Abstract:Abstract：Objective：To evaluate the efficacy and safety of low-temperature plasma radiofrequency ablation via suspension laryngoscopy for laryngeal and hypopharyngeal hemangiomas. Methods: A retrospective analysis was conducted on 27 patients with laryngeal or hypopharyngeal hemangiomas treated in our department between July 2014 and June 2023. All procedures were performed under general anesthesia with endotracheal intubation using plasma radiofrequency ablation. operative duration, intraoperative blood loss, and postoperative pain (assessed by Visual Analog Scale [VAS]) were recorded. Laryngoscopic follow-ups were conducted at 1 week, 2 weeks, 1 month, 3 months, 6 months, and 1 year postoperatively to evaluate treatment outcomes. Results: All 27 patients achieved favorable recovery with: Operative duration: 32.59 ± 14.83 minutes; Intraoperative blood loss: 35.56 ± 42.67 Ml, the median is 20 mL; Postoperative pain (VAS score): 2.26 ± 1.20 (mild pain). Only 1 patient experienced severe intraoperative hemorrhage requiring tracheotomy and ligation of the ipsilateral superior laryngeal artery. No other major complications (e.g., laryngeal stenosis, vocal cord paralysis) were observed. Conclusion：Low-temperature plasma radiofrequency ablation via suspension laryngoscopy is a safe and effective treatment for laryngeal and hypopharyngeal hemangiomas, characterized by short operative time, minimal blood loss, and mild postoperative pain. This technique is worthy of clinical promotion for its minimally invasive advantages and reliable outcomes.
