Lateral semicircular canal dilatation in a patient with congenital hearing loss due to α-tectorin mutation: microanatomical considerations.

Abstract excerpt

The tectorial membrane is crucial in the physiology of the auditory neuroepithelium. Mutations in one of its functional molecules, α-tectorin, lead to autosomal dominant and recessive congenital mid-frequency, non-syndromic hearing loss.Typically, α-tectorin mutations are not accompanied by any morphological abnormalities of the labyrinth. For the first time, we present a case of a toddler boy with congenital...
