title: Complications associated with maxillary osteotomies.
abstract: There are certain complications involved in maxillary ostetomies; devitalization of teeth, loss of part or all of the osteotomized segment, and relapse are possible problems. The paramount cause of the complications in seven different cases seemed to be the interruption of the blood supply to the operative site. A seven-point guideline is formulated; it integrates preoperative planning, surgical procqedures, and postoperative care.
