Nasal Soft Tissue Change Following Bimaxillary Orthognathic Surgery

Objective: The purpose of this study is to identify the correlation between maxillary movement and nasal soft tissue changes on three-dimensional reconstructed cone beam computed tomography (CBCT) images after Le Fort I osteotomy. Materials and Methods: The authors also investigate the long-term change of alar base width (ABW) to determine the effect of cinch suture. The authors retrospectively studied 52 subjects (14 males and 38 females) who were treated by bimaxillary orthognathic surgery including Le Fort I osteotomy and mandibular ramus surgery. The landmarks and planes were established on three-dimensional reconstructed CBCT images. The authors measured each parameters preoperatively, 1 month postoperatively, and 1 year postoperatively. Results: There was no significant correlation between the horizontal movement of A-point and the widening of ABW (P
