ABSTRACT

Objective To comparison curative effects between radiofrequency coblation and CO 2 laser in treat‐ment of early glottic carcinoma .Methods A total of 104 patients with early glottic cancer (Tis ,T1a ,T1b ) were treated in our department from October 2007 to December 2012 .Among them 64 cases underwent radiofrequency ablation (radiofrequency group) while 40 cases underwent CO2 laser resection (CO2 laser group) .The operation time and the postoperative pain VAS scores were recorded .All of the patients were examined by electronic laryngoscopy and a‐coustic analysis in 1 week ,1 month ,3 months after surgery .Results The mean operation time of radiofrequency group was 8 .75 ± 1 .62(min)and CO2 laser group was 11 .82 ± 1 .51(min) .The radiofrequency group was better than CO2 laser group(P 0 .05) .The mucosal recovery of radiofrequency group in 1 month after surgery was better than the CO2 laser group (χ2 = 13 .842 ,P 0 .05) .All of the patients had not underwent tracheotomy .They did not have cough ,dyspnea ,severe pain ,hemoptysis ,serious compli‐cations after surgery .Conclusion Both radiofrequency coblation and CO 2 laser are safe and effective surgical meth‐ods in the treatment of early glottic carcinoma .The operation time of radiofrequency coblation is shorter than CO 2 laser surgery .The mucosal recovery in 1 month after surgery and acoustic recovery of radiofrequenay coblation are all better than that of the CO2 laser surgery .
