Radiofrequency Ablation (RFA) of Benign Thyroid Nodule

Radiofrequency Ablation (RFA) of Benign Thyroid Nodule - Treatments

Usually malignant thyroid nodules require surgical removal. Benign thyroid nodules associated with symptoms and/or cosmetic problems may be considered for treatment. One of the minimally invasive treatments is radiofrequency ablation (RFA). This involves insertion of a radiofrequency ablation needle through skin into the thyroid nodule under ultrasound guidance, and heating the nodule using energy from  electric current. The probe is moved within different parts of the nodule to irreversibly destroy parts of the thyroid nodule and eventually reduces its size over time. 

This procedure is well tolerated, and is usually performed under local anesthesia. This has the additional advantage of allowing monitoring for potential nerve injury which can cause hoarseness. At the end of the procedure, the needle will be removed and the insertion site will be dressed.  You should be able to go home after 4 hours of monitoring at the Interventional Radiology Centre recovery area. 

Other available options for management of benign symptomatic thyroid nodules include percutaneous laser ablation (PLA), high-intensity focused ultrasound (HIFU) as well as surgery. Your doctor will discuss with you the best course of treatment in your case.
