Endoscopic laser medial arytenoidectomy for bilateral vocal fold paralysis has the advantage of preserving the structure and the position of the vocal fold, contrary to a transverse cordotomy or total arytenoidectomy. Our objective was to evaluate the functional results of this procedure. This is a prospective non-randomized study. Twenty patients were included: five patients had a tracheotomy preoperatively and 15 patients had dyspnea on exertion. Acoustic voice measurements, spirometric parameters and the voice handicap index 120 (VHI), were evaluated 1 week before surgery and 3 months after. All the five patients with tracheotomy were successfully decannulated. Acoustic records and VHI were available for eight patients. Jitter and shimmer were worse (p = 0.0078), whereas the VHI was not significantly different after surgery. Spirometric records, available for six patients, were not modified. Endoscopic laser medial arytenoidectomy allowed decannulation and subjective improvement of quality of life in patients with bilateral vocal fold paralysis.
