Summary of Sensorineural hearing loss
Sensorineural hearing loss is a type of hearing loss or deafness in which the root cause lies in the inner ear (cochlea and associated structures), vestibulocochlear nerve (cranial nerve VIII), or central auditory processing centers of the brain. Sensorineural hearing loss accounts for about 90% of reported hearing loss. A hallmark of sensorineural hearing loss is that it is asymmetrically distributed, usually toward the high frequency region, or may have a notch at some frequency. It is generally permanent and can be mild, moderate, severe, profound, or total.
