摘　　要：目的:通过颞骨高分辨CT(HRCT)成像技术对内耳结构正常的先天性感音神经性聋患儿的耳蜗进行测量并分析,并探讨其在人工耳蜗植入术前评估以及选择合适的电极中的应用价值。方法:收集符合入组标准的120例先天性感音神经性聋患儿的颞骨HRCT图像,根据性别分为2组,其中男60例,女60例,用PACS软件测量耳蜗长径A(圆窗龛中心到骨外侧壁的最大距离),高度H(蜗轴高度),并计算耳蜗管长度,对数据进行可重复性评价、组间比较。结果:各组测量值在不同测量者间有较好的一致性,男性患儿的耳蜗长径为(8.55±0.31)mm,高径为(4.57±0.28)mm,耳蜗长度为(27.59±1.23)mm;女性患儿耳蜗长径为(8.45±0.32)mm,高径为(4.42±0.34)mm,耳蜗长度为(27.20±1.17)mm。男性患儿的耳蜗长径、高径、蜗管较女性长,差异有统计学意义(P<0.05)。结论:测量耳蜗的长径、高度以及计算耳蜗管的长度,可选择合适长度的电极或者定制个性化电极,是人工耳蜗植入术前的一种简单有效的评估方法。Objective：The cochlea of children with congenital sensorineural hearing loss with normal inner ear structure was measured and analyzed by high-resolution temporal bone CT（HRCT）imaging technique,its application value before cochlear implantation was evaluated and the appropriate electrode was selected.Method：We collected temporal bone HRCT images of 120 patients with congenital sensorineural hearing loss,according to gender divided into two groups,including 60 males and 60 females.We used the PACS software to measure the distance A（the largest distance from the round window to the lateral wall）and the distance H（height of the cochlea）and calculate the cochlear duct length.Reproducibility of these data were evaluated and the results between the different groups were compared.Result：Measurement of parameter values between the intraobserver and interobserver showed great reproducibility.In the male children group,the measured values are shown as distance A[（8.55±0.31）mm],distance H[（4.57±0.28）mm]and the cochlear duct length（CDL）[（27.59±1.23）mm];and in the female children group,the measured values are shown as distance A[（8.45±0.32）mm],distance H[（4.42±0.34）mm]and the cochlear duct length（CDL）[（27.20±1.17）mm].The A,H,and CDL of the male cochlea were greater than those of the female,the difference was statistically significant（P〈0.05）.Conclusion：Measuring the distance A and distance H of the cochlea and calculating the cochlear duct length CDL can be used to select a suitable length of electrode or to customize a personalized electrode.This is a simple and effective assessment method before cochlear implantation.
