How is thyroid nodule ablation performed?
Thyroid nodule ablation uses heat to shrink or destroy thyroid nodules without surgery. The most common technique is radiofrequency ablation (RFA). Under local anesthesia and ultrasound guidance, a thin probe is inserted through the skin into the nodule. The probe emits controlled heat to target and break down the nodule tissue, while surrounding healthy tissue is preserved. This allows hormone secretion by the healthy tissue to continue unaffected. The procedure typically takes less than an hour, requires no stitches, and is performed on an outpatient basis — meaning patients can go home the same day. Over 12 months, the treated nodule(s) gradually shrinks, relieving symptoms and improving cosmetic concerns.
