Causes And Risk Factors Associated With Vocal Cord Paralysis

Certain Infections

Certain infections may produce temporary or permanent paralysis of one of the vocal cords. For example, research has shown the Epstein-Barr virus, herpes, and Lyme disease lead to inflammation that can cause direct damage to the nerves serving the larynx. Viral or bacterial infections that inflame or injure the vagus nerve, which branches off into the larynx, may also result in vocal cord paralysis. Some research suggests the common cold could also trigger this condition. To diagnose infections that impact the vocal cords, doctors will perform a physical examination, and patients may also need to have blood tests, x-rays, or other advanced imaging studies. Depending on the cause of the infection, antibiotics, antifungal medicine, or intravenous infusions may be beneficial in clearing the infection from the body.
