Thyroid Nodule Microwave Ablation

Nonsurgical treatment of Benign Thyroid Nodules


Thyroid nodules are solid or fluid-filled lumps that form within your thyroid gland. Traditionally, surgical intervention was the primary treatment method for these nodules.

Thyroid microwave ablation a nonsurgical, minimally invasive, outpatient procedure that uses heat to shrink thyroid nodules, has now become an increasingly popular treatment option for patients with benign thyroid swelling.

A thin needle (microwave antenna) is inserted through the skin, directly into the thyroid nodule under local anesthesia and using ultrasound guidance. Once in position, the microwave antenna is activated to heat and destroy the abnormal thyroid tissue. The antenna may then be repositioned under ultrasound guidance to ensure complete ablation.

After the procedure – small incision on skin is then covered with bandages with no sutures. The patient is discharged within 3-4 hours after the procedure.



Before recommending microwave ablation treatment (MWA), a Fine Needle Aspiration Cytology of the thyroid nodule (FNAC) is required to confirm its benign nature.


Patients having the following symptoms are ideal candidates for this procedure –
