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.
