Microbiology of chronic and recurrent otitis media with effusion in young infants.
Chronic otitis media with effusion (OME) has been assumed to be sterile, since several reports in the literature have described unsuccessful attempts to culture bacteria from it. However, several recent studies have confirmed an earlier report that there is a significant frequency of bacteria in the middle ears of children with chronic and/or recurrent OME. Similar studies in young infants with chronic and/or recurrent OME have not been previously reported. In this study, cultures were obtained at the time of myringotomy and tympanostomy tube insertion from 50 infants aged 1-12 months who had chronic and/or recurrent OME. From the 80 ears of 40 infants without cleft palate, 32% had bacteria isolated from their middle ears; 22% had Streptococcus pneumoniae or Haemophilus influenzae. In 21 of these ears, no effusion was apparent at myringotomy, but in 28% bacteria were isolated from middle ear washings. From the 20 ears of 10 infants with an unrepaired cleft palate, 55% had bacteria present in their middle ear aspirates; 50% had S. pneumoniae or H. influenzae. Even though the significance of bacteria in chronic OME in children, and now in young infants, is unclear at present, a therapeutic trial with an antimicrobial agent prior to surgical intervention would appear to be reasonable until such therapy is tested in a randomized, clinical trial.
