Computed tomograms of the inner ear structures (n=175) of 150 patients (age 0-75 years) with unaffected temporal bones were studied in detail. It is shown that polyposition CT of the temporal bone is a non-invasive method of visualization of the osseous labyrinth structures: cochlea, vestibule, semicircular canals, aqueducts of the labyrinth and internal acoustic meatus which are reflected on tomograms in 100% cases irrespective of the patient age. Their age-related features are analysed. CT imaging was made in 65 patients with neurosensory hypoacusis of inherited and acquired genesis. The following causes of neurosensory hypoacusis and deafness were revealed: congenital malformation of the labyrinth of Mondini type, common cavity of the labyrinth, cochlear hypoplasia, dysplasia of the vestibule and semicircular canals, a wide aqueduct of the vestibule, stenosis of the internal acoustic meatus, bulboform enlargement of the inner acoustic meatus, neurinoma (schwannoma) of the hearing nerve, Langerhans-cell histiocytosis with affection of the labyrinth capsule, atypical cholesteatoma. The detected changes in the inner ear structures determine further treatment policy.
对150例（年龄0 - 75岁）颞骨未受影响患者的175份内耳结构计算机断层扫描图像进行了详细研究。结果表明，颞骨多体位CT是一种可视化骨迷路结构的非侵入性方法，这些结构包括耳蜗、前庭、半规管、迷路导水管和内耳道，在断层扫描图像中，无论患者年龄大小，这些结构在100%的病例中都能显示出来。分析了它们与年龄相关的特征。对65例遗传性和后天性神经感觉性听力减退患者进行了CT成像检查。发现了以下导致神经感觉性听力减退和耳聋的原因：Mondini型迷路先天性畸形、迷路共同腔、耳蜗发育不全、前庭和半规管发育异常、前庭导水管增宽、内耳道狭窄、内耳道球茎状扩大、听神经瘤（神经鞘瘤）、累及迷路包膜的朗格汉斯细胞组织细胞增多症、非典型胆脂瘤。内耳结构检测到的变化决定了进一步的治疗策略。
