Abstract

This paper describes the abnormality of a large internal auditory meatus (LIAM). Computed tomography (CT) scans show the otic capsule to be affected by a widened, bulbar internal auditory meatus with loss of or reduction of the bony wall dividing the lateral fundus of the meatus from the cochlea. The vestibule is abnormally dilated. We report five cases of children with LIAM and profound hearing loss. Three of these children are girls and two children were boys. Three had congenital progressive hearing loss, one of these had an accompanying large vestibular aqueduct and dysplasia of the cochlea. Two patients had had meningitis resulting in profound loss.
