Bilateral Vocal Cord Paralysis Requiring Long-term Tracheostomy After SARS-CoV-2 Infection

Abstract

Bilateral vocal cord paralysis can cause obstruction of glottic airflow, resulting in respiratory distress and the need for a surgical airway. We report a case of acute onset bilateral vocal cord paralysis in a healthy adolescent patient 9 days after a mild severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection. This 15-year-old patient presented with dyspnea, tachypnea, and stridor. A fiberoptic laryngoscopy revealed bilateral vocal fold paralysis with limited vocal cord abduction causing respiratory distress. A detailed set of diagnostic test results, including blood work, imaging, and a lumbar puncture, were all negative other than her new onset diagnosis of SARS-CoV-2 infection. The patient underwent tracheostomy placement with the subsequent resolution of her symptoms. Her vocal cord function remains impaired, and the patient continues to be tracheostomy-dependent 13 months after the initial presentation. SARS-CoV-2 infection has multiple well-established neurologic complications in children. The current case suggests that vocal cord paralysis may be an additional neuropathic sequela of the virus. Vocal cord pathology should be an important consideration when constructing a differential for children presenting with voice, swallowing, or breathing complaints after SARSCoV-2 infection.
