ABSTRACT
Objective To investigate the use of suspension laryngoscopy CO2 laser combined with the placement of laryngeal stent for the treatment of the vocal cords adhesion.Methods A total of 21 patients with acquired vocal cords of adhesion patients(The causes were previous vocal fold surgery for benign lesions in 16 cases,the laryngeal surgery for recurrent papilloma in 4 cases,the laryngeal trauma in 1 case)were included in this retrospective study.Under general anesthesia with intubation,following glottis exposure under suspension laryngoscopy,a CO2 laser incision was performed under microscopy on the superior face of one vocal fold,from the anterior commissure to the posterior part of the web.The keel was placed into the larynx to the appropriate location and fixed with sutures.Results The keels were removed after 3 weeks of operation in 20 patients.The keels were removed after 2 weeks of operation because of subcutaneous emphysema in 1 patient.After a follow-up of 6 months,the reformation of the web happened in 1 case,while the remaining 20 patients recovered with normal triangle shaped anterior commissure anatomy and no granulation or scar tissue were formed.Conclusion Our study shows that the use of suspension laryngoscopy CO2 laser combined with the placement of laryngeal stent is successful for the treatment of the vocal cords adhesion.This procedure has the advantages of micro trauma to patients with avoiding laryngofissure,it provides simple effective treatment of vocal cords adhesion.
