Objective To compare the clinical efficacy of resecting epiglottic cysts using low-temperature plasma scalpel versus ultrasonic scalpel under suspension laryngoscopy.

Methods A total of 120 patients with epiglottic cysts were selected and divided into plasma group and ultrasonic scalpel group, with 60 cases in each group. The plasma group underwent resection of epiglottic cysts with low-temperature plasma scalpel under suspension laryngoscopy, while the ultrasonic scalpel group was treated with ultrasonic scalpel under suspension laryngoscopy. The operation time, the time from postoperation to complete wound healing, and the amount of bleeding during treatment were recorded. Pain levels at 1, 3, and 5 d after treatment, as well as the effectiveness of treatment and complication rates one month later were compared between the two groups.

Results The operation time and blood loss in the plasma group were lower or shorter than those in the ultrasonic scalpel group(P < 0.05). The wound healing time in the plasma group was shorter, postoperative pain was less, and the incidence of complications was lower in the ultrasonic scalpel group compared to the ultrasonic scalpel group (P < 0.05).

Conclusion Under suspension laryngoscopy, the low-temperature plasma scalpel is more effective in treating epiglottic cysts than the ultrasonic scalpel, which can shorten operation time and reduce blood loss, alleviate pain, and decrease the rate of complications.
