Computed tomography (CT) was used to examine 50 patients (100 temporal bones) aged from 10 days to 60 years with healthy external acoustic meatus (EAM) and 53 patients (62 temporal bones) aged from 4 to 75 years with symptoms of acquired stenosis, atresia or obturation of the external acoustic meatus. Polyposition CT of the temporal bone including axial and coronary projections is the most informative method of visualization of the EAM bone part. In axial projection the assessment covers the anterior and posterior walls of the EAM, in the coronary one - the upper and the lower walls. In the presence of EAM changes, CT is able to characterize them (soft tissue, bone, size, position). In patients with EAM neoplasms CT of the temporal bone detects polyps of the acoustic meatus, glomal tumors, neurinomas of the facial nerve, inherited cholesteatomas, cancer of the temporal bone. The detected alterations in the EAM and other structures of the temporal bone determine further policy of treatment.
计算机断层扫描（CT）用于检查50例年龄在10天至60岁之间、外耳道（EAM）健康的患者（100块颞骨），以及53例年龄在4至75岁之间、有后天性外耳道狭窄、闭锁或闭塞症状的患者（62块颞骨）。颞骨多体位CT，包括轴向和冠状位投影，是观察外耳道骨质部分最具信息量的方法。在轴向投影中，评估涵盖外耳道的前壁和后壁；在冠状位投影中，评估涵盖上壁和下壁。当外耳道出现改变时，CT能够对其进行特征描述（软组织、骨质、大小、位置）。在外耳道肿瘤患者中，颞骨CT可检测出外耳道息肉、颈静脉球瘤、面神经神经鞘瘤、遗传性胆脂瘤、颞骨癌。外耳道及颞骨其他结构检测到的改变决定了进一步的治疗方案。
