Using virtual surgical planning for resection of jaw tumor and accurate reconstruction

Abstract

Objective To review the patients who underwent accurate maxillary and mandibular reconstruction with vascularized osteomyocutaneous flap using virtual surgery and evaluate the postoperative results. Methods From June of 2009 to December of 2014, ninety ⁃four patients were treated in our department. In virtual surgical planning, maxillectomy and mandibulectomy were simulated and donor site bone was superimposed mirror image of normal maxil⁃ la and mandible to complete accurate maxillary and mandibular reconstruction. Maxillectomy, mandibulectomy and bone reconstruction were performed using stereomodels and guided templates to replicate the virtual planning. Actual re⁃ construction result was compared with that of virtual surgery. The patients were asked to assess their satisfaction with fa⁃ cial appearance at 1 year postoperatively. Results Good bony unions and occlusion were observed in 94 patients. The actual results were basically in accordance with that of virtual surgery. The actual deviation between postoperative CT and preoperative virtual surgical planning was no more than 1 mm matched by computer software. All patients reported their facial appearance were excellent or good at 1 year postoperatively. Conclusion The ideal contour of neomaxilla and neomandible and good function with dental rehabilitation can be gained after accurate maxillary and mandibular re⁃ construction with vascularized osteomyocutaneous flap using virtual surgery
