ObjectiveThe purpose of this study was to evaluate epidemiologic characteristics of a treatment-seeking population referred to a private practice community voice clinic.Study DesignThis is a retrospective cohort study.MethodsPatient files representing evaluation referrals over a 28-month period were reviewed. Variables tabulated from records included disorder diagnosis, age, gender, perceptual voice quality ratings, and self-perceived voice handicap at initial evaluation. Descriptive statistics were used to evaluate the diagnosis category and demographic patterns. Parametric statistics were applied to quantitative clinical measurements to test the effect of voice disorder category on perceptual voice quality ratings and self-perceived voice handicap.ResultsA total of 216 consecutive patient files were reviewed. Collectively, the most common disorder diagnosis was "other," consisting of a varied cluster of etiologies, including reflux laryngitis, chronic cough, bilateral paralysis or paresis, leukoplakia, and polypoid degeneration. The most common diagnosis in women was midmembranous lesions, and that in men was the "other" category followed by atrophy and bowing associated with presbylaryngis. The greatest severity and handicap measures were found in patients with unilateral paralysis.ConclusionsCollectively, the demographic patterns reported in this study align with those from specialty voice clinics housed in academic medical centers and community voice clinics led by laryngologists and general otolaryngologists. Translating these findings to professional practice, the data support the notion that speech-language pathologists specializing as voice therapists who seek to establish private practice clinics should possess competencies in the knowledge and skills required to serve treatment-seeking populations with a wide variety of voice impairments.
