Residual bacterial infection in the tympanic cavity following surgery for ears with chronic discharge


, : Residual bacterial infection in the tympanic cavity following surgery for ears with chronic discharge. Auris Nasus Larynx 23(0): 13-19

In surgical treatment of ears with chronic discharge, pathogenic microorganisms may remain in the middle ear even after meticulous tympanomastoidectomy, and cause recurrent infection unless an appropriate antimicrobial agent is administered. The present study was conducted to determine the incidence of residual bacterial infection in the tympanic cavity by examining secretions from a drainage tube placed there via the mastoid cavity during surgery. Comparison of the bacterial flora before and after surgery demonstrated that some of the microorganisms continued to be present in the tympanic cavity for up to 2 weeks despite medication, and that the incidence of Pseudomonas aeruginosa and Staphylococcus epidermidis remained fairly high.
