| Popis: | OBJECTIVES To evaluate differences in vocal motor control and central auditory processing between treated unilateral vocal fold paralysis (UVFP) and healthy control cohorts. STUDY DESIGN Cross-sectional. METHODS Ten UVFP study patients treated by type I thyroplasty with stable voices were compared to 12 control subjects for vocal motor control using a pitch perturbation response task and central auditory processing performance using a battery of complex sound intelligibility assays that included adverse temporal and noise conditions. Standard clinical evaluations of voice production and peripheral audiometric sensitivity were performed. RESULTS Vocal motor control was impaired in treated UVFP. The UVFP cohort exhibited a 32.5% reduction in the instantaneous, subconscious compensatory response to pitch feedback perturbation in the interval between 150 ms and 550 ms following onset (P |
