This study evaluated postoperative soft tissue changes in skeletal Class III patients following minimally invasive and conventional orthognathic surgery using three-dimensional stereophotogrammetric analysis.
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.

Bimaxillary orthognathic surgery performed using a minimally invasive surgical approach characterized by limited soft tissue dissection, reduced surgical exposure, and preservation of vascular integrity to minimize postoperative soft tissue alterations.
Bimaxillary orthognathic surgery performed using conventional surgical exposure and standard soft tissue dissection techniques.
