Objective To explore clinical efficacy of CO2 laser,low-temperature plasma and electrotome on treatment of epiglottis cyst.Methods A total of 60 cases with epiglottis cyst treated in our department were randomly assigned into CO2 laser group,low-temperature plasma group,and electrotome group,with 20 cases in each group.Postoperative pain,recovery rate,recurrence rate,complication,and intraoperative bleeding were compared in three groups.Results The pain severity was the highest in the electrotome group,followed by the CO2 laser group,and low-temperature plasma group was the lowest.Recovery rate in CO2 laser group was approaching to the low-temperature plasma group,but the electrotome group was slower than above two groups.The blood loss was less in CO2 laser group and low-temperature plasma group,and more in electrotome group.No recurrence was found in CO2 laser group and low-temperature plasma group after 6 months to 3 years of followup,but there was one case with less amount of blooding,and one case complicated with epiglottis defect in the electrotome group.Conclusion The three surgical ways are the major methods for treatment of epiglottis cyst,and have better curative efficacy.Compared with electrotome,CO2 laser under micro-laryngoscope and low-temperature plasma have more advantages.
