Abstract: OBJECTIVE: To clarify true incidence of sensorineural hearing loss in ears with chronic otitis media (COM). METHODS: Bone conduction (BC) hearing thresholds of 180 preoperative patients (207 ears) with COM and 226 normal individuals (289 ears) were measured by audiometry, and the percentage of ears with BC thresholds being higher than normal range was evaluated in the COM group. In the COM group, the size of the perforation on the eardrum (n=196) and the cross-sectional area of the mastoid air cells based on the axial CT image (n=103) were also measured and correlated with the results of BC threshold. RESULTS: The percentage of ears with BC thresholds being higher than normal range calculated from comparison to the control group tended to increase with age, ranging from 4.5% in the 20s to 34.1% in the 60s with an average of 26.6%. The increase in the BC thresholds did not correlate with the size of eardrum perforation, but correlated well with the size of the mastoid air cells. CONCLUSION: These results may suggest that all measures for early cure, including surgery, should be considered as early as possible for patients with COM.
