简要总结
This study evaluated postoperative soft tissue changes in skeletal Class III patients following minimally invasive and conventional orthognathic surgery using three-dimensional stereophotogrammetric analysis.
详细描述
This study was conducted on 31 adult patients who underwent bimaxillary orthognathic surgery. Patients were divided into minimally invasive (n=15; mean age: 23.2 years) and conventional surgery groups (n=16; mean age: 22.4 years) according to the surgical technique performed. High-resolution three-dimensional stereophotogrammetric facial images were obtained preoperatively (T0) and at least six months postoperatively (T1). Three-dimensional displacements of soft tissue anthropometric landmarks, as well as linear and angular measurements, were analyzed. Data distribution was assessed using the Shapiro-Wilk test, and appropriate parametric and non-parametric tests were used for intra- and intergroup comparisons. Statistical significance was set at p<0.05.

研究组 & 干预措施
Minimally Invasive Orthognathic Surgery
Skeletal Class III patients treated with minimally invasive bimaxillary orthognathic surgery characterized by reduced soft tissue dissection, limited surgical exposure, and preservation of vascular integrity compared with the conventional approach. This technique aims to minimize postoperative soft tissue alterations and improve postoperative recovery. Soft tissue changes were evaluated using three-dimensional stereophotogrammetric analysis.

Conventional Orthognathic Surgery
Skeletal Class III patients treated with conventional bimaxillary orthognathic surgery. Postoperative soft tissue changes were evaluated using three-dimensional stereophotogrammetric analysis.
