A study of 177 children aged 6 months to 7 years suggested that recurrent episodes of AOM increase the risk of spontaneous tympanic membrane perforation (STMP). In addition, the study, by Marchisio et al, found a high frequency (50.8%) of nontypeable H influenzae in the middle ear fluid of patients with AOM with STMP, particularly in those with recurrent STMP. M catarrhalis and S pneumoniae (35.0% and 27.1% of cases, respectively) were the next most common bacterial pathogens found in AOM with STMP. [19]
