Biofilm Surface Area in the Pediatric Nasopharynx

Abstract

Adenoids removed from patients with CRS had almost their entire mucosal surface covered with biofilms vs scant coverage for patients with OSA. Biofilms in the nasopharynx of children with CRS may act as a chronic reservoir for bacterial pathogens resistant to standard antibiotics. The mechanical debridement of the nasopharyngeal biofilms may explain the observed clinical benefit associated with adenoidectomy in this subset of pediatric patients.
