, and gastroesophageal reflux disease in multivariate analysis (p = 0.005). Patients with asthma had significantly higher maximum percent breathing improvement compared to those without asthma (p = 0.026). Similarly, patients who played sports had significantly higher maximum percent breathing improvement compared to those who did not (p = 0.022). CONCLUSION: Patient perceived breathing improvement with voice therapy is higher among those with concomitant asthma and those who play sports. Voice therapy is a safe and effective first line treatment of vocal cord dysfunction even when controlling for comorbid conditions.
