Abstract

|
Cleft lip and palate patients show midface hypoplasia, maxillary hypoplasia due to scar of previous surgery, and manifest as a class III malocclusion, retruded midface and shallow palate. These deformities have been treated with traditional orthognathic surgery. Although conventional Le Fort I osteotomy was performed on most cleft patinets with midface hypoplasia, it showed limited amount of maxillary advancement and high relapse tendency. Recently, when great amount of advancement are required in severe maxillary hypoplasia, distraction osteogenesis using RED system is widely used. But, several months of consolidation period is needed after distraction osteogenesis, occlusal relationship is not stable until mandibular setback surgery has done in mandibular hyperplasia cases and during these period, patients may feel discomfort. We present clinical cases of immediate rigid internal fixation after completion of maxillary distraction using RED system and simultaneous mandibular setback procedure in adult cleft and lip patients who show both maxillary hypoplasia and mandibular prognathism.
