Virtual surgical planning enables precise surgical planning and translation of this planning into the operating room. Preoperative maxillofacial computed tomography scans are compared to a reference skull to identify desired surgical changes. In facial feminization surgery, these include forehead recontouring/frontal table setback, gonial angle reduction, and possible chin repositioning/reshaping, while in facial masculinization surgery, this includes forehead augmentation and gonial angle/chin augmentation. Cutting and recontouring guides as well as custom implants are then custom manufactured. Common guides include osteotomy guides, depth drilling guides, ostectomy guides, and guides for one/two-piece genioplasty or chin burring. Common implants include mandibular and chin implants.
虚拟手术规划可实现精确的手术规划，并将规划准确转化到手术室中。术前颌面计算机断层扫描与参考颅骨进行比较，以确定所需的手术改变。在面部女性化手术中，这些改变包括额部重塑/额部前板后退、下颌角缩小，以及可能的颏部重新定位/塑形，而在面部男性化手术中，这些改变包括额部填充和下颌角/颏部填充。然后定制制造切割和重新塑形引导器以及定制植入物。常见的引导器包括截骨术引导器、深度钻孔引导器、凿骨术引导器，以及用于单/双块下颌骨整形术或颏部打磨的引导器。常见的植入物包括下颌骨和颏骨植入物。
