This study of 34 normal ears was conducted in order to define more precisely the normal computed tomographic (CT) anatomy of the osseous external auditory canal. Great variability was found in canal configuration and its relationship to the temporal squama. The understanding of normal CT appearance of the various fissures along the anterior wall of the external canal is important to avoid mistaking fissures for fractures.
本研究对34只正常耳朵进行，旨在更精确地界定骨性外耳道的正常计算机断层扫描（CT）解剖结构。研究发现外耳道形态及其与颞骨鳞部的关系存在很大差异。了解外耳道前壁各裂隙的正常CT表现对于避免将裂隙误诊为骨折很重要。
