abstract
- Single doses of different ototopical antibiotic preparations (OAPs) have been shown to have an unequal reduction of post tympanostomy tube otorrhea (PTTO). Microbial biofilm formation on the tympanostomy tube (TT) has been implicated as one cause of PTTO. The goal of this study was to determine if TT exposure to a single dose of OAP reduces biofilm formation by Pseudomonas aeruginosa.
