A simple operation for bilateral vocal cord paralysis.

To reduce the laryngeal obstruction in bilateral vocal cord paralysis, a new method of laterofixation was developed. The method is technically simple and less traumatic than previously published methods. No peroperative tracheostomy is needed. During surgery two needles are inserted through the thyroid cartilage. A nylon thread is passed through the needles and the needles are then withdrawn. The thread thus forms a permanent loop around the vocal cord. The effects of the laterofixation on breathing and on the voice are documented by assessment of upper airway resistance and by two listening panels respectively. Thirteen patients have been operated upon so far. In most cases the breathing was improved and the influence on the voice was moderate and adjustable. If needed the possibility to perform a more extensive surgical procedure still remains. We suggest our method of laterofixation to be the first treatment of choice in patients suffering from bilateral vocal cord paralysis.
