Abstract
A total of 39 patients with bilateral post-thyroidectomy vocal cord paralysis in adduction underwent CO2 laser subtotal arytenoidectomies with removal of the posterior third of the false and true vocal cords. Total airway resistance (R tot) evaluated before and 4–10 months after surgery showed marked preoperative impairment before and significant improvement after surgery (P < 0.05). In five patients revision surgery was performed due to a progressive impairment of respiratory function. A variable degree of voice breathiness was observed after surgery; the maximum phonation time mean values were lower than normal and peak sound pressure levels 63 ± 5 dB. In three cases aspiration was present in the first postoperative days, but swallowing dysfunctions disappeared within 1 week. Subtotal arytenoidectomy with removal of the posterior third of the true and false vocal folds was found to be a satisfactory surgical treatment for bilateral vocal cord paralysis in adduction. However, further research is still needed to define the surgical procedure able to balance respiratory, phonatory and sphincteric functions optimally.
