Postoperative infection in the oral and maxillofacial region, at the First Department of Oral and Maxillofacial Surgery, Kyushu University, was studied (clinically). Of 1, 116 patients who underwent surgery from January 1995 to October 1999, 41 patients suffered from postoperative infection (3.7%). The rates of postoperative infection for oral malignant tumor, jaw deformity, benign tumor or cyst, injury, and cleft lip or palate were 12.7%, 1.9%, 1.5%, 1.2%, and 0.4%, respectively. The average operation time of the cases with postoperative infections was 9 hours 17 minutes, and it was longer than that of non-infection cases (p<0.001). Infections were recognized at 8.1 days after surgery, and it took 21 days until cessation, on average. Once a postop-erative infection occurred, agents of prophylactic administration of antibiotics were changed to therapeutic agents and were used for about 21 days. In 29 cases out of 41 postoperative infections, bacteriological examinations were performed, and a total of 66 microorganisms, including 9 MRSAs, were isolated. Concerning oral malignant tumor, 28 out of 34 postoperative infection cases were en bloc surgery cases.<BR>It is considered that avoiding wound dehiscence and the formation of dead space is important to reduce postoperative infections.
