Background and Objectives: Professional voice users (PVUs) are individuals for whom the voice is the primary tool of work, and whose professional success and income largely depend on its quality. This paper’s study population predominantly consisted of occupational voice users with moderate vocal demands and the study aimed to identify risk factors and causes of voice quality and production disorders, as well as the socio-epidemiological characteristics of affected patients. Materials and Methods: A retrospective study was conducted in Serbia, including 145 occupational voice users aged 20–70 years who were treated for dysphonia between August 2019 and July 2024. Data collected included demographics, symptom duration, tobacco exposure, throat and nasal swab results, gastroenterological and endocrinological evaluations and information on treatment for allergic rhinitis, asthma, and dysphonia. Patients were stratified by age, profession, and cause of dysphonia into the appropriate groups. Results: Dysphonia is significantly more common among female occupational users. There is a significant association between the cause of dysphonia and both age and hyperthyroidism. Smoking was highly prevalent in the study population and showed associations with selected videolaryngostroboscopic parameters; however, causal inferences could not be made due to the lack of a non-smoking comparison group. No statistically significant association was observed between positive nasal or throat swabs and dysphonia, nor between allergic rhinitis or asthma and the onset of dysphonia in occupational voice users. Treatment modality varies by gender, with male occupational voice users more likely to undergo surgery and female occupational voice users more often receiving conservative therapy. Symmetric vocal fold vibrations were observed in 85.5% of participants, while regular vibrations were present in 53.1%, and insufficient glottal closure in 10.3%. Regular vocal fold vibration was significantly less frequent in patients with structural disorders and more common in individuals aged 30–39 years. Male sex showed a borderline association with reduced likelihood of symmetric vocal fold vibrations. No independent predictors of insufficient glottal closure were identified. Conclusions: These results support the implementation of systematic otolaryngologic examinations, combined with mandatory education on proper voice use, vocal hygiene, and the harmful effects of tobacco smoke, as measures to prevent voice disorders in occupational voice users.

Background and Objectives: This study examined changes in hearing handicap and quality of life following hearing amplification in older adults and associations of hearing aid outcomes and healthcare communication satisfaction with post-amplification quality of life. Materials and Methods: This prospective, multicenter study included 117 adults aged over 60 years with bilateral severe sensorineural hearing loss and no previous hearing aid use. Hearing handicap, quality of life, hearing aid outcomes, and healthcare communication satisfaction were assessed using the Hearing Handicap Inventory for the Elderly (HHIE), WHOQOL-BREF, International Outcome Inventory for Hearing Aids (IOI-HA), and a 12-item communication satisfaction measure, respectively. Results: Hearing amplification was associated with significantly reduced hearing handicap and improved quality of life across all WHOQOL-BREF domains (p < 0.01). Healthcare communication satisfaction also improved significantly (p < 0.001). Better hearing aid outcomes were associated with higher post-amplification quality of life across all domains, remaining independently associated after adjustment for baseline quality of life and participant characteristics. Greater healthcare communication satisfaction was positively associated with all quality-of-life domains but remained independently associated only with social relationships after adjustment. Conclusions: Hearing amplification was associated with reduced hearing handicap, improved quality of life, and greater healthcare communication satisfaction. Better hearing aid outcomes were independently associated with higher quality of life across all domains, whereas communication satisfaction was independently associated only with social relationships. This finding warrants caution given the lower internal consistency of that domain.
