Objective: The aim of the study was to present cases of otogenic intracranial complications that were diagnosed and treated in our clinic. Material and Methods: Nine cases who presented to the Kocaeli University Medical Faculty Ear-Nose-Throat clinic between 2004 and 2007 were reviewed. All patients were males and the age of the patients ranged from 18 to 75 years. Temporal bone CT, cranial MRI, neurootological examination, hematological and odiologic examinations were performed routinely in each case. MR venography was performed in six patients. Results: Seven cases who developed complications had chronic otitis media with cholesteatoma. Granulation tissue was detected during the operation in two patients. Four patients had dual complications and overall 13 complications developed. The complications included 5 lateral sinus thrombosis, 2 temporal lobe brain abscesses, 2 meningitidis, 2 perisinusoidal abscesses, 1 cerebellar abscess, and 1 otitic hydrocephalus. 5 patients with cholesteatoma underwent radical 1 A case with bilateral mastoidectomy and radical mastoidectomy was performed in the remaining two. mastoiditis, which caused menengitis underwent bilateral simple mastoidectomy. Modified radical mastoidectomy was performed in the patient with no cholesteatoma. We performed additional surgical procedures according to the type of complications. Medical treatment was administered to the patients pre- and postoperatively. Two patients had ataxia, facial paralysis and hearing loss. None of the patients died. Conclusion: Intracranial complications of chronic otitis media have high mortality and morbidity rates. Early diagnosis and treatment of these complications has great importance for society health.
