[Endoscopic extralaryngeal approach subtotal arytenoidectomy in the treatment of bilateral vocal cord paralysis].Lin Chuang Er Bi Yan Hou Ke Za Zhi. 2004 Aug; 18(8):473-4.LC
To evaluate endoscopic extralaryngeal approach subtotal arytenoidectomy for the treatment of bilateral vocal cord paralysis.
Thirteen cases of bilateral median vocal cord paralysis was operated by endoscopic extralaryngeal approach unilateral subtotal arytenoidectomy. All of them had tracheostomy before. The airway was modified about 5-6 mm via endoscopic in operating. The airway was evaluated by fibro laryngoscopy, and the voice quality was assessed subjectively by the patients and the surgeon before and after surgery.
All cases were followed-up 6-36 months. The function of airway successfully restored, and the voice quality was kept satisfactory. All patients were decannulated after 8 to 15 days within the mean time 11.5 days post-operation. There were no granulation and no aspiration at the surgical site post operateally.
The operation of extralaryngeal approach unilateral subtotal arytenoidectomy in endoscopy is a better restoration of airway with satisfying voice and without aspiration after operation. The procedure is simple, reliable and efficient for treatment of patients with bilateral median vocal cord paralysis.
