[CT diagnosis of the nose-eye-related disease]

The findings of paranasal and (or) orbital CT scannings 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 lesions and 12 fibrous dysplasia. The combined use of bony windows and soft tissue windows were the most effective methods of accurately detecting nose-eye-related 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.
