title: Intracranial complications of chronic otitis media.
abstract: The objective of this study was to review our experience on intracranial complications (ICC) secondary to chronic otitis media (COM), and to investigate its clinical characteristics and treatment approaches. From January 1996 to December 2012, 17 patients with ICC secondary to COM were identified and included in this study, and were analyzed retrospectively. 13 out of these 17 cases (76.4 %) have cholesteatoma. The most common intracranial complication is brain abscesses (52.9 %), followed by meningitis (29.4 %), perisinus abscess (11.7 %), and epidural abscess (6 %). All patients underwent emergency mastoidectomy within the first 24 h after clear diagnosis. 7 patients underwent brain abscess drainage or abscess excision at the time of ear surgery. The mortality rates are 0 %. No recurrence was found in the 24-month follow-up period. Cholesteatoma was strongly associated with ICC. An early diagnosis and active surgical intervention in collaboration with proper antibiotic treatment is the key to cure.
