Clinical effect of excise epiglottis cyst by CO2 laser and high frequency under micro-laryngoscope / 中国内镜杂志

ABSTRACT

Objective To compare the clinical feasibility of excising epiglottis cyst by CO2 laser and high frequency under laryngomicroscope. Methods 44 cases with epiglottic cysts were divided into two groups, with 22 cases in observation group (OG) and also 22 cases in control group (CG). All patients were operated by a laryngomicroscopic surgery under a general anesthesia, while cases in OG under CO2 laser and patients in CG under high frequency electric knife to remove the cyst. Then, analyse and compare the clinical feasibility. Results The average operating time is significantly shorter , and the VAS of sore throat is obviously lower in OG than that in CG. Thanks to the accurate and precise operation by CO2 laser, the epiglottis cysts are able to be removed intact, the surrounding tissues and epiglottic cartilage are better protected. There is no recurrence in both groups. Conclusion The operation performed with CO2 laser under micro-laryngoscope holds such advantages as accurate and easy to operate, better protect cyst wall, and fewer side hurting.
