title: Preoperative antibiotic prophylaxis in orthognathic surgery: a randomized, double-blind, and placebo-controlled clinical study.
abstract: OBJECTIVE
  This study evaluated the need for antibiotic prophylaxis in orthognathic surgery.
  
  
  METHODS
  Fifty-four patients (age range, 18 to 40 years) underwent bimaxillary orthognatic surgery. After randomization, a placebo (n = 19), 2,200 mg amoxicillin-clavulanic acid (n = 18), or 1,500 mg cefuroxime (n = 17) was administered in a double-blind fashion. During the first month, the postoperative course was observed according to the clinical parameters of infection, total leukocyte count and erythrocyte sedimentation rate (ESR).
  
  
  RESULTS
  Fifteen of 54 patients developed a wound infection. Of these, 10 had received a placebo; 3, cefuroxime; and 2, amoxicillin-clavulanic acid.
  
  
  CONCLUSIONS
  There was a statistically significant (P<.004) increased risk of having an infectious complication after bimaxillary orthognathic surgery without antibiotic prophylaxis. No significant difference in the incidence of infectious complications was found between the 2 medications.
