Abstract: Objective: To retrospectively analyze the results of diagnosis and treatment and enhance the diagnostic and therapeutic level of nasoorbit related diseases. Method: Thirtyfive cases of nasoorbital diseases were analyzed retrospectively. Results: Of the 35 cases, rhinogeous orbital phlegmon was found in 6, traumatic nasoorbital and optic canal fracture in 4, mucocele of nasal sinus in 11, inverting papilloma of nasal cavity and nasal sinus in 3, and malignant tumor in 11. The main pathologic characteristics were as follows: bony absorption of orbit wall in inflammation disorder; compression, displacement and absorption of orbit wall in benign tumor; and bony destruction in malignant neoplasm. Conclusions: Nasal and orbital organs are closely anatomically related. CT and MRI are important in early diagnosis and treatment of nasoorbital related diseases. Treatment for benign tumors is mainly by operation, while malignant neoplasms should be treated by combination of operation and radiotherapy, etc.
