Abstract

Patients with maxillary hypoplasia secondary to cleft lip and palate present numerous challenging problems for the oral and maxillofacial surgeon, These patients present with maxillary hypoplasia in multiclimensions, and often have thin or structually weak bone. This deformity has been traditionally corrected by Le Fort I osteotomy and acute skeletal advancement with wide surgical exposure. The long-term results of cleft patients with maxillary deficiency treated with this traditional approach has been sometimes disappointing, and an increased relapse tendency has been reported, Distraction osteogenesis for these cleft patients offers successful results while potentially minimizing the risk of relapse. Advancing the maxilla via distraction forces requires only a minor surgical procedure that maintains vascularity and neurosensory integrity. Moreover, the response of the facial soft tissues during maxillary distraction has proven to be more favorable than with a conventional LeFort I osteotomy. The purpose of this report is to present the use of maxillary distraction osteogenesis by rigid external distraction (RED) system for the treatment of patient with maxillary deficiency secondary to cleft lip and palate.

본 교실에서는 상악골의 열성장을 보이는 구순구개열환자에서 RED 장치를 이용한 골신장술을 통하여 상악골의 점진적인 전방이동을 실시하고 약 3년정도의 추시기간을 포함하는 현재까지 특별한 기능 장애없이 양호한상, 하악관계 및 안모를 보이는 증례를 문헌고찰과 함께 보고하는 바이다.
