[Group F chronic cholesteatomatous otomastoiditis with spontaneous fistulization]

Chronic cholesteatomatous otomastoiditis is a rare entity in childhood, and its spontaneous intra- or extracranial fistulization is even more uncommon. The otologic sequelae are always important, especially when the disease is long standing. The agents causing chronic otomastoiditis are the same as those that can cause otitis. When there is associated cholesteatoma, Gram-negative and anaerobic bacilli are often present, but not group F beta-hemolytic streptococcus. The case of an 8-year-old boy with chronic cholesteatomatous otomastoiditis and spontaneous fistulization caused by group F beta-hemolytic streptococcus is reported.
