Abstract
For effective tympanoplasty when bacterial infection is present, it is desirable to operate on a dry drum. We performed 25 tympanoplasties for chronic otitis media with infection of Pseudomonas aeruginosa over 8 years in our hospital from May 1993 to April 2001. These ears consisted of 14 ears with cholesteatoma,8 ears with chronic otitis media perforation and 3 ears with postoperative chronic otitis media. We used sensitive antibiotics and washed the tympanic cavity preoperatively. Although they took sensitive antibiotics during postoperation,2 patients suffered swollen posterior external ears. And the gauze on the reconstructed drum was cultured in 15 cases. Most chronic otitis media patients with Pseudomonas aeruginosa can make good progress, provided they take sensitive antibiotics. Often it was a mixed infection that caused complications. We should pay attention to infection by MRSA (Methicillin resistant Staphylococcus aureus), drug resistant CNS (Coagulase-negative staphylococcic) and Bacteroides. We should be careful to watch for symptoms of infection postoperatively in the gauze, on the posterior of the external ear and in the external canal.
