  • Title: CO2 laser treatment of bilateral vocal cord paralysis in adduction.
    Author: Motta S, Moscillo L, Imperiali M, Motta G.
    Journal: ORL J Otorhinolaryngol Relat Spec; 2003; 65(6):359-65. PubMed ID: 14981330.
    Abstract:
    This study presents results obtained from 83 patients with bilateral vocal cord paralysis in adduction treated between 1982 to 2001, with CO(2) laser microlaryngoscopy. In relation to the different types of surgery followed, three distinct treatment groups were included: group 1 (1982-1984) included 5 patients treated with vaporization of the vocal process of the arytenoid and the homolateral posterior third of the true vocal cord. Group 2 (1983-1990) contained 19 patients who were treated with arytenoidectomy and removal of the homolateral posterior half of the true vocal cord and group 3 (1990-2001), including 59 patients who were treated with arytenoidectomy and removal of the homolateral posterior half or two thirds of both the true and false vocal cord. Functional results were assessed by means of spirometry, spectrography and aerophonic examinations performed at 5, 90, 180, and 240 days postoperatively. The results show that removal of the posterior third of the true vocal cord and false vocal cord, combined with arytenoidectomy, is the surgical treatment of choice to resolve respiratory insufficiency in these patients.
