Congenital aural atresia poses a great challenge, even to a competent otologic surgeon, due to innumerable types of malformations affecting the conduction and perception of sound. Roentgenographic evaluation by plain roentgenography is inconclusive in most cases; polytomography is helping to some extent. Recent generations of high-resolution computed tomographic (CT) scanners are probably the best. Seven cases of unilateral and three cases of bilateral congenital aural atresia were evaluated with high-resolution CT. Subsequently, ten ears were operated on. Surgical findings were correlated with CT scan findings with respect to atresia plate, extent of pneumatization, ossicular anomalies, bony facial nerve canal, and inner ear. Use of CT scans bears considerable importance in the management of these types of cases. High-resolution CT scan, when targeted for maximal bony detail, is possibly the method of choice in congenital aural atresia when surgical correction is contemplated.
先天性耳道闭锁带来了巨大挑战，即使对于一位经验丰富的耳科外科医生来说也是如此，因为影响声音传导和感知的畸形类型数不胜数。普通X线摄影的X线评估在大多数情况下都没有定论；断层摄影在一定程度上有所帮助。新一代高分辨率计算机断层扫描（CT）扫描仪可能是最佳选择。对7例单侧和3例双侧先天性耳道闭锁患者进行了高分辨率CT评估。随后，对10只耳朵进行了手术。将手术结果与CT扫描结果在闭锁板、气化程度、听骨链异常、骨性面神经管和内耳方面进行了对比。CT扫描的应用在这类病例的管理中具有相当重要的意义。当以获得最大程度的骨质细节为目标时，高分辨率CT扫描可能是考虑进行手术矫正的先天性耳道闭锁病例的首选方法。
