Background. The COVID-19 pandemic has altered all aspects of how the healthcare system is organized, and impacted patients with head and neck cancer (HNC), who delayed diagnosis and treatment. The result was the increased admission of patients with severe dyspnea and a need for tracheotomy due to extremely advanced HNC. The aim of this study wasevaluate the characteristics of two multi-center cohorts of HNC patients admitted for dyspnea.Methods..The therapeutic activity of four University Departments of Otolaryngology was studied over two time periods: September-February 2019/2020 and 2020/2021.Results. A group of 136 HNC patients who underwent tracheotomy in two time cohorts, pre-COVID-19 (N=59) and COVID-19 (N=77), were analyzed. The mean tracheotomy incidence proportion was 1.82% (SD: 1.12) for the pre-COVID-19 and 3.79% (SD: 2.76) for the COVID-19 period. A rise in emergency dyspnea was observed in the COVID-19 cohort. In the pre-COVID-19 period, 66% of patients presented with symptoms for more than a month in comparison to 78% of patients in COVID-19 times (p=0.04). The number of tracheotomies performed under general anesthesia dropped in favor of local anesthesia during COVID-19 (64% vs. 56% respectively) due to extremely advanced HNC. In the COVID-19 cohort, most patients received a telemedicine consultation (N=55, 71%) compared to the pre-COVID-19 period (N=14, 24%).Conclusions. There should be a reorganization of the referral system, an adjustment of treatment capacity for an increased number of HNC patients, and a reserve for more extensive resection and reconstruction surgeries in ENT departmentsto not hamper future HNC treatment if there is another pandemic wave.
