ABSTRACT

Sinonasal malignant tumors are characterized by high histological variability and complexity of the differential diagnosis. Currently, there are classifications of these tumors, which are based on their localization and involvement of various anatomical structures. However, generally accepted algorithms for treatment of this pathology have not yet been developed. This review describes the most important algorithms for treatment of the most common histological variants of sinonasal malignant tumors squamous cell carcinoma, adenocarcinoma, sinonasal undifferentiated carcinoma, esthesioneuroblastoma, adenoid cystic cancer, and sinonasal adenocarcinoma. The main problems in choosing the approach for treating these tumors are the lack of generally accepted resectability criteria and contradictions between oncological and neurosurgical indications for surgical treatment. Further research is needed to study the role of radiosensitizers and radioprotectors in comprehensive treatment of sinonasal malignant tumors.
