Left Vocal Cord Palsy Immediately After COVID-19 Despite No Tracheal Intubation.

The cases of coronavirus disease 2019 (COVID-19) typically present with pulmonary and upper respiratory tract symptoms, but may also present with neurologic complications. Because severe cases are often intubated or ventilated, there are some reports of vocal cord palsy associated with intubation; however, there are few reports of recurrent nerve palsy without intubation management. We experienced a case of left vocal cord palsy following COVID-19 in a healthy young male patient with no previous medical history. The patient became aware of hoarseness symptoms three days after he was found to be COVID-19 positive, and an endoscopic examination of the larynx revealed left vocal cord palsy. Since the patient had no previous medical history and there were no lesions that could cause recurrent nerve palsy on neck-thorax imaging, it was considered likely that the patient had unilateral recurrent nerve palsy due to acute inflammation caused by severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection. Medication was started and his hoarseness became relieved. In vocal cord palsy occurring after COVID-19 illness, it is necessary to consider the presence of both vocal cord palsy related to tracheal intubation and recurrent nerve palsy associated with SARS-CoV-2 infection.
