Anterior Maxillary Segmental Distraction Osteogenesis for Treatment of Maxillary Hypoplasia in Patients With Repaired Cleft Palate

Objective: This study is to present experiences of using anterior maxillary segmental distraction osteogenesis (AMSDO) with internal distractors for treatment of maxillary hypoplasia in patients with repaired cleft palate. Materials and Methods: A total of 42 patients of maxillary hypoplasia with repaired cleft palate were included in this study, and underwent AMSDO. Cephalometric analysis and speech quality assessments were performed to evaluate the changes after AMSDO and its long-term effect on stability. Results: All cases had successfully accomplished AMSDO. The average SNA (°), NA-FH (°), ANS-PNS (millimeter), and Overjet (millimeter) have change to 80.41°, 89.51°, 55.64 mm, and 2.52 mm, respectively (P
