The aim of this study was to demonstrate the impact of COVID-19 pandemic on the number and characteristics of head and neck cancer patients in two consecutive periods, pre-pandemic and pandemic. For this purpose, we performed a retrospective analysis of patients with primary carcinomas of head and neck mucosal sites, salivary gland tumors, as well as neck metastases. Two pre-COVID-19 years (2018-2019) and two pandemic years (2020-2021) were compared. ⋯ Despite these facts, there were no differences in TNM stages comparing two observed periods. Study results indicated that there was a statistically significant delay of surgical treatment for both cancer sites observed (oral cavity and larynx) during the COVID-19 pandemic. A survival study is necessary in the future to definitely reveal the true consequences of COVID-19 pandemic on treatment outcomes.
