This article retrospectively analysed the data of all patients diagnosed as malignant tumours of the nasal cavity and sinuses by pathological section in all patients (including outpatients and inpatients) in our hospital from January 2008 to December 2017 (10 years) to discuss the nasal cavity The clinical characteristics of sinus malignant tumours, and the clinical characteristics (symptoms, signs, imaging examinations) of 35 cases of olfactory neuroblastoma with high incidence were analysed, and their treatment methods and prognosis were summarized for future nasal tumours. Provide clinical basis for prevention and treatment. In our department, 300 cases of malignant tumours of nasal cavity and sinuses were treated within 10 years. Age: 86 cases (28.6%) in the age group 50-59 years, occupying the first place, 55 cases (18.3%) in the age group 60-69 years, occupying the second place. By comparing the two groups A and B, the malignant tumours of the nasal cavity and sinuses the difference in age distribution of olfactory neuroblastoma is statistically significant. Of the 35 cases of olfactory neuroblastoma, 23 cases were diagnosed with nasal tumours on admission, 12 cases were initially diagnosed with nasal polyps (including 7 cases with haemorrhagic and necrotic nasal polyps), and 20 cases underwent rapid pathological definite diagnosis during the operation. Diagnosis for postoperative pathological returns. Based on the above analysis, the following conclusions can be drawn: 300 cases of malignant tumours of the nasal cavity and paranasal sinuses: age distribution tends to be younger, the overall incidence of males is higher than that of females, but the proportion of male and female olfactory neuroblastoma is equal, and the incidence of adenoid cystic carcinoma and sarcoma The incidence rate of females is higher than that of males, with the primary origin in the sinuses. Among them, the maxillary sinus is more common. Olfactory neuroblastoma, lymphoma and sarcoma are gradually increasing in malignant tumours of the nasal cavity and sinuses.
