Abstract Objective: To explore the value of CT findings in the diagnosis and management of sinonasal malignancies. Methods: Fifty cases of coronal CT findings in sino-nasal malignancies were analysed retrospectively, and treatment planning were made depending on the CT manifestations. Results: All of the tumors were diagnosed under endoscopy. The rates of squamous cell carcinoma, melanoma, adenoid cystic carcinoma, olfactory neuroblastoma, lymphoma, and other malignancies were 30.0%(15/50), 14.0%(7/50), 14.0%(7/50), 8.0%(4/50), 14.0%(7/50) and 20.0%(10/50), respectively in which 66.7% of the squamous cell carcinomas invaded maxillary sinus; Most of the melanoma originated from nasal cavity, 71.4% of which invaded ethmoid sinus; Most of the olfactory neuroblastoma originated from nasal cavity, 100.0% of which invaded ethmoid sinus; 28.6% of the lymphoma invaded both nasal cavities, also can occur in each of the sinuses. To select treatment method based on coronal CT findings: 30.0%(15/50) of the tumors were removed under endoscopy; 26.0%(13/50) of the patients were treated with chemotherapy or radiotherapy after diagnosed under endoscopy; 14.0%(7/50) of the tumors were removed with Caldwell-Luc operation combined with endoscopy; 20.0%(10/50) of the tumors were removed through nasal lateral approach combined with endoscopy; 10.0%(5/50) of the tumors needed to remove the partial or complete maxillary bone. Conclusion: The lesions and invasions of sino-nasal malignancies could be shown clearly on coronary CT of the nasal sinus, which has great value in the diagnosis and treatment selection of sino-nasal malignancies.
