Anterior maxillary distraction osteogenesis for cleft lip and palate patients - A case series

Abstract

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.

Orthodontic Pre Grafting Closure of Large Alveolar Bony and Soft Tissue Gaps: A Novel Nonsurgical Protraction of the Lesser Segments in Growing Patients With Cleft Lip and Palate

“…The effectiveness of distraction osteogenesis (DO) in the dentoalveolar region is well-documented (Liou et al, 2000; Pai et al, 2018). Many studies have demonstrated the reduction in the size of a wide alveolar cleft through segmental DO, which allows, not only the lengthening of bone but also soft tissue expansion.…”
