Résumé
Background and Objective: To evaluate the results of endoscopic laser medial arytenoidectomy (ELMA) for bilateral vocal fold paralysis. Study Design/Material and Methods: A prospective study was designed. 20 patients with bilateral vocal fold paralysis were included in this study. Five patients had a tracheotomy and all the other 15 patients had dyspnea on mild exertion. Acoustic and aerodynamic measurements, spirometric parameters and voice evaluation, were performed one week before surgery and 3 months after. Results: 18 bilateral ELMA were performed, and 2 unilateral. All patients improved subjectively in daily physical activities. The 5 patients with tracheotomy were decanulated post-operatively. No aspiration occurred after surgery. Jitter and Shimmer were altered (p=0.0078), whereas the voice quality subjective evaluations and spirometric objective evaluations did not show significant modifications after surgery. Conclusions: CO2 Endoscopic laser medial arytenoidectomy is a safe and efficient procedure, allowing subjective improvement of quality of life in patients with bilateral vocal fold paralysis, without degradation of voice quality.
