Altered laryngeal function following thyroidectomy.
The laryngograph was used to record and compare the voice changes in 11 thyroidectomy patients and 14 controls. The frequency histogram was studied and the change in its spread following surgery used to identify abnormal vocal fold movements due to recurrent laryngeal nerve damage. It also demonstrated changes which occur in thyroidectomy patients and not in patients having other operations. The possible causes include external laryngeal nerve damage.
