Abstract
Objectives: Congenital epiglottic cysts are rare disorders of the larynx with symptoms such as laryngeal stridor and inspiratory dyspnea and are life-threatening in severe cases. This study aimed to investigate the usefulness of low-temperature plasma radiofrequency ablation for congenital epiglottic cysts and provide a reference for clinicians to develop treatment options. Methods: The clinical data of children (n = 7, 4 males and 3 females) with congenital epiglottic cysts, who were admitted to the Second Affiliated Hospital of Wenzhou Medical University and Yuying Children’s Hospital from March 2018 to March 2023, were analyzed retrospectively. Following preoperative examinations, all patients underwent low-temperature plasma radiofrequency ablation under general anesthesia, and the curative effect was evaluated. Following surgery, regular patient follow-up examinations were conducted to monitor recurrence. Results: The age at the time of operation ranged from 1 day to 99 days, with an average of 37.57 ± 35.01 days. The surgical procedure was successfully completed in all the children; dyspnea disappeared and no surgical complications were observed. In addition, during the postoperative follow-up period of 6 months to 5 years, recurrence was not observed. Conclusions: Low-temperature plasma radiofrequency ablation is a safe and effective procedure for treating congenital epiglottic cysts and deserves clinical application and promotion.
