The role of endoscopic laterofixation of the vocal cord in the treatment of bilateral abductor paralysis.

Different techniques were compared in management of 36 patients with bilateral abductor paralysis of the vocal cords. Ten patients were treated by microsurgical arytenoidectomy through a mid-line thyrotomy, with successful decannulation in only three. Fifteen patients were treated by endolaryngeal microsurgical arytenoidectomy, with failure to decannulate four cases. The procedure of endoscopic laterofixation of the vocal cord was used to treat 11 patients. Ten patients had an adequate long-lasting airway with a socially acceptable voice function. One patient had a revision surgery and was successfully decannulated. The technique was found to be a reliable option in the management of bilateral abductor paralysis. It is a modifiable procedure with a feasibility to adjust the position of the vocal cord under endoscopic control. It can be combined with endolaryngeal arytenoidectomy if the gain in the airway size produced by laterofixation is found insufficient.
