Computed tomography of the temporal bone in tuberculous otitis media

  • Tomoyuki Hoshino (a1), Hiroshi Miyashita (a1) and Yoshihiro Asai (a1)


Nine cases of tuberculous otitis media were treated by us over the past 10 years. Six patients presenting with large tympanic membrane perforations were treated for suppurative otitis media at various ENT clinics. The remaining three patients presented without perforation. Intractable otorrhoea, aggravation of hearing loss, dizziness, and in one case facial palsy, resulted in eventual referral to us. Histological examination revealed a tuberculous granulation, confirming the diagnosis in most cases. CT in four cases with profound sensorineural hearing loss showed bone destruction of the otic capsule around the oval window and the promontory. Changes noted included a notch in one case, disappearance of the bony contour around the hook in two cases, and a distinct fistula in the final case. A cochlear fistula seemed to be characteristic of advanced tuberculous otitis media.
