Deafness
Classification:
• conductive (occurs in external or middle ear disorders; may have normal inner ear, but defect is in the mechanisms by which sound is transmitted; eg otitis media; can hear if sound is amplified)
• sensorineural (due to conditions of inner ear, cochlea, eighth cranial nerve; associated with trauma, infection, degenerative disease, congenital abnormality)
• combined conductive and sensorineural
• central (brain hearing centre is not functioning properly; sound reaches centre, but interpretation is impaired; eg may occur in trauma or neoplasm)
