American Rhinologic Society Expert Practice Statement: Surveillance Strategies for Sinonasal Malignancy

The goal of this American Rhinologic Society expert practice statement (EPS) is to summarize the best available evidence for surveillance strategies following definitive treatment of sinonasal malignancy. Topics discussed include components of surveillance, including endoscopy and imaging subtypes, frequency and length of surveillance, and highlights of some specific pathologies that warrant special consideration. This EPS was developed following the recommended methodology and approval process as previously outlined. A modified Delphi approach with a working group of practitioners was utilized to develop five statements and one proposed algorithm, and all six items reached consensus after two rounds of discussion and modification. These statements and accompanying evidence are summarized, along with an assessment of gaps in the literature to identify future research needs.
