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

Abstract 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.
