Clinical characteristics of patients with narrow bony cochlear nerve canal

Abstract

Narrow bony cochlear nerve canal is not likely to have a simple Mendelian inheritance pattern, especially in unilateral cases. The contribution of a Mendelian genetic etiology to bilateral narrow bony cochlear nerve canals remains elusive. More frequent coexistence of internal auditory canal narrowing among unilateral narrow bony cochlear nerve canal cases suggests that bilateral narrow bony cochlear nerve canals are not just a duplicate of the unilateral narrow bony cochlear nerve canal.
