Simple Summary Sinonasal cancers are rare. Surgery is often the first step of the therapeutic strategy, possibly complemented by adjuvant therapies. Surgical excision can be performed by an open approach with external incision, by an endoscopic approach using the nasal fossa as a surgical corridor, or by a combination of both. This article describes the main surgical techniques that can be used for the management of sinonasal cancer and reviews the criteria that lead to the choice of one technique over another. Abstract Surgery plays an important role in the treatment of sinonasal cancer. Many surgical approaches have been described, including open, endoscopic, or combined approaches. The choice is based on several criteria: general criteria related to the oncological results and morbidity of each technique, specific criteria related to the tumor (tumor extensions, tumor pathology), the patient, or the surgeon himself. The aims of this review are (i) to provide a complete overview of the surgical techniques available for the management of sinonasal malignant tumors, with a special focus on recent developments in the field of transnasal endoscopic surgery; (ii) to summarize the criteria that lead to the choice of one technique over another. In particular, the oncological outcomes, the morbidity of the different techniques, and the specificities of each histologic subtype will be discussed based on a comprehensive literature review.
