title: Endonasal Endoscopic Surgery in the Management of Sinonasal and Anterior Skull Base Malignancies.
abstract: Sinonasal malignancies represent a rare subset of tumors with a wide variety of histopathologic diagnoses and overall poor prognosis. These tumors tend to have an insidious onset with non-specific symptoms which often leads to delayed diagnosis and advanced local disease at presentation. The principal goal of surgery is to obtain a negative margin resection. Open craniofacial techniques are well established in the management of sinonasal malignancies and remain the treatment of choice for many advanced tumors. Over the past couple of decades, there has been tremendous application of endoscopic techniques to skull base pathologies including sinonasal malignancies. For selected cases, endonasal endoscopic techniques can be performed with curative intent and reduced surgical morbidity and mortality. Here we discuss principles of surgical management of sinonasal malignancies, review the techniques of endonasal endoscopic resection of sinonasal malignancies, and highlight the importance of pathology in the multi-disciplinary management of patients with these complex lesions.
