摘要: 目的: 探讨计算机导航技术在口腔颌面部异物取出手术中的临床应用及对手术的指导意义,评价其临床效果。方法: 从2014年1月~2016年12月我院共收治的5例口腔颌面部异物患者。术前均行CT或CBCT扫描,将CT或CBCT扫描数据以DICOM格式导入导航系统,进行三维重建,用于术前规划和术中导航。观察术中导航的精确度,手术时间和患者术后反应,评价计算机导航在颌面部异物取出手术的临床效果。结果: 在计算机导航的辅助下,5例患者共发现28个异物:5个玻璃碎屑,16个小弹片,7个金属碎片。其中1例金属碎片因参考架松动未能精确定位,重新固定参考架后,所有异物均精确定位并通过微创的方法成功取出。导航误差<1 mm,手术时间缩短,患者术后均未出现并发症。结论: 计算机导航技术不但对颌面部异物精确定位,而且减少了手术时间,减轻了患者的术后并发症,增加了手术的精确度和安全性,对口腔颌面部异物取出手术具有重要的临床应用价值。

Abstract: Objective: To explore the clinical application of computer aided navigation in removal of foreign bodies in the oral and maxillofacial regions and evaluate the clinical effect. Methods: From January 2014 to December 2016, 5 patients with foreign bodies in oral and maxillofacial regions were treated at Nanjing Stomatological Hospital. Preoperative CT or CBCT scanning were undertaken for all patients and the scanning data were imported to computer aided navigation system as digital imaging and communication in medicine (DICOM) for 3D reconstruction. The data were used for preoperative planning and intra-operative navigation. The clinical effect was evaluated by observing the accuracy of intra-operative navigation, the operation time, and the postoperative condition of patients. Results: With the computer aided navigation, a total of 28 foreign bodies were found in 5 cases, including 5 glass fragments, 16 splinters, and 7 metals. One metal fragments could not be accurately located due to the loose of navigation reference frame. After re-fixed the reference frame, all foreign bodies were removed by minimally invasive access without any complications, the accuracy of computer aided navigation was less than 1mm, and the operating time was shorten. Conclusion: Computer aided navigation technology not only can accurately locate the foreign body in maxillofacial region, but also reduce the operation time and the postoperative complications, increase the accuracy and safety of surgery. Computer aided navigation had significant clinical values in the removal of foreign bodies in the oral and maxillofacial regions.
