Abstract
Posterior glottic stenosis (PGS), of which the most common cause is tracheal intubation, is often misdiagnosed as bilateral vocal cord paralysis. We herein report a case of PGS that occurred after treatment with COVID-19 with long-term intubation. The patient underwent tracheostomy and endoscopic resection and showed improvement in dyspnea. The COVID-19 epidemic is expected to increase long-term intubation cases and cases of severe laryngeal injury, including PGS. We need tracheostomy in long-term intubated COVID-19 patients, just like other diseases, and an appropriate diagnosis and surgical treatment for PGS should be performed. When otolaryngologists encounter cases of bilateral vocal cord paralysis, it is necessary to keep in mind the possibility of PGS and laryngeal stenosis and pay attention to the history of COVID-19.
