A Non-Surgical Option for Benign Thyroid Nodules: Radiofrequency Ablation (Thyroid RFA)

If you’ve been told you have a benign thyroid nodule, you may be wondering whether it needs to be removed or if surgery is your only option. For patients across the Midlands of South Carolina and beyond, Thyroid RFA offers a minimally invasive, non-surgical option to help shrink benign thyroid nodules while preserving functional thyroid tissue.

Most thyroid nodules are benign, meaning they are not cancerous. Still, some nodules need to be checked, watched, or treated, especially if they grow or begin causing symptoms.

What Is Radiofrequency Ablation (Thyroid RFA)?

Radiofrequency ablation is a minimally invasive treatment used to shrink benign thyroid nodules.

During radiofrequency ablation of the thyroid nodule, your physician will use ultrasound guidance to place a thin, needle-like device into the thyroid nodule. The device sends controlled heat into the nodule tissue. Following the procedure, the treated nodule tissue will shrink with time.

Shrinking thyroid nodules without surgery is a desirable option for many patients who want relief without a neck incision, visible scar, or removal of functional thyroid tissue. RFA may be an option for some patients, but it is not right for every thyroid nodule.

Before RFA is considered, the nodule should be biopsied. Dr. Thomas is happy to evaluate and biopsy nodules to determine candidacy for RFA. This may include a physical exam, thyroid ultrasound, a biopsy of the nodule, blood work, and other tests.

Who May Be a Candidate for Thyroid RFA?

A good candidate for thyroid RFA is someone with a benign thyroid nodule that is causing symptoms or cosmetic concerns.

You may be a candidate if you have:

Not every nodule needs treatment. Some small nodules can be monitored over time with ultrasound. Others may need surgery, especially if the biopsy is suspicious for malignancy.

When to Worry About Thyroid Nodules

You should talk with a provider if you notice:

• A lump or swelling in the lower front of the neck

• Trouble swallowing

• Trouble breathing, especially when lying down

• Hoarseness or voice changes that do not improve

• Neck pressure or discomfort

• A neck lump that is growing quickly

• Symptoms such as a fast heartbeat, sweating, tremor, or unexplained weight loss

One possible sign of thyroid nodule growth is feeling pressure in the throat or seeing swelling at the base of the neck. However, many thyroid nodules cause no symptoms and are found during an exam or imaging test for another reason.

The cause of nodules in thyroid tissue is not always clear. Nodules may be related to overgrowth of thyroid tissue, fluid-filled cysts, inflammation, or other thyroid changes. Your provider can help determine what type of nodule you have and whether it needs treatment.

What Happens During the Procedure?

Thyroid RFA is typically performed in an office setting using local anesthesia. That means the treatment area is numbed, but you are not put to sleep with general anesthesia.

Here is what patients can usually expect:

1. Provider check-in: Your provider may do a quick exam, answer any last questions, and walk you through what to expect.
2. Local numbing medicine: The neck area is numbed to help keep you comfortable.
3. Ultrasound guidance: Ultrasound helps the provider see the thyroid nodule and guide the treatment.
4. Targeted heat treatment: A thin probe is placed into the nodule. Controlled heat is delivered to the nodule tissue.
5. Follow-up care: The nodule is checked over time to see how it responds.

Benefits of Thyroid RFA vs. Surgery

There are several thyroid nodule treatments, and the best choice depends on the type of nodule, biopsy results, symptoms, thyroid function, and patient goals.

For patients comparing thyroid nodule removal surgery with RFA, the main difference is that surgery removes thyroid tissue, while RFA targets the nodule itself.

Surgery may still be the safest choice if cancer is suspected or confirmed. At South Carolina ENT, patients can discuss both non-surgical and surgical options through Head & Neck services with Dr. Thomas. When surgery is needed, care may also involve the Ambulatory Surgical Center.

"For many patients, radiofrequency ablation may significantly reduce the size of a benign thyroid nodule and relieve symptoms without surgery, scarring, or downtime. Bringing access to this innovative treatment to South Carolina and the Midlands means patients can receive high-quality, minimally invasive care right here in their community."

South Carolina ENT Expertise in Thyroid Care

South Carolina ENT provides care for thyroid nodules and other head and neck conditions throughout Columbia and the Midlands.

Dr. Walsh Thomas is a board-certified otolaryngology head and neck surgeon with training in complex head and neck care. He is also one of the first providers in South Carolina to offer radiofrequency ablation as a non-surgical technique to manage and shrink non-cancerous thyroid nodules.

South Carolina ENT also offers full head and neck services in Columbia and the Midlands.

That expertise matters because thyroid nodules need careful evaluation before treatment. The goal is not just to shrink a lump or remove the thyroid. The goal is to understand what the nodule is, whether it is safest to monitor or treat, and which thyroid nodule treatment fits the patient’s needs.

Patients can also find care at South Carolina ENT locations across the Midlands.

When to Talk to a Specialist

You do not need to panic if you think you have a thyroid nodule, but you should not ignore it either.
