Patients with a cleft lip and palate typically show a high incidence of Class III malocclusion and mid-facial retrusion. Maxillary anterior segmental distraction osteogenesis (MASDO) facilitates the forward advancement of the anterior maxillary segments without affecting the patient’s velopharyngeal function. The segmental osteotomy also corrects the anteriorly-flattened dental arches and enhance the crown exposure of the upper incisors. Furthermore, MASDO can be applied in combination with transverse distraction osteogenesis or LeFort1 osteotomy. I will demonstrate that MASDO is effective for correcting severe skeletal Class III problems in patients with cleft lip and palate.
