title: The relationship between dysphonia and sinusitis: a pilot study.
abstract: Though some clinicians believe chronic sinusitis is associated with dysphonia, studies confirming such a relationship are not available. This pilot study investigated vocal characteristics of chronic sinusitis patients compared to those of nonsinusitis patients. Nineteen male patients were evaluated in a single-blind, nonrandomized, prospective study at a Department of Veterans Affairs Medical Center. After candidates for the experimental and control groups were thoroughly screened [nasal and laryngology examinations, sinus computed tomography (CT) scan, history], 10 chronic sinusitis patients were assigned to the experimental group, nine patients without chronic sinusitis were assigned to the control group. Visi-Pitch analysis of their speech evaluated fundamental frequency, intensity, and perturbation. The evaluator described voice quality and vowel prolongation. Videostroboscopic examination evaluated glottic closure, supraglottic activity, vocal fold edge, amplitude, mucosal wave, and nonvibrating portion. Visi-Pitch analysis and vowel prolongation for each group was compared using an independent t-test. The average fundamental frequency mean was 113.43+/-32.75 Hz for the control group and 112.29+/-19.71 for the experimental group. This study established methods and parameters to determine if a relationship between chronic sinusitis and dysphonia actually exists. It did not establish a relationship between these entities, possibly due to the small sample size enrolled in the study, but determined that 126 subjects would be necessary to achieve significant results.
