title: Congenital cholesteatoma of external auditory canal.
abstract: A 7-month-old male child is reported with congenital cholesteatoma of the external auditory canal. We describe the clinical features, computed tomography finding and surgical treatment. Congenital cholesteatomas can occur within the temporal bone. There are six places of location: (1) petrous apex, (2) mastoid, (3) middle ear, (4) both middle ear and mastoid, (5) external ear canal and (6) within the squamous portion of the temporal bone. Congenital cholesteatoma of the external auditory canal is rare. Generally, it appears in the canal floor without lesions in the tympanic membrane. Computed tomography completes the study. Treatment consists of excision of the mass.
