Nasopalatine cysts are common nonodontogenic cysts that occur in the maxilla. During the nucleation of large cysts extending to the floor of the nasal cavity, care must be taken to avoid damage to the nasal mucosa. In the present report, an innovative custom-made surgical guide made by a Three-dimensional printer is introduced for accurate enucleation surgery. The patient's cone-beam computerized tomography and dental model scan data were obtained, and a tooth-supported type of surgical guide was designed containing a circular plate structure showing the size of the cystic region, an indicator that showed the position of the bottom of the cyst, and a sliding stopper that was used to accurately indicate the position of the deepest cyst wall. The surgical tool enabled us to indicate the accurate size, location of the cysts, and approach direction. Although effective and accurate navigation systems have become increasingly available, the cost-effective and accurate computer-aided design/computer-aided manufacturing surgical guide system introduced in the present report could support the safe enucleation of large nasopalatine duct cysts.
鼻腭囊肿是发生在上颌骨的常见非牙源性囊肿。在大型囊肿向鼻腔底部扩展的成核过程中，必须小心避免损伤鼻黏膜。在本报告中，介绍了一种由三维打印机制作的创新定制手术导板，用于精确摘除手术。获取了患者的锥形束计算机断层扫描和牙模扫描数据，并设计了一种牙支持型手术导板，其包含一个显示囊性区域大小的圆形板结构、一个显示囊肿底部位置的指示器以及一个用于精确指示囊肿最深壁位置的滑动止动器。该手术工具使我们能够指示囊肿的准确大小、位置和入路方向。尽管有效的精确导航系统已越来越普及，但本报告中介绍的具有成本效益且精确的计算机辅助设计/计算机辅助制造手术导板系统可为大型鼻腭管囊肿的安全摘除提供支持。
