计算机导航技术在口腔颌面部异物取出手术中的应用
|
Abstract:
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
