Antonini F, et al. - Via analyzing patients who had undergone bimaxillary orthognathic surgery, researchers analyzed the influence of time, and experience, on the accuracy of maxillary repositioning in bimaxillary orthognathic surgery performed utilizing virtual surgical planning (VSP). They compared the maxillary position on pre and postoperative computed tomography scans. Study participants were divided into groups according to the year in which VSP was performed and surgery completed. Overall, the results showed improved maxillary position accuracy over the years, with more accurate results in 2015, 2016, and 2017 surgical patients. In the horizontal direction, mean linear differences between planned and obtained results showed more accurate results, accompanied by transverse and vertical directions. For 51.3% of the measurements included in the sample group, an overall average discrepancy within 1 mm was found. In bimaxillary orthognathic surgery, time and surgeon experience can affect the precision of maxillary positioning.
