Extracranial and intracranial complications of suppurative otitis media. Report of 102 cases.
During the eight-year period, 1983-1990, 102 cases of intracranial (IC) and extracranial (EC) complications from 17 144 suppurative otitis media were reviewed. The prevalence of each complication was 0.24 and 0.45 per cent respectively. Facial paralysis, subperiosteal abscess and labyrinthitis were the common complications among the EC group, while meningitis and brain abscess were common in the IC group. Twenty five per cent of the EC group and 44 per cent of the IC group had more than two complications. The reliable warning signs and symptoms for IC complications were fever, headache, earache, vestibular symptoms, meningeal signs and impairment of consciousness. Proteus spp., Pseudomonas aeuruginosa and Staphylococcus spp. were the commonest organisms isolated from both groups. Cholesteatoma and granulation/polyp in the middle ear/mastoid were the major findings in both patient groups. Mortality rate in the IC group was 18.6 per cent. Morbidity rate in each group was 14.3 per cent (EC) and 27.9 per cent (IC) respectively. Epidemiological presentations, clinical features and the result of treatment are discussed.
