Abstract:Objective To observe the clinical effect of low-temperature plasma ablation under visual anesthesia laryngoscope for the treatment of congenital epiglottic cyst in infants, and to explore the characteristics of this surgical method. Methods A total of 15 infants with congenital epiglottic cyst surgically treated in our hospital from Feb 2017 to Jan 2020 were included. The operative time, intraoperative blood loss and wound response were statistically analyzed. All the patients were followed up for more than half a year. Results Surgical treatment of congenital epiglottic cyst was successfully performed by low-temperature plasma ablation under visual anesthesia laryngoscope in all the 15 cases. The average operation time was (22.67±7.99) min, and the intraoperative blood loss was (3.47±1.60) ml. As for the wound response, mild edema of epiglottis was observed in 3 cases and moderate in 2. Postoperative follow-up for half a year revealed no recurrence. Conclusions Low-temperature plasma ablation under visual anesthesia laryngoscope is feasible for the treatment of congenital epiglottic cyst. With advantages of minimal invasion, safety and clear efficacy, this surgical method is worth promoting clinically for the treatment of congenital epiglottic cyst in children.
