Objectives : The aim of this study was to evaluate the effectiveness and feasibility of coblation resection for the treatment of laryngotracheal disease. Methods : We conducted a retrospective review, evaluating 7 patients with laryngotracheal disease treated using coblator. Information collected included demographic data of the patients, diagnosis, size and location of the disease, procedure time, the number of previous operation, and the postoperative complication. Results : Among the etiology, granulation is most frequent (n=4), followed by recurrent repiratory papillomatosis (n=2) and tracheal stenosis (n=1). The location of lesions was peristomal area (n=2), glottis (n=2), subglottis (n=2) and mid-trachea. Coblation resection could remove the lesions completely and there was no significant complication including local burn, bleeding, and hypertrophic scar. The procedure time was shorter than the previous operation using $CO_2$ laser. Conclusion : Coblation resection is an effective and safe method for layngotracheal disease and can substitute the classic method such as $CO_2$ laser.
