Question

Quizplus · Accepted Answer

Cochlear nerve degeneration is a cause of sensorineural deafness, not conduction deafness. Conduction deafness is caused by disruptions in the transmission of sound waves through the outer and/or middle ear, while sensorineural deafness is caused by damage to the inner ear or the cochlear nerve. Otosclerosis, middle ear infections, and impacted cerumen can all cause conduction deafness by interfering with the conduction of sound through the ear canal or middle ear.
