Ultrasound-guided percutaneous radiofrequency ablation for benign thyroid nodules

The procedure

This procedure is usually done as an outpatient procedure, under local anaesthetic. A thin probe is inserted into the nodule using imaging guidance. The probe is attached to a device that delivers pulses of radiofrequency heat energy to destroy tissue in the nodule.

The aim of ultrasound‑guided percutaneous radiofrequency ablation is to be able to use smaller cuts than with 'open' surgery, so that there is less pain and scarring.
