RESUMO
Most patients with bilateral vocal cord paralysis have a fairly satisfactory voice, but their airway is usually compromised. The management of such patients presents a challenge to the otolaryngologist-head and neck surgeon. Numerous surgical procedures have been developed in an attempt to improve the patients's airway insufficiency without leaving him with a breathy, weak voice. Arytenoidectomy is currently the most reliable method of treating patients with bilateral vocal cord paralysis. Although both endoscopic and external approaches have been described for performing an arytenoidectomy, the endoscopic technique is more desirable since it requires no incision and theoretically allows for the immediate assessment of airway size. The addition of the CO2 laser to the surgical armamentarium offers certain refinements to the technique of endoscopic arytenoidectomy. Eleven patients with bilateral vocal cord paralysis of the larynx have been treated by endoscopic laser arytenoidectomy by the authors utilizing a technique developed by the two senior authors and subsequently taught to over 200 participants of the CO2 laser workshops sponsored by the Department of Otolaryngology-Head and Neck Surgery at Northwestern University Medical School; 10 of the 11 patients have been successfully decannulated. The technique and problems of this operation will be discussed.
