Abstract
Surgical reconstruction of maxilla is technically challenging and time consuming. The study reports a new method of maxillary reconstruction assisted by preoperative surgical simulation and accurate transferring templates. Six patients requiring maxillary reconstruction were enrolled in our study. Templates of maxillary resection, fibula cutting, and positioning were designed based on computed tomography (CT) data and fabricated via rapid prototyping technique. Resection, fibula cutting, and positioning were performed according to the templates. Accuracy was evaluated by measuring deviation, performed by superimposing preoperative planning and postoperative maxilla. The surgery was performed faithfully to the preoperative planning. The facial contour was satisfied. Postoperative CT scans showed high accuracy of the surgical implementation. The average central point deviation, maximum deviation, and rotation were 0.58 mm, 1.53 mm, and 6.0°, respectively. With preoperative surgical simulation and templates, maxillary reconstruction can be performed accurately.
