Thyroid Nodule Radiofrequency Ablation
Thyroid nodules are fairly common and are seen in approximately 30% of adults undergoing ultrasound scan of the neck. These can be benign or cancerous, with majority of the nodules being benign in nature. Ultrasound scan followed by fine needle aspiration sampling (FNAC) are done to decide on nature of the nodule.
Surgical resection is the standard treatment for malignant nodules. Benign nodules require follow-up on a long term basis; especially if they grow in size or show atypical features on ultrasound scan.
One of the latest techniques introduced for treating these patients is radiofrequency ablation (RFA) of thyroid nodules. This is a minimally invasive technique that involves introducing a small special needle under ultrasound guidance into the nodule. Heat energy is applied to the nodule using this needle with destruction of cells from within. The nodules gradually shrink in size or become stable/ smaller in size on follow-up.
The major advantages are as below
- It is done as day surgery procedure under light sedation
- Patients are discharged the same day
- Normal thyroid tissue adjacent to the nodule is preserved
- No surgical scar with quick recovery and back to full activity and normal lifestyle
