Sensorineural impairment in unilateral otosclerosis.
Audiometric findings were evaluated in a group of patients with clinical unilateral otosclerosis. A comparison was made between bone conduction threshold in the better hearing ear and the ear with the mixed hearing loss. Over 50% of the patients had a significant elevation in the bone conduction thresholds in the ear with clinical otosclerosis as compared to the uninvolved ear. A pair of temporal bones from a patient with unilateral otosclerosis and unilateral mixed hearing loss is presented.
