Distraction osteogenesis (DO) has become a mainstream surgical technique for patients with jaw deformities. This case report describes the surgical orthodontic treatment of maxillary hypoplasia in two patients of 14-19 years with cleft lip and palate. They were treated with anterior maxillary DO using rigid intraoral distractor device. Distraction was started after the initial latency period with activation of 0.8 mm/day until positive overjet was gained. Cephalometric analysis was performed twice for evaluation: Before surgery (Pre-Rx) and after distraction (Post-Rx). Both the distractions completed smoothly and maxilla was distracted efficiently. Maxillary prominence increased in both the patients with a positive overjet after distraction. DO provided an effective way to correct maxillary hypoplasia secondary to cleft lip and palate.
