RFA is a minimally invasive, non-surgical treatment.
Using ultrasound guidance, a tiny needle is inserted into the nodule.
Heat from an electrical current melts the nodule from inside out, turning it into scar tissue that shrinks over time

Thyroid nodule radiofrequency ablation
Ideal for patients with:
- Benign, predominantly solid nodules ≥ 3 cm
- Growing nodules or compressive symptoms (pressure, difficulty swallowing)
- Cosmetic concerns
Always confirmed benign by fine-needle biopsy first
- Local anesthesia – no general anesthesia
- Outpatient – go home same day
- No scar, no downtime
- Preserves normal thyroid – no lifelong hormone pills
- 50–97% volume reduction, max by 6 months
During the procedure, you’ll stay awake and may talk to ensure your vocal cords are safe.
Mild discomfort afterwards is normal. Shrinkage starts in 4 weeks, continues up to 6–12 months .”
If you have a large benign thyroid nodule, ask your doctor about RFA, a safe, low-risk alternative to thyroidectomy
