To report a new CT measurement to predict the exposure of round window niche during facial nerve recess surgery. 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. 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. 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.
报告一种新的CT测量方法，以预测面神经隐窝手术中圆窗龛的暴露情况。采用传统的面神经-圆窗线和限定面神经-圆窗线方法对40例CT扫描进行测量，并与面神经隐窝开放后圆窗龛的暴露情况进行比较。两种CT测量方法在预测圆窗龛暴露程度的敏感性和特异性方面无显著差异，两种方法的Kappa一致性检验也显示出强相关性。新的测量方法能够在术前预测圆窗龛的暴露情况，且在实际应用中能够预测圆窗龛的最大暴露情况。
