Tuberculous otitis media: clinical aspects of 12 cases.

The clinical features of tuberculous otitis media (TOM) have changed. This study was performed to evaluate changing trends in the clinical manifestations of TOM. We reviewed a series of 12 cases of TOM (13 ears) recently treated at Osaka Prefectural Habikino Hospital. The results showed a mean age of 41 years and a male predominance of 1.4 to 1. Central or total perforations of the tympanic membrane were observed in most cases, but none of the patients had multiple perforations. Nine patients (75%) had active pulmonary tuberculosis. Normal lung status or inactive pulmonary tuberculosis was significantly more frequent in the older age group. Diagnosis of primary TOM required more time than that of secondary TOM. Most cases of primary TOM had high infectiousness of the primary lesion. We summarize the clinical features of patients who should be evaluated for TOM.
