UNASSIGNED: We developed a reconstruction approach by combining the 3dMDface System (3dMD) with the cone beam computed tomography (CBCT). Firstly, with the extra-oral incision line, we evaluated the shape and the size of the extra-oral defect with 3dMD digitally. Then we used the corresponding maxillary and mandible tooth positions to record the intra-oral defect, which was then converted to digital images by combining 3dMD and CBCT. The islands of the anterolateral thigh perforator flap were then designed after the locations of the perforators were detected with Doppler ultrasonography.
UNASSIGNED: A clinical case diagnosed as dermatofibrosarcoma protuberans was presented to illustrate the approach. The patient\'s tumor resection and the size of multiple defects were measured and simulated via the virtual surgery system. A three-island perforator flap from the descending branch of the lateral femoral circumflex artery was designed accurately. Two weeks postoperatively, the flap was healed as anticipated and the patient was satisfied with the profile.
UNASSIGNED: The combination of the 3dMD and CBCT technologies improves the accuracy and fitness of extra- and intra-oral soft tissue reconstruction.
■我们通过将3dMDface系统(3dMD)与锥形束计算机断层扫描(CBCT)相结合,开发了一种重建方法。首先,随着口外切口线,我们用3dMD数字评估了口外缺损的形状和大小.然后我们使用相应的上颌和下颌牙齿位置来记录口腔内缺损,然后通过结合3dMD和CBCT将其转换为数字图像。然后,在用多普勒超声检查发现穿支的位置后,设计股前外侧穿支皮瓣的岛。
■提供了一个诊断为隆突性皮肤纤维肉瘤的临床病例来说明该方法。通过虚拟手术系统测量和模拟患者的肿瘤切除情况和多个缺损的大小。准确设计了旋股外侧动脉降支的三岛穿支皮瓣。术后两周,皮瓣如预期的那样愈合,患者对其外形感到满意.
■3dMD和CBCT技术的结合提高了口腔内外软组织重建的准确性和适应性。
