Bilateral recurrent laryngeal nerve paralysis diagnosed using dynamic
digital radiography during the COVID-19 pandemic
Dynamic digital radiography (DDR) is a motion-detective technique with
high temporal resolution. Flexible laryngoscopy is a common modality for
observation of the larynx, but it is aerosol generating. DDR is an easy
and less risky screening test for diagnosis of recurrent laryngeal nerve
paralysis during the COVID-19 pandemic.
