Whether vocal cord paralysis can heal on its own depends mainly on the cause of vocal cord paralysis. Vocal cord paralysis should be treated promptly and not wait for it to heal on its own. The activity of the vocal folds is mainly governed by the recurrent laryngeal nerve, and if the recurrent laryngeal nerve is damaged, it can cause vocal cord paralysis. Common causes of recurrent laryngeal nerve damage include thyroidectomy and laryngeal surgery that damages the recurrent laryngeal nerve, which can’t be cured by itself. Acute laryngeal nerve inflammation caused by viral infections may heal on its own, but the chances are relatively small. When vocal cord paralysis occurs, patients are recommended to go to the hospital in time, and after a systematic examination by a professional doctor to make a clear diagnosis and standardize the treatment for the cause and type of symptoms.
