Intraoral quadrangular Le Fort II osteotomy

Abstract The technical aspects of the intraoral quadrangular Le Fort II osteotomy are described, and the anesthetic technique, blood loss, operating time, intraoperative and postoperative complications, length of hospitalization, and length of fixation in seven cases are reported. This procedure was predictable and reproducible with few complications, had low surgical and postsurgical morbidity, exhibited excellent initial skeletal stability, provided esthetics superior to those achieved with lower osteotomy and onlay bone grafting techniques, and demonstrated versatility within limits.
