The radiation dose and the anatomic detail of computed tomography (CT) and conventional tomography were studied in 18 patients with suspected acoustic neuroma, cholesteatoma, malignant tumor, and temporal bone fracture. It is concluded that CT is the technique of choice in patients suspected of having acoustic neuromas or malignant tumors of the temporal bone, while hypocycloidal tomography should be used to evaluate pateints with otosclerosis, small cholesteatomas, and inflammatory disease of the middle ear. For diagnosing fractures and large cholesteatomas, CT and conventional tomography are complementary.
对18例疑似听神经瘤、胆脂瘤、恶性肿瘤和颞骨骨折的患者进行了计算机断层扫描（CT）和传统断层扫描的辐射剂量及解剖细节研究。得出的结论是，对于疑似患有颞骨听神经瘤或恶性肿瘤的患者，CT是首选技术，而对于患有耳硬化症、小胆脂瘤和中耳炎性疾病的患者，应使用亚摆线断层扫描进行评估。对于诊断骨折和大的胆脂瘤，CT和传统断层扫描是互补的。
