[Korner's septum and congenital aural atresia].
OBJECTIVE
To discuss the anatomic characters and clinical importance of aural atresia coexisted with Korner's septum.


METHODS
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.


RESULTS
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.


CONCLUSIONS
The high resolution temporal bone CT is indispensable to the operation of aural atresia coexisted with Korner's septum.
