Management of Adult Laryngeal Hemangioma With Low-Temperature Plasma Radiofrequency Coblation.

Objective: This study investigated the therapeutic effects of low-temperature plasma radiofrequency (LPRF) coblation on adult laryngeal hemangiomas (ALHs) using suspension laryngoscopy. Material and Methods : The clinical data of 23 patients with ALH treated by LPRF coblation were analyzed retrospectively. All patients underwent edge coagulation before ablation resection. Postoperative voice and swallowing were assessed. Results : The 23 ALHs were diagnosed clinically as 6 cavernous hemangiomas and 17 capillary fibroangiomas. All 23 cases achieved success after a single LPRF coblation, and there was no postoperative bleeding, dyspnea, dysphagia, dysphonia, or other complications. None required postoperative tracheotomy. The patients were followed for 1 year without recurrence. Before surgical intervention, only 2 (8.7%) of the 23 patients had mild (n = 1) or moderate (n = 1) dysphagia. Postoperative dysphagia was assessed at the 1- and 3-month follow-ups. At 1 month, 5 (21.7%) of 23 patients had mild dysphagia, including 3 (13.0%) reporting new mild dysphagia. However, at 3 months postoperatively, none of patients had any dysphagia. The mean Voice Handicap Index was 11.2 ± 3.7 preoperatively, 7.1 ± 2.8 at 1 month postoperatively, and 4.8 ± 3.1 at 3 months postoperatively; the mean maximum phonation time was 10.8 ± 3.7 seconds preoperatively and 12.6 ± 1.8 and 14.1 ± 3.9 seconds at 1 and 3 months postoperatively, respectively. Conclusions : LPRF coblation is an effective minimally invasive method for treating ALHs with better voice and swallowing recovery. Edge coagulation before ablation resection may reduce intraoperative bleeding.
