To determine the key image anatomical parameters that are relevant to cochlear implantation (CI) using temporal bone high-resolution computed tomography (HRCT) scans and to identify age group differences in order to provide image anatomical support for early CI.
The data of 346 temporal bone HRCTs of 173 children from 5 months to 18 years of age were retrospectively selected and reviewed. Parameters of the human temporal bone that are relevant to CI key surgical steps include mastoid thickness (MT), the facial recess width (FRW), and an angle representing the round window visibility. All measurements are performed on axial images.
There was no significant difference in the above morphological values by gender (p > 0,05). Two-sided FRW was not significantly different (p > 0,05), but MT and angle A were significantly different (p < 0,001). FRW and angle were independent of age (p > 0,05). However, MT had been found to exhibit postnatal development. The linear function of MT were calculated as y = 2463 × group(s) + 20,574 (p < 0,001).
Based on preoperative imaging analysis at different ages, middle ear development was stable at 5 months of age, allowing early CI in infancy with severe to severe hearing loss at this age. These data must be considered exploratory and more extensive clinical studies are needed.
利用颞骨高分辨率计算机断层扫描（HRCT）确定与人工耳蜗植入（CI）相关的关键影像解剖参数，并识别年龄组差异，以便为早期人工耳蜗植入提供影像解剖学支持。
回顾性选取并分析173例年龄在5个月至18岁儿童的346例颞骨HRCT数据。与人工耳蜗关键手术步骤相关的人类颞骨参数包括乳突厚度（MT）、面神经隐窝宽度（FRW）以及代表圆窗可见性的角度。所有测量均在轴位图像上进行。
上述形态学值在性别上无显著差异（p>0.05）。双侧FRW无显著差异（p>0.05），但MT和角度A有显著差异（p<0.001）。FRW和角度与年龄无关（p>0.05）。然而，发现MT呈现出生后发育。MT的线性函数计算为y = 2463×组（s）+ 20574（p<0.001）。
基于不同年龄的术前影像分析，中耳在5个月时发育稳定，允许对该年龄段重度至极重度听力损失的婴儿进行早期人工耳蜗植入。这些数据必须被视为探索性的，需要更广泛的临床研究。
