Introduction: Cleft lip and palate is the most common congenital deformity of the head and neck and about 25%- 60% of cleft lip and palate patients develop maxil lary hypoplasia and midface retrusion. Early treatment of maxillary hypoplasia has been commonly used orthodontic treatment and orthognathic surgery. Recently, maxillary distraction osteogenesis became one of the standard treatment procedures for correction of severe maxillary hypoplasia and midface retrusion. In this study, we used intraoral distraction osteogenesis for correction of maxillary hypoplasia and midface retrusion in cleft lip and palate patients. Aim of the study: The aim of this study was to evaluate clinically and radiographically the use of midface distraction osteogenesis for treatment the midface retrusion and maxillary hypoplasia in cleft lip and palate patients. Patients and Methods: This study was carried out on eight adult cleft lip and palate patients had class III malocclusion, negative overjet, and a concave facial contour due to maxillary hypoplasia. All patients will be assessed clinically and radiographically using panoramic x-ray, cephalometry, and CT-scans. The surgical procedure included maxillary osteotomy at a level of classic LeFort I osteotomy and using the intraoral maxillary distracters through intraoral approach. Results: the long-term clinical and cephalometric results demonstrated that the intraoral midface distraction osteogenesis procedure was successful for achieving a balanced facial appearance and normal functional occlusion with fewer tendencies to relapse after 1year follow-up without serious complications. Conclusion: The intraoral midface distraction osteogenesis is a highly effective treatment modality for maxillary advancement in cleft lip and palate patients
