Background Vitiligo is the disappearance of functional melanocytes (MCs) from the involved skin by a mechanism(s) that has not yet been identified. Objective The aim was to study the effects of different types of vitiligo on cochlear function. Patients and methods This study involved 30 vitiligo patients who constituted the study group and 30 matched healthy individuals who served as the control group. Cochlear function was studied using pure-tone audiometry and transient-evoked otoacoustic emission. Results Normal pure-tone thresholds were found in vitiligo patients with no statistically significant difference between the control and vitiligo groups on both ears. There was a statistically significant difference between control and vitiligo groups as regards the signal-to-noise ratio at a frequency band of 4 kHz on both ears. Cochlear function is affected equally in both generalized and localized vitiligo subgroups. The duration of vitiligo does not have an effect on cochlear function.
