vestibulocochlear nerve damage

vestibulocochlear nerve damage

These nerves are twined together to form the vestibulocochlear nerve (eighth cranial nerve). Sensorineural hearing loss (SNHL) is a type of hearing loss in which the root cause lies in the inner ear or sensory organ (cochlea and associated structures) or the vestibulocochlear nerve (cranial nerve VIII).

Labyrinthitis refers to inflammation of the membranous labyrinth, resulting in damage to the vestibular and cochlear branches of the vestibulocochlear nerve. Cranial nerve damage can cause sensory, motor function and parasympathetic abnormalities, depending on which of the 12 cranial nerves are affected. Diabetes mellitus3. . .
