Results of open and endonasal approaches in surgical treatment of the most common malignant tumors of the paranasal sinuses and skull base

Malignant neoplasms of the paranasal sinuses and skullbase are rare. They account for 3—5% of malignant tumors of the head and neck and less than 1% of all malignant neoplasms. The main method of surgical treatment of these tumors is transfacial operations. Such operations lead to serious complications: cosmetic defects and scars on the face, wound infections, long recovery time, which leads to an increase in the duration of hospitalization and a delay in adjuvant treatment. Endoscopic endonasal surgery has significantly advanced, expanding the indications for use over the past 20 years. This technical progress has made this treatment method a real alternative to transfacial approaches in surgery for malignant neoplasms of the paranasal sinuses and skull base. Numerous studies have shown that survival outcomes with the endoscopic endonasal approach are comparable, and in some cases even better, than with the open approach. However, given the rarity of this disease, personalized choice of treatment tactics remains a priority today.
