Abstract: This study explored the diagnosis and differential diagnosis of rhinosinus sinuses with multiple CT signs and multiple signs combined in the diagnosis and differential diagnosis of rhinosinus fungal infections. A total of 107 patients with complete nasal sinus CT scan data and nasal endoscopic histopathological examination are selected with menstruation in the Department of Otolaryngology as the research objects. The gender, age, and CT signs are analyzed. The study showed that the CT signs of fungal infection of the nose and sinuses and other sinus diseases were statistically significant (P<0.05); multivariate logistic regression analysis showed that the soft tissues had high density and calcification in the soft tissues, adjacent to the sinus wall bone hyper-plasia and sclerosis, the lesion is located in the maxillary sinus, which is an independent risk sign; a combined drawing model of the three signs has the highest diagnostic value. Therefore, CT scan multiple signs are of great value for the diagnosis of rhinosinus fungal infections, which can im-prove the accuracy of diagnosis.

Key words: CT scan, multiple signs, rhinosinus fungal infection
