Duplication of the internal auditory canal is an uncommon, congenital malformation that can be associated with sensorineural hearing loss owing to aplasia/hypoplasia of the vestibulocochlear nerve. Only 14 such cases have been reported to date. We report the case of a 13-month-old girl with bilateral, congenital, sensorineural hearing loss caused by narrow, duplicated internal auditory canals and discuss the challenges encountered in the diagnosis and treatment of this condition.
