鼻眼相关疾病的CT扫描诊断

根据２８３例经临床或病理证实的鼻眼相关疾病的ＣＴ检查资料，探讨该疾病的影像学特点及其发生、发展的某些规律。方法主要是用骨窗和软组织窗技术要结合，层厚２ｍｍ，５ｍｍ，层间距５ｍｍ，必要时行增强扫描。结果示２３例累及眼眶的炎性病变中，各鼻窦均有累及，其中以筛窦最多，炎性病变鼻眼病变沟能芭眶壁骨质吸收破坏为主。１２８例肿瘤性病变全部累及眼眶、鼻窦，其中亦以累及筛窦为最多。恶性肿瘤鼻眼病变的沟通方式以骨质

CT diagnosis of the nose-eye-related disease

The findings of paranasal and (or) orbital CT scanings of 283 cases who suffered from the nose-eye-related diseases were studied retrospectively in this paper. Of 283 cases, which were proved either by the operation or histopathology, 128 were neoplastic diseases, 120 were traumatic fractures, 23 inflammatory 1esions and 12 fibrous dysplasia. The combined use of bony windows and soft tissue windows were the most effective methods of accurately detecting nose-eyerelated disease. Meanwhile, vascular contrast were used for neoplastic lesions and some other diseases suspected of fungul nasal-sinusitis,mucocele or traumatic fracture so as to determine the degree and extent of the lesions. The results indicated that the bony destroy was the main diffusion way of the nasal,eye and cranial disease. The natural anatomic duct or openings often became the passage of inflammatory or neoplastic lesions from one organ to another. This study showed that CT scan can clearly demonstrate the degree and extent of the lesion of the nose-eye-related disease and the way of diffusion. The diagnosis of nose-eye-related disease should be established in the imaging analysis.
