Objective: To identify nasal soft tissue changes occur after Le Fort I osteotomy and prospectively compare the efficacy of three surgical techniques for controlling nasal width after Le Fort I osteotomy.Methods: 45patients (14males and 3 lfemales, with mean age of 22.6±2.8years), who had received Le Fort I osteotomy at Peking University Hospital of Stomatology from 2011 to2013 were included.They were randomly divided into three groups.The control group received traditional intraoral alar base cinch suture (ABCS); the experimental groupl received extraoral ABCS, and the experimental group2 received additional intraoral suture of the soft tissue of G.lat on the basic of traditional method.All patients had taken 3D-photos using 3dMD camera before operation, and 3, 6 months after operation.The pre-and postoperative nasal measurements, whose main indicators were distances of Sbal-Sbal,G.lat-G.lat and A1-A1 in 3D photos, were recorded by a single examiner three times with a time-interval of one week.The difference between three groups was statistically analyzed by using SPSS 13.0.
