Abstract
Sinonasal malignancies are a unique subset of head and neck cancers that necessitate close monitoring due to high local recurrence rates. Surveillance consists of a combination of endoscopy, imaging, and patient-reported symptomatology, but no standardized surveillance protocols currently exist. Strategies historically have been based on guidelines for other head and neck malignancies; however, the unique anatomical and histologic presentation of sinonasal malignancies presents challenges. This review discusses the literature surrounding the utility of each of the different surveillance modalities and highlights techniques under investigation to aid clinicians in optimizing the surveillance of sinonasal malignancies.
