In recent years, intraoperative surgical guides have been widely used in oral and maxillofacial surgery to navigate the resection sites. However, most of them are designed for segmental mandibulectomy and determine only the anterior-posterior cutting sites. In the case of marginal mandibulectomy, the depth and angle of the resection need to be considered in addition to the anterior-posterior cutting site. This report describes a method for creating a translucent mandible model with a colored tumor that enables visualization of the tumor depth and a surgical guide for marginal mandibulectomy with a planned resection angle. If accurate surgical planning and intraoperative navigation are established using this method, personalized surgery is realized according to tumor features and hence avoids over- or under-resection.
近年来，术中手术导板已广泛应用于口腔颌面外科手术中，用于确定切除部位。然而，大多数手术导板是为节段性下颌骨切除术设计的，只能确定前后切割部位。在边缘性下颌骨切除术中，除了前后切割部位外，还需要考虑切除的深度和角度。本报告介绍了一种创建带有彩色肿瘤的半透明下颌骨模型的方法，该方法能够显示肿瘤深度，并介绍了一种具有计划切除角度的边缘性下颌骨切除术手术导板。如果使用该方法建立准确的手术规划和术中导航，则可根据肿瘤特征实现个性化手术，从而避免切除过多或过少。
