title: The stability of Le Fort I maxillary osteotomies in patients with simultaneous alveolar cleft bone grafts.
abstract: A retrospective study was performed on 20 patients who had been treated with Le Fort I maxillary osteotomies and simultaneous alveolar cleft bone grafts. The age range was 11 to 23 years, and there were 11 males and nine females. Changes in both anterior-posterior (A-P) and vertical direction were investigated using preoperative, immediate postoperative, and long-term postoperative lateral cephalometric radiographs. The results indicated little change between the immediate postoperative and long-term postoperative position of the maxilla in an A-P dimension, but in a vertical direction there was a great tendency for relapse.
