Bacteriology of the Postoperative Mucocele of the Maxillary Sinus / 대한이비인후과학회지

ABSTRACT

BACKGROUND AND OBJECTIVES: This study attempted to evaluated the bacteriology of the postoperative mucocele of the maxillary sinus. MATERIALS AND METHOD: We performed a retrospective review of intraoperative bacteriology culture results and clinical records of patients with the postoperative mucocele of the maxillary sinus between July 1997 and October 2002. The number of patients was 33 (25 male and 8 female). RESULTS: Cultures were found positive in 20 of 33 patients (61%)(One culture had two organisms). There was no growth in the cultures of 13 patients (39%). The most common organism observed was Coagulase-negative Staphylococcus (10 isolates). The mean duration between the previous Caldwell-Luc operation and the second operation was 18.9 years (4-40 years). CONCLUSION: These findings illustrate the bacteriology of the postoperative mucocele of the maxillary sinus and suggest that bacterial infection may play a certain role in the pathogenesis of the postoperative mucocele of the maxillary sinus.
