本研究旨在确定先天性耳道闭锁(CAA)鼓管成形术后长期听力预后的有利预后因素。我们回顾了51耳接受鼓管成形术的CAA患者的术前、术后听力和影像表现。根据最后一次纯音测听计算术后气导阈值、骨导阈值以及气骨间隙(ABG)的平均值。随访期16~139个月。成功的听力结果定义为术后ABG为≤15分贝，或术后纯音平均≤为30分贝。多因素Logistic回归分析影响手术成功率的因素有：Jahrsdofer分级系统总分、手术年龄和中耳的大小，包括砧椎关节角度、中鼓室高度、中鼓室宽度、中鼓室深度、中鼓室面积、中鼓室容量、可重建外耳道直径和可重建外耳道高度。听力恢复成功者24耳(47.1%)。多因素Logistic回归分析显示，EAC面积为72.3mm2(P=0.006)，其次是中鼓室深度为5.5mm2(P=0.013)，鼓室高度为4.6mm2(P=0.016)，EAC直径为9.5mM(P=0.029)。总之，可重建的EAC和中鼓室的大小对于预测CAA鼓管成形术后的长期良好听力结果是重要的。
The present study aimed to determine favorable prognostic factors for long-term postoperative hearing outcome after canal-tympanoplasty for congenital aural atresia (CAA). We retrospectively reviewed pre and postoperative hearing results and image findings of 51 ears with CAA performed by canal-tympanoplasty for primary repair. Averages of the postoperative air and bone-conduction thresholds, and the air–bone gap (ABG) were calculated from the last pure-tone audiometry. Follow-up duration ranged from 16 to 139 months. A successful hearing result was defined as a postoperative ABG of ≤15 dB, or a postoperative pure-tone average of ≤30 dB. The influence of the following factors on the success of surgery was assessed by multivariate logistic regression analysis: total Jahrsdoerfer grading system score, age at surgery, and dimensions of middle ear including incudostapedial joint angulation, mesotympanic height, mesotympanic width, mesotympanic depth, mesotympanic area, mesotympanic volume, reconstructable external auditory canal (EAC) diameter, and reconstructable EAC height. Successful hearing outcomes were achieved in 24 of 51 ears (47.1 %). A multivariate logistic regression analysis showed that an EAC area >72.3 mm2was the most significant favorable predictive factor (P= 0.006), followed by mesotympanic depth >5.5 mm (P= 0.013), mesotympanic height >4.6 mm (P= 0.016), and EAC diameter >9.5 mm (P= 0.029). In conclusion, the size of the reconstructable EAC and mesotympanum is important for predicting long-term favorable hearing outcome following canal-tympanoplasty for CAA.
