Background: Waardenburg Syndrome (WS) is an autosomal-dominant disorder, characterized by sensorineural hearing loss and pigmentary abnormalities of the eyes, hair, and skin. Auditory-pigmentary syndromes are caused by physical absence of melanocytes from the skin, hair, eyes, and the stria vascularis of the cochlea. Purpose: To provide information regarding clinical manifestation of Waardenburg Syndrome for early detection and prompt treatment particularly for hearing impairments. Case: A 7-year-old boy with late detection of hearing impairment. Previously, his parents didn’t recognize that this condition was one manifestation of Waardenburg syndrome, so that this patient developed speech delay. Method: Searching for evidence produced 14 journals and only 2 journals were relevant. Result: Of the 2 relevant journals, there were 1 research article and 1 case report that explained several clinical manifestations of Waardenberg Syndrome. Conclusion: Early detection and management of hearing impairment as one of frequent clinical manifestation of Waardenberg Syndrome is significantly important since this condition could influence patient’s individual and social developments.
