Otitis media (OM) is considered a potentially severe disease due to the risk of complications. OBJECTIVE: To establish the annual incidence of intratemporal complications (ITC) resulting from OM and to prospectively assess patients for epidemiological and clinical factors. METHOD: This prospective cohort study included patients admitted during one year at a university hospital diagnosed with intratemporal complications of OM. Patients were analyzed for age, gender, type of intratemporal complication, treatment, and clinical outcome. The overall incidence of complications and the specific incidence rates of each type of complication were determined. RESULTS: 1,816 patients were diagnosed with OM; 592 (33%) had chronic OM; 1224 (67%) had acute OM. Fifteen patients were diagnosed with OM ITC, adding up to an annual incidence of 0.8%. Nineteen diagnoses of ITC were made in 15 patients. Seven (36.8%) patients were diagnosed with labyrinthine fistula, five (26.3%) with mastoiditis, four (21.1%) with peripheral facial palsy, and three (15.8%) with labyrinthitis. CONCLUSION: The incidence of intratemporal complications remains significant when compared to the rates seen in developed countries. Chronic cholesteatomatous otitis media is the most frequent etiology of intratemporal complications. Labyrinthine fistula is the most common intratemporal complication.
