Oncologic outcome of multimodality treatment for sinonasal malignancies: An 18-year experience.

Purpose: The aim of this study was to retrospectively evaluate the oncologic outcomes of sinonasal malignancies (SNMs) of various histologic subtypes and investigate the impact of multimodality treatment on prognosis of SNM.

Methods: SNM patients treated with curative-intent surgery from 2000 to 2018 were included. The primary outcomes were overall survival (OS).
