Abstract
In cleft lip and palate (CLP) patients, there are various degree of residual maxillofacial deformities in adolescent period. Usually, orthoganthic surgery for the cleft patients needs Le Fort I osteotomy and/or mandibular set-back surgery. Previous report from other institute had been shown that there is significant relapse after maxillary movement after Le Fort I osteotomy when the surgical advancement of the maxilla was over than 5 or 7mm in average. Recent comphrehensive report showed that most of the relapse was happened within 1 year and the total horizontal relapse of the maxilla was as high as 30% in average. Therefore, overcorrection is needed in maxillary surgery for cleft patients. Another concerns for cleft orthognathic surgery is the anatomical variation in pterygomaxillary region in cleft patients compared to control patients. Patients with CLP had larger and thicker pterygomaxillary dimensions, and the results imply that careful attention to pterygomaxillary anatomy is needed in patients with CLP undergoing Le Fort I surgery. This article reviews the pre and postoperative considering factors for orthognathic surgery for CLP patients.
