“Thyroid on Fire”: Initial Experience of Microwave Ablation for Benign Thyroid Nodules

Introduction: Thermal ablation for benign thyroid nodules has recently gained popularity in India with a limited number of patients having undergone the procedure in this country. The objective of this study was to evaluate the safety and efficacy of thermal ablation in euthyroid benign thyroid nodules (BTN).

Method(s): This is a single-center study of 21 patients who underwent RFA and MWA in FNAC proven benign thyroid nodules between January 2020 and November 2022. The reduction in volume of nodule, cosmetic and symptomatic improvement, effect on thyroid function, and complications following ablation were assessed.

Result(s): A total of 30 BTN in 21 patients were ablated. The median volume reduction was 60% after a median follow-up period of 120 days, with symptomatic and cosmetic improvement (p < 0.0001). There were no major complications; one patient had self-limited transient voice change that recovered in 3 months.

Conclusion(s): MWA and RFA are safe and effective for BTN. Thermal ablation should be considered as an alternative in patients who cannot or do not want to undergo surgery.
