To propose a numerical radiological scoring system of the pre-operative high-resolution computed tomography scan aiming to predict the surgical difficulty during cochlear implantation.
This was a retrospective study of 272 pediatric patients who underwent cochlear implantation in 3 tertiary referral centers from April 2017 to August 2019. The correlation was attempted between our proposed scoring system (consisting of 8 radiological features) and the intraoperative surgical difficulty both objectively and subjectively.
our proposed scoring system showed a statistically significant correlation with surgical difficulty and also the duration of surgery. Scoring 5 or more predicted the surgical difficulty with a sensitivity of 80.85% and a specificity of 92.13%. The absence of air cells around the facial recess was the most independent predictor of difficulty (P value = .002).
This proposed radiological scoring system is a simple reliable method to predict the difficulty which we may encounter during CI surgery. Scoring of 5 or more would predict intraoperative difficulty as opposed to less scoring which would predict a straightforward surgery.
提出一种术前高分辨率计算机断层扫描的数字放射评分系统，旨在预测人工耳蜗植入术中的手术难度。
这是一项回顾性研究，纳入了 2017 年 4 月至 2019 年 8 月在 3 家三级转诊中心接受人工耳蜗植入术的 272 例儿科患者。尝试将我们提出的评分系统（由 8 个影像学特征组成）与术中手术难度进行客观和主观的相关性分析。
我们提出的评分系统与手术难度和手术时间均具有统计学显著相关性。评分≥5 分预测手术难度的敏感度为 80.85%，特异度为 92.13%。面神经隐窝周围无气房是最独立的困难预测因素（P 值=0.002）。
该放射学评分系统是一种简单可靠的方法，可预测我们在 CI 手术中可能遇到的难度。评分≥5 分预测术中难度较大，而评分较低预测手术相对简单。
