Incidence of maxillary sinusitis following Le Fort I maxillary osteotomy

Twenty adult patients with maxillofacial discrepancies most amenable to correction by Le Fort I osteotomy were evaluated for the incidence of postoperative maxillary sinusitis. Before surgery, each patient was evaluated both radiographically, by Waters' projection technique, and subjectively, according to a brief questionnaire pertaining to sinus symptoms. Identical evaluations were carried out at three- and six-month intervals following surgery. The results show no increase in the incidence of maxillary sinusitis following Le Fort I osteotomy.
