Waardenburg syndrome (WS) is a rare hereditary autosomal dominant disorder which is characterized by congenital neurosensorial hearing loss with various phenotypic features. In this study, we described 4 patients with WS who had hearing loss. Bilateral hearing loss, hair and iris pigmentation disorder were presented in all patients, and leucoderma was detected in one patient. Other systemic examinations of the patients revealed no pathological findings. To improve the quality of life, appropriate hearing aids was recommended by measuring hearing levels.
