[Perioperative antimicrobial prophylaxis in Obwegeser-Dal Pont surgery for prognathism].

Abstract

The value of ultra short antimicrobial prophylaxis using azlocillin in preventing postoperative wound infections was studied in a prospective clinical/bacteriological study in 41 orthognathic operations. Preoperatively the oral mucosa and pharyngeal flora of each patient was subjected to bacteriological identification with particular emphasis on anaerobes and sensitivity tests for organisms with established pathogenic potential. The results of a bacteriological examination of the redon drains on day 1 postoperatively indicated a contamination of the surgical wound. Clinically 31 patients showed moderate postoperative edema of the buccal soft tissues and 10 patients had hematomas or hemorrhages. In all patients the operation was followed by primary intraoral wound healing without any signs of an early infection.
