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

To review the patients who underwent accurate maxillary and mandibular reconstruction with vascularized osteomyocutaneous flap using virtual surgery and evaluate the postoperative results.

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 maxilla 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 reconstruction result was compared with that of virtual surgery. The patients were asked to assess their satisfaction with facial appearance at 1 year postoperatively.

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.

The ideal contour of neomaxilla and neomandible and good function with dental rehabilitation can be gained after accurate maxillary and mandibular reconstruction with vascularized osteomyocutaneous flap using virtual surgery.
