What is Ultrasound-Guided RFA?
Ultrasound-Guided Radiofrequency Ablation (RFA) is a minimally invasive procedure that uses thermal energy to destroy abnormal tissue such as benign thyroid nodules or selected endocrine tumors. Under continuous ultrasound imaging, a thin probe is inserted into the targeted lesion. Once in place, radiofrequency energy generates controlled heat that safely shrinks or eliminates the nodule without removing the gland itself. Unlike traditional surgery, RFA leaves the surrounding tissue largely intact and avoids the need for a neck incision, making it a valuable alternative for patients who want to preserve thyroid function and avoid surgical scars.
This procedure helps to:
Reduce the size of benign thyroid nodules.
Relieve pressure symptoms such as difficulty swallowing or breathing.
Improve cosmetic appearance caused by visible neck lumps.
Preserve thyroid function while treating nodules.
Provide an alternative for patients unable or unwilling to undergo surgery.
What to expect after Ultrasound-Guided RFA?
Recovery is typically quick, with most patients resuming daily activities within 24 hours. Since no surgical incision is made, discomfort is minimal, and complications are rare. Visible reduction in the size of the treated nodule usually occurs gradually over weeks to months.
- Mild soreness or swelling in the treated area.
- Possible temporary hoarseness due to local nerve irritation.
- Small bruising at the insertion site.
- Return to work and activities usually within 1–2 days.
- Progressive shrinkage of nodules seen on follow-up imaging.
