In this study we tried to define tumor resection, fibula cutting, and positioning by surgical templates to perform the mandible reconstruction surgery according to the preoperative simulation. The accuracy was evaluated through cadaveric surgery.
Five cadaveric mandibles and fibulas were obtained. Preoperative surgical simulation was performed. Surgical templates that defined tumor resection, fibula cutting, and positioning were designed and fabricated. Translation, angular deviation, and rotation of bone grafts, as well as translation of condyles, were measured.
The reconstructed mandibles showed high similarity to the surgical planning. The mean translation, angular deviation, and rotation of fibula segments of the reconstructed mandibles were 1.35 ± 0.86 mm, 3.36° ± 1.86°, and 8.13° ± 5.35°, respectively. In the mandible remnants, the translation of condyles was measured, with a mean of 1.39 ± 0.66 mm.
Our method of defining the tumor resection, fibula cutting, and positioning by surgical templates was accurate enough for mandible reconstruction surgery.
在本研究中，我们试图通过手术模板来定义肿瘤切除、腓骨截骨及定位，以便根据术前模拟进行下颌骨重建手术。通过尸体手术评估其准确性。
获取五具尸体的下颌骨和腓骨。进行术前手术模拟。设计并制作定义肿瘤切除、腓骨截骨及定位的手术模板。测量骨移植的平移、角度偏差和旋转，以及髁突的平移。
重建的下颌骨与手术规划高度相似。重建下颌骨腓骨段的平均平移、角度偏差和旋转分别为1.35±0.86毫米、3.36°±1.86°和8.13°±5.35°。在下颌骨残余部分，测量髁突的平移，平均值为1.39±0.66毫米。
我们通过手术模板定义肿瘤切除、腓骨截骨及定位的方法对于下颌骨重建手术足够精确。
