With the onset of the COVID-19 crisis in late 2019, the health care systems of different countries are experiencing stressful conditions. Many patients need care in hospital wards and intensive care units (ICU). Head & neck cancers (HNC) are in a special condition in this pandemic. The main treatment in these patients is surgery. Most of these patients need care in the ICU, which is reduced in capacity in pandemic conditions. It's important to note that delays in the surgery of these patients make them non-operable and on the other hand increase mortality and morbidity. Numerous non-surgical alternative therapies have been proposed in these conditions, but there are fundamental questions about these suggestions. 1 How long should we look for alternative therapies? Because many countries are facing a second wave of the disease. 2 What's the effect of these alternative therapies and the delay in starting standard treatments in patients' survival? Different countries have different financial resources; many countries, patients face restrictions on receiving alternative therapies to standard treatments, and in non-pandemic conditions, long queues are given for non-surgical treatments such as chemo-radiotherapy. There are numerous guidelines to guide head and neck surgeons to the best choice in this situation. It seems that different countries have to make individual decisions based on the prevalence of COVID-19 and the financial resources and facilities of the health care system. In this review article, we have collected the opinions of world-renowned guidelines and institutions on how to treat HNCs during the pandemic.
