Abstract
Orthognathic surgery is considered a “clean-contaminated” procedure since the incisions are made in a field that contains oral bacteria. Therefore, postoperative antibiotic therapy is commonly recommended to minimize the risk of wound infection. Le fort I osteotomy procedures expose the wound to additional bacteria when surgical cuts are made through the maxillary sinus. Accordingly, some surgeons prefer to prescribe extended courses of postoperative antibiotics when a Le fort I osteotomy is part of the surgery. However, there is very little data regarding the surgical outcomes of prolonged antibiotic courses. We chose to evaluate whether the duration of postoperative prophylactic antibiotics (1 week vs 3 weeks) prescribed to post-Le fort I osteotomy patients has any correlation with the rate of postoperative infections or complications.
