Cephalometric and Anthropometric Changes and Their Relation to Patients' Satisfaction After Orthognathic Surgery.

OBJECTIVE: The aim of this prospective study was to evaluate the correlation between cephalometric and anthropometric facial changes and satisfaction level of class III patients after bimaxillary orthognathic surgery. METHODS AND MATERIALS: Totally, 29 class III patients (mean age = 24.23 +/- 4.2) undergoing one-piece Lefort 1 osteotomy and mandibular setback were included. Pre- and postoperative lateral cephalograms were taken. Thirteen cephalometric and 17 anthropometric facial measurements were evaluated. A 6-item questionnaire of Rustemeyer's study was used to assess patient's satisfaction after surgery. The Wilcoxon signed-rank test, paired sample t test and Spearman's correlation analysis were used as statistical analysis. RESULTS: Facial aesthetic and masticatory improvement was highly significant (P < 0.001), while opinion differences between patients and relatives/friends were not significant (P = 0.334). Increased upper lip length (P = 0.037) and decreased nasal tip protrusion-nose height index (P = 0.017) correlated positively with aesthetic improvements after surgery. CONCLUSION: Although the association between parameters and satisfaction questionnaire was found, other influential factors should be considered before surgery as well.
