Simulation-guided navigation: a new approach to improve intraoperative three-dimensional reproducibility during orthognathic surgery.
J Craniofac Surg. 2010 Nov; 21(6):1698-705.JC

Abstract

Because of the recent development of three-dimensional technology, computer software is increasingly being used for diagnosis, analysis, data documentation, and surgical planning for orthognathic surgery. Currently, the typical method to reposition jaws in the correct and planned location is based on the use of surgical splints, which have a quite high level of imprecision. The most important differences between planned and achieved maxillary movements are in the vertical and rotational positioning. Several methods have been described for intraoperative maxillary control, but none of these procedures is satisfactory. We present a new method to transfer individualized three-dimensional virtual planning of the patient using a navigation system in the operating room to improve reproducibility of the simulation. We enrolled 10 patients with dentofacial deformities from November 2008 to May 2009. All patients were studied and treated according to the following steps: cone-beam computed tomography data acquisition, virtual simulation of the surgical procedure, surgery with intraoperative navigation, and validation through reproducibility evaluation. We found 86.5% mean preoperative surgical plan reproducibility with the assistance of simulation-guided navigation compared with 80% mean reproducibility obtained in our previous group, in which no intraoperative navigation was performed. According to these results, we can assume that simulation-guided navigation would be a helpful procedure during orthognathic surgery to improve reproducibility of the preoperative virtual surgical planning.
