잠재성 유양 돌기염 환자에서 합병된 뇌농양 1례

With the advent of braod-spectrum antibiotics and inadequate usage, the frequency of serous otitis media and masked mastoiditis after acute otitis media is increased. The first awareness of the mastoiditis may be following the presentation of an intracranial complications such as meningitis, lateral sinus thrombosis or brain abscess. We experienced a diabetic patient with masked mastoiditis and brain abscess without tympanic me- mbrain perforation, who had recieved myringotomy and antibiotic treatment more than once a year due to repeated ear fullness since 20 years ago. We performed simple mastoidectomy, myringotomy with v-tube insertion and aspiration of brain abscess. The clinicians are urged to maintain a high suspicion of masked mastoiditis in the high risk patients, including newborn, diabetic, elderly, immunosuppressed or debilitated patients.
