影像导航在有骨性解剖变异的慢性鼻-鼻窦炎手术中的应用

目的：评价分析影像导航系统在有骨性解剖变异的慢性鼻‐鼻窦炎鼻内镜手术中的作用。方法对影像导航系统辅助下行鼻内镜手术的慢性鼻‐鼻窦炎患者216例进行回顾分析，根据有无骨性解剖变异分成两组。对导航系统的精确性、术中使用影像导航的次数、术前准备时间、总的手术时间、术中术后的并发症及术后疗效等进行统计学分析。结果有骨性解剖变异组（186例）比无骨性解剖变异组（30例）在术中影像导航使用次数上更多（P ＜0．05）；不同骨性解剖变异组间使用影像导航次数进行比较，差异亦有统计学意义（P ＜0．05），存在多种解剖变异者使用导航次数最多。两组影像导航系统的精确性、术前准备时间、总的手术时间、术中术后的严重并发症及术后疗效进行比较，差异无统计学意义（P ＞0．05）。结论解剖变异不同，术中导航使用的次数不同，解剖变异越复杂，越能体现影像导航系统在鼻内镜手术中的作用。

Application of imaging navigation in chronic rhinosinusitis surgery with osteal anatomical variation

Objective To evaluate the role of imaging navigation （IV ） in the endoscopic surgery for chronic rhinosinusitis with osteal anatomical variation （OAV）. Methods According to the presence of OAV, 216 patients with chronic rhinosinusitis, receiving endoscopic sinus surgery, were divided into two groups, including OAV group （OAVG） and no OAV group （NOAVG）. Data including the accuracy of IV, the intraoperative using times of IV, the preoperative preparation time, the total operation time, and the intraoperative and postoperative complications, were analyzed statistically. Results Between OAVG （186 cases） and NOAVG （30 cases）, the intraoperative using times of IV were different, which of OAVG were more than NOAVG （P〈0. 05）. However, the accuracy of IV, the preop‐erative preparation time, the total operation time, the intraoperative and postoperative complications, and the postop‐erative curative effect, were similar respectively（P〉0. 05）. Among the groups with different OAV, the intraoperative using times of IV were also different（P〈0. 05）. Conclusion The intraoperative using frequence of IV might be dif‐ferent among patients with different OAV. The more complex of OAV, the better personification of the role of IV system.
