Congenital cochleovestibular malformation

Definitions
A rare otorhinolaryngological malformation with characteristics of varying degrees of malformation of the inner ear associated with severe to profound congenital sensorineural hearing loss in the absence of cochlear nerve anomalies (hypoplasia or aplasia). Categorization of the malformation is based on the morphology of the cochlea, modiolus, and lamina cribrosa, which can range from normal development of these structures (with the malformation being limited to other structures of the inner ear) to their complete absence.
