Introduction
Coronavirus disease 2019 (COVID-19) is a worldwide infection that led to more than 236,000,000 cases and 4,800,000 deaths as October 5, 2021.1 According to world regions, less than 20% of COVID-19 were severe-to-critical disease, which is defined as a condition with severe acute respiratory distress requiring mechanical ventilation.2 The proportion of survivors after severe or critical COVID-19 ranges from 20 to 62% regarding studies.3 Survivors may keep neurological and systemic postdischarge complications, e.g. breathlessness, psychological distress or cognitive impairments.4 The mid-to-long term otolaryngological complications of COVID-19 were poorly investigated at the exception of olfactory and gustatory dysfunctions.5 Recent studies reported swallowing disorders at post-intensive care unit (ICU) discharge,6 while others reported laryngeal injuries post-tracheostomy.7
The aim of this study was to investigate post-intubation laryngeal complications in severe COVID-19 patients.
