Resumo IntroductionDespite the advent of antibiotics and immunizations in the last century, complications of otitis media remain quite frequent, have high morbidity and mortality rates, and pose a challenge to the otorhinolaryngologist. ObjectiveTo establish the annual incidence of intratemporal complications of otitis media and prospectively evaluate patients via an analysis of epidemiologic and clinical aspects. MethodProspective, observational study. Between February 2010 and January 2011, patients admitted to a tertiary care, university-based otology practice with diagnosis of otitis media and an associated intratemporal complication (ITC) were included in the study. The following data were evaluated: age, sex, type of ITC, treatment, imaging tests findings, type and degree of hearing loss, and clinical outcome. The overall incidence of all complications and of each complication individually was determined. ResultA total of 1,816 patients were diagnosed with otitis media. For 592 (33%) individuals, the diagnosis was chronic otitis media; for 1,224 (67%), the diagnosis was acute otitis media. ITCs of otitis media were diagnosed in 15 patients; thus, the annual incidence of intratemporal complications was 0.8%. We identified 19 ITC diagnoses in 15 patients (3 patients had more than one diagnosis). Labyrinthine fistulae were diagnosed in 7 (36.8%) individuals, mastoiditis in 5 (26.3%), facial palsy in 4 (21.1%), and labyrinthitis in 3 (15.8%). ConclusionThe incidence of intratemporal complications in Brazil remains significant when compared with developed countries. Chronic otitis media with cholesteatoma is the most frequent etiology of intratemporal complications. Labyrinthine fistula is the most common intratemporal complication.
