摘　　要：目的:报告一种新的CT测量方法,以预测面隐窝开放手术中圆窗龛暴露程度。方法:对40例需要开放面隐窝患者进行术前CT常规面窗线法和极限面窗线法两种方法的测量,与术中圆窗龛暴露程度大小进行对比分析。结果:两种CT测量方法对圆窗龛暴露程度预判的灵敏度和特异度无统计学差异,两者的Kappa一致性检验也呈较强相关性。结论:新的测量方法可以对面隐窝入路圆窗龛的暴露进行良好的预测,且在手术实践中,可以对圆窗龛进行最大暴露程度的预判。Objective: To report a new CT measurement to predict the exposure of round window niche during facial nerve recess surgery. Methods: Forty CT scans were measured by conventional facial-round window line and limiting facial-round window line method, and compared with the exposure of round window niche after the opening of the facial recess. Results: There was no significant difference in the sensitivity and specificity of the two CT measurement methods to predict the exposure degree of the round window niche, and the Kappa consistency test of the two methods also showed a strong correlation.Conclusion: The new measurement method can predict the exposure of the round window niche pre-operation, and in practice, it can predict the maximum exposure of the round window niche.
