计算机导航是颅颌面外科日常手术中常用的工具，特别是对于脸中区域，但在下颌骨的应用经验仍然有限。材料与方法本文报道3例下颌骨导航术：2例智齿碎片切除，1例成釉细胞瘤切除。结果该方法简便、省时。这3例患者的手术技术都很容易操作。随后没有出现典型的并发症，比如舌神经损伤或口底血肿，这些都是外科医生在仔细寻找牙齿碎片时可能出现的。结论下颌骨计算机导航是一种很有前途的工具，尤其适用于清除异物、牙碎片、边缘清晰的囊性病变或肿瘤。优点是病变的三维表现，神经位置的评估，以及术前可能的移植物大小评估。进一步的应用可能是正颌手术，包括牵张计划、骨肿瘤手术、囊肿切除和骨重建计划。
Computer navigation is a common tool in the daily routine of craniomaxillofacial surgery, particularly for the mid-face region, but experience in mandible application is still limited. Materials and methods Three cases are presented with navigation of the mandible: two cases of removal of a wisdom tooth fragment and one case of resection of an ameloblastoma. Results The described method is simple and time-saving. In all three patients the surgical technique was easy to perform. No typical complications followed, like damage of the lingual nerve or a hematoma of the mouth floor, which can appear when the surgeon intensely looks for a tooth fragment. Conclusions Computer navigation of the mandible is a promising tool, in particular for removal of foreign bodies, tooth fragments, and cystic or tumor lesion with clear margins. Advantages are 3D presentation of the lesion, evaluation of nerve location, and possible preoperative evaluation of graft size. Further applications could be orthognathic surgery, including distraction planning, bony tumor surgery, cyst removal, and planning for bony reconstructions.
