Sinonasal papillomas encompass a diverse group of lesions with distinct clinical and histopathological features which impact management and prognosis. In this course we will review the subtypes of Schneiderian papillomas: exophytic, oncocytic, and inverted. The incidence, clinical presentation, and histopathological characteristics of each subtype will be discussed. Appropriate and tailored surgical treatment options will be evaluated in the context of a literature review to improve results and outcomes. The spectrum of surgical approaches, including extended endoscopic and open techniques, will be described and demonstrated with video. Adjuvant and experimental treatments for refractory papillomas will also be discussed. An interactive, multimedia, case-based format will be utilized to highlight distinguishing features that may assist in predicting papilloma subtype and influence surgical planning. Audience response questions will be implemented to facilitate participation.
