Maxillary anterior segmental distraction osteogenesis (DO) has been the alternative treatment option for patients with midfacial retrusion. The patient showed unilateral cleft lip and palate, and premaxillary distraction with rigid external device (RED) was planned to solve midface deficiency and to create alveolar space. Significant advancement of A point was observed, but relapse of A point was detected during consolidation period. The vertical position of the ANS was found to have moved downward. Axis of upper incisor decreased after DO. Maxillary anterior segmental DO is effective for treatment of patient with cleft lip and palate. The alveolar space is regained successfully, and the facial profile is improved without velopharyngeal problems.
