To discuss the anatomic characters and clinical importance of aural atresia coexisted with Korner's septum.
Fifty patients with aural atresia coexisted with Korner's septum were analyzed retrospectively, in which the reconstruction surgery was performed, and high resolution temporal bone CT scan in the coronal and axial plane were taken preoperatively.
Among 50 patients, 39 had well-developed Korner's septum. The others (11/50) had incomplete Korner's septum, which were porotic continued with antrums, under powerful microscopic inspection. The ossicular reconstruction was performed successfully in 41 patients, while that of the other 9 had to suspend because of displacement such as low tegmen and backward processus condylaris of mandible.
The high resolution temporal bone CT is indispensable to the operation of aural atresia coexisted with Korner's septum.
探讨合并科纳氏隔的外耳道闭锁的解剖特点及临床意义。
回顾性分析50例合并科纳氏隔的外耳道闭锁患者，均接受了重建手术，并于术前进行了颞骨高分辨率冠状位和轴位CT扫描。
50例患者中，39例科纳氏隔发育良好。其余11例在高倍显微镜下观察为科纳氏隔不完整，呈多孔状并与鼓窦相连。41例患者成功进行了听骨链重建，另外9例因如颅中窝底较低、下颌骨髁突后移等移位情况而不得不中止手术。
高分辨率颞骨CT对于合并科纳氏隔的外耳道闭锁手术不可或缺。
