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相结合，层厚2mm或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，各鼻窦均有素及，其中以筛窦最多（18例），炎性病变鼻眼病变沟通方式以眶壁骨质吸收破坏为主（15例）。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（70例）。恶性肿瘤界眼病变的沟通方式以骨质破坏为主（58／68例，85．3％）。良性肿瘤及粘液囊肿主要为眶壁受压移位、骨吸收破坏。12例骨纤维异常增殖症则以病变骨质增厚造成眼眶、视神经管、眶上下裂及易窦狭小变形为主。外伤骨折120例中均为鼻窦与眼壁共壁所致，骨折多累及邻近结构骨折。提示CT检查能明确显示病变的发病部位、浸及范围和沟通方式，对临床诊断、选择治疗方式和估计预后有重要临床价值。
According to the CT examination data of 283 cases of clinically or pathologically confirmed nose-eye-related diseases, the imaging features of the disease and its occurrence and development of certain laws were explored. The main method is the combination of bone window and soft tissue window technology, layer thickness 2mm or 5mm, layer spacing 5mm, if necessary, line enhanced scan. The results showed that in all 23 cases involving orbital inflammatory lesions, the sinus are both known and, of which the largest number of ethmoid sinus (18 cases), inflammatory lesions of nasal lesions pathways orbital bone destruction mainly of bone destruction (15 cases) . 128 cases of tumor lesions involving the eyes, sinus, which also involved the ethmoid sinus up to (70 cases). The main way of communicating with malignant tumor was ocular bone destruction (58/68 cases, 85.3%). Benign tumors and mucoceles are mainly displaced orbital pressure, bone destruction. 12 cases of fibrous dysplasia with bone lesions caused by thickening of the orbit, the optic canal, supraorbital fissure and the main sinus-type small deformation. Traumatic fracture in 120 cases were caused by common sinus wall and wall, the fracture involving multiple adjacent structures fracture. Tip CT examination can clearly show the location of the lesion, immersion and range and communication, clinical diagnosis, selection of treatment and prognosis of important clinical value.
