Vocal fold paralysis in subacute thyroiditis.

Vocal fold paralysis is associated with involvement of the vagus nerve or the recurrent laryngeal nerve between the jugular foramen and the entry point into the larynx. Malignancies of the thyroid are a frequent cause, but vocal fold paralysis is also found in certain benign diseases. In a series of 1,200 cases, the incidence of the association between paralysis and benign thyroid disease was 0.69%. In this paper we report a case of vocal fold paralysis associated with a benign thyroid condition.
