Overview
Radiofrequency ablation (RFA) of the thyroid is a minimally invasive procedure used to treat thyroid nodules or tumors. This is done by using radiofrequency (RFA) energy to generate heat and destroy abnormal tissue. It is an effective option for patients with benign thyroid nodules that cause symptoms or cosmetic concerns. This procedure is performed under local anesthesia and offers a quick recovery time.
While laser ablation and microwave ablation are options for treatment, all thermal ablation (microwave, RFA, laser, etc) effectively manages tumors in the same way. Most of the benefits between the different procedures are for the surgeon or doctor rather than for the patient.
Procedure
During RFA, a thin needle electrode is inserted into the thyroid nodule under ultrasound guidance. Radiofrequency energy is delivered through the electrode, generating heat that destroys the targeted tissue. The procedure typically takes less than an hour and is performed on an outpatient basis, allowing patients to return home the same day.
Benefits and Risks
RFA offers several benefits, including a minimally invasive approach, reduced recovery time, and minimal scarring. It is a suitable option for patients who wish to avoid more invasive surgery. However, potential risks include infection, bleeding, and unintended damage to surrounding tissues. These risks are generally low, and your doctor will discuss them with you to ensure you are fully informed.
Recovery and Follow-Up
Recovery from RFA is typically quick, with most patients able to resume normal activities within a few days. Mild discomfort at the treatment site is common and can be managed with over-the-counter pain medications. Regular follow-up appointments are important to monitor the treated nodule and ensure the procedure's success. Additional treatments may be needed if the nodule does not shrink as expected.
