A cephalometric study on the changes of soft tissue profile (upper lip and nose) following two-jaw surgery

ABSTRACT

dentofacial deformity patient, Lefort I osteotomy and BSSRO are popular methods to correct the deformity. The purpose of this orthognathic surgery is to achieve esthetic facial appearance and proper function. Various articles have been reported on soft tissue change after orthognathic surgery in terms of esthetics. Especially a change of soft tissue in upper lip and nose is important to gain facial esthetic profile. To obtain accurate prediction of postsurgical esthetics, a proper understanding of relationship between maxillary surgical movement and soft tissue change. In other words, it is very helpful in treatment planning and prognosis of orthognathic surgery to predict soft tissue changes related to hard tissue change. A retrospective study of selected patients was undertaken to estimate and analyze the changes of soft tissue in upper lip and nose following surgical correction with Lefort I osteotomy and BSSRO. Preoperative, postoperative, and retention period data derived from lateral cephalometric analysis.
