Abstract

Lipomas, common benign tumors, may cause discomfort and cosmetic concerns. Radiofrequency ablation (RFA) and microwave ablation (MWA) is a minimally invasive treatment gaining popularity. This report examines the efficacy of RFA and MWA in treating neck lipomas. Two cases of RFA and MWA for neck lipomas were evaluated over 6 months. RFA achieved 53% volume reduction with partial ablation, while MWA resulted in remarkable reductions (81%, 86%, and 90% at 1, 3, and 6 months). Thermal ablation techniques are possibly used for managing lipomas. MWA is a more effective and safer minimally invasive option for treating neck lipomas compared to RFA, offering significant volume reduction and potential for broader clinical application.
