Abstract
Pending the emergence of appropriate techniques tor restoring functionally adequate mobility to a paralysed vocal cord, laryngeal surgeons must continue to rely on static cordal repositioning procedures to improve laryngeal function. This prospective study included 27 adults patients with bilateral abductor paralysis of the vocal cords, they were classified into 4 groups; the first group was treated by endoscopic laterofixation, the second group was treated by endoscopic microsurgical arytenoidectomy, the third group included the failure of the first and second groups and to whom combination of the laterofixation and arytenoidectomy was performed in two stages. The last group included patients treated by laser arytenoidectomy. Comparison of the outcome of these surgical procedures was carried out by using pulmonary function tests and vocal function evaluation.We considered a period of 6 months as a minimum period before judging a paralysis as being permanent which as a matter of fact was universally agreed upon in the literature.Regarding the postoperative glottic chink we found that glottic chink of 4-5 mm is sufficient for decannulation.
