Clinical effect of CO2 laser resection of the epiglottic cyst under micro-laryngoscope suspension.

BACKGROUND: Epiglottic cysts are common diseases and have multiple morbidity, and traditional surgery causes intraoperative bleeding and postoperative recurrence. OBJECTIVE: To investigate the therapeutic effect of CO2 laser resection on epiglottic cyst when compared with traditional surgery. METHOD: Eighty patients with epiglottic cysts were randomly enrolled into the CO2 laser group (44 patients) and the high-frequency electrocautery group (36 patients). RESULTS: The CO2 laser group had a shorter operation time, less blood loss and fewer intraoperative ruptured cysts (p < .05). The duration of sore throat and the time before wound redness and swelling subsidence in the CO2 laser group were significantly shorter than those in the high-frequency electrocautery group (p < .05). Within one year after the operation, the incidence of epiglottic scar contracture in the CO2 laser group was significantly lower than that in the high-frequency electrocautery group (p < .05). CONCLUSION: The CO2 laser group has the advantages of minimally invasive, less bleeding, short operation time and less postoperative complications, and it is worthy of applying as clinical routine to treat epiglottic cysts.

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

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.
