表面配准与解剖标志配准在鼻内镜导航手术中的应用比较

目的:评价表面配准和解剖标志配准技术在鼻内镜导航手术中应用的优劣。方法:在26例鼻内镜手术中进行导航,从准备时间、靶点误差这2方面比较其差别,并就导航手术的方便程度和应用价值进行分析。结果:26例鼻内镜手术均成功使用影像导航系统,术中均提供了准确的鼻内解剖定位,无并发症发生。表面配准组的平均准备时间为(8.5±1.9)min,解剖标志配准组为(6.5±1.7)min。表面配准组的鼻唇角靶点配准误差为(1.43±0.26)mm,中甲前端附着缘为(1.92±0.47)mm,下甲前端附着缘为(1.82±0.49)mm,下甲后端附着缘为(2.03±0.42)mm。解剖标志配准组中对应的靶点配准误差分别为(1.58±0.35)mm、(2.05±0.37)mm、(1.92±0.31)mm和(2.48±0.64)mm。术者对于导航方便程度的评价总体较高,完全不影响或略影响手术者24例(92.2%)。术者认为导航有使用价值或明显使用价值者22例(84.6%),其价值主要与靶点误差值有相关。结论:表面配准方法的精确度要优于解剖标志配准法,但解剖标志配准更简便,准备时间明显短于表面配准方法。Digipointeur导航系统使用方...

A comparison between anatomical landmark registration and surface registration for computer-assisted endoscopic sinus surgery

Objective:To evaluate the clinical advantage and disadvantage of anatomical landmark registration(ALR) and surface registration(SR) in computer-assisted endoscopic sinus surgery(CAESS).Method:Twenty-six patients were selected for the CAESS,the preparatory times and mean target registration errors(TRE) were recorded in order to compare the difference between them two,their convenience and their value were also analyzed.Result:CAESSs were successfully used in 26 cases without complications.The average prepara...
