ABSTRACT:
Introduction: Dentofacial deformities can have a negative impact on quality of life, self-image, social behaviour and public perception. A combination of orthodontics and orthognathic surgery can correct functional abnormalities and improve facial esthetics. In the past, prior surgery, various two-dimensional (2D) methods have been used to assess a three-dimensional face planification. Nowadays, obtaining a 3D facial image of the patient prior to surgery is essential for accurate evaluation of facial aesthetics.
Aim: Establish the accuracy of the 3D facial soft tissue prediction model compared to the 3D facial soft tissue result of patients who underwent orthognathic surgery.
Methods: Twenty-six patients who needed orthognathic surgery underwent Vectra H1 three-dimensional stereophotogrammetry face imaging. A 3D prediction model was made prior to surgery during the planification phase. In order to obtain each patient’s final soft tissue profile six months following surgery, the patients were asked to repeat the 3D stereophotogrammetry procedure. At last, the 3D final model of each patient was contrasted with his/her 3D prediction model.
Results: Specific reference points were measured in each 3D model by the same operator in order to avoid bias. The following reference points were measured: distance of subnasale-stomion, stomion-menton, lower nose width, facial thirds, upper and lower lip to nasomental line, nasofacial angle, nasolabial angle, nasomental angle, nasocervical angle, mentocervical angle. It was shown that the final 3D model and the 3D prediction model were remarkably comparable.
Discussion: We can draw the conclusion that the soft tissue profile prediction model is a useful tool before undergoing orthognathic surgery based on the study’s findings.
