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. An interactive, multimedia, case-based format will be utilized to highlight distinguishing features that may assist in predicting papilloma subtype and influence surgical planning.
