Initial Outcomes of Endoscopic CO2 Laser Posterior Cordectomy and Partial Arytenoidectomy Among Patients with Bilateral Vocal Cord Paralysis: A Case Series
Keywords:vocal cord paralysis, arytenoid, vocal cords, laser, carbon dioxide, tracheostomy, voice quality
Objective: To describe the initial outcomes of endoscopic CO2 laser posterior cordectomy and partial arytenoidectomy among patients with bilateral vocal cord paralysis in our institution.
Design: Case Series
Setting: Tertiary National University Hospital
Participants: 17 Patients
Results: Seventeen (17) patients who underwent transoral posterior cordectomy and partial arytenoidectomy using carbon dioxide laser were included in the study consisting of 14 females and 3 males. Iatrogenic injury was the most common cause of bilateral vocal cord paralysis in this subset of patients. Five patients who tolerated decannulation and another six who had no preoperative tracheostomy all reported subjective improvement in breathing. All of them were also observed to have resolution of stridor and increased respiratory comfort compared to their preoperative condition. The most common postoperative complication was granuloma formation at the medial arytenoidectomy site occurring only in 4 patients. None of the patients complained of aspiration episodes or dysphagia during the postoperative period.
Conclusion: Our initial experience with transoral endoscopic posterior cordectomy and partial arytenoidectomy using carbon dioxide laser has good postoperative outcomes among patients with bilateral vocal cord paralysis.
