When RFA Surgery Is Recommended: Your Guide to Minimally Invasive Thyroid Nodule Treatment

Even when benign, thyroid nodules can grow visibly large, causing cosmetic concerns as well as issues with swallowing, breathing, and speaking. While treatment of these nodules once required surgery, Radiogrequency Ablation (RFA) has gained traction as a popular, minimally invasive alternative. With RFA, doctors can use radio waves to create heat that shrinks the size of thyroid nodules without the need for surgery, making it an increasingly popular treatment option in Singapore and on a global scale. Yet, how will you know if RFA is right for you and what you should expect of this procedure? In this article, we explore this minimally invasive thyroid nodule treatment option.

What is RFA?

Radiofrequency Ablation (RFA) is a non-surgical procedure that uses heat generated by radiofrequency energy to shrink thyroid nodules. It is performed under local anesthesia in a clinic or day surgery setting, and it is considered minimally invasive as there are no large incisions or stitches. RFA is then often considered the preferred first-line treatment for benign, non-concerous nodules, as it is safe, effective, and requires minimal recovery time.

When is RFA Recommended?

RFA is generally recommended for the treatment of benign thyroid nodules confirmed by Fine Needle Aspiration (FNA) or core biopsy. Radiofrequency Ablation can be a good alternative to surgery in these cases as it can help reduce symptoms like visible swelling, difficulty swallowing, and voice changes without the need for invasive surgery. This procedure can shrink the nodule while still preserving thyroid function, which is a preferable option for many patients as they can avoid taking lifelong medication. Importantly, you will need to talk to a doctor to see if you are a candidate for thyroid nodule RFA.

Pre-RFA Evaluation and Preparation

Before undergoing RFA on a thyroid nodule, you will first need to have a consultation with a thyroid or interventional specialist to determine if you are a candidate for this procedure. They will use diagnostic testing including a thyroid ultrasound, biopsy, and blood tests to determine the size and location of the nodule and confirm that it is benign and eligible to be treated with RFA. Once these tests are completed, your doctor will review your treatment options, explain the risks, benefits, and outcomes of RFA, and schedule your procedure if you decide this is the right option for you. They will also provide you with pre-procedure instructions regarding fasting, medications, and what to wear on the day of the procedure.

What Happens During The RFA Procedure

During RFA, a small needle electrode is inserted into the thyroid nodules using ultrasound guidance to precisely locate and target the nodule. Heat is then generated at the needle tip using radio waves, which destroys the target tissue. This procedure is performed in an outpatient setting under local anesthesia and is relatively quick, generally lasting 45 minutes to an hour depending on the size of the nodule being treated. Patients are then monitored briefly before going home the same day.

What to Expect After RFA

Patients can leave the clinic the same day with only a small bandage covering the incision point. While RFA is popular due to its efficacy and low instance of complications, patients may experience minor discomfort, swelling, and bruising following this procedure; however, this can be easily treated with over-the-counter pain medications.

Most patients should be able to return to their normal activities within 24-48 hours, but it is important that you follow your doctor's aftercare instructions. Patients should expect to see the size of the nodule decrease significantly in the weeks following the procedure, with nodules shrinking up to 80% following one RFA treatment. However, large nodules may require additional treatments to achieve optimal size reduction.

After undergoing RFA, you will be expected to attend follow-up appointments and ultrasound scans to monitor shrinkage and progress, which may take weeks to months. Since only a small incision is made, you will not need stitches, and no scarring will occur.

The Benefits of RFA Compared to Surgery

If you are presented with the option of either undergoing surgery or RFA, you may wonder which is the best option. The fact is that there are numerous benefits RFA provides compared to surgery, including:

• Reduced Complications
• Faster Recovery
• No Scarring
• Preservation of Thyroid Function
• It's a Quick Outpatient Procedure
• There's No General Anesthesia
• RFA is Suitable for Repeat Treatments if Necessary.

Is RFA Right for You?

So, how will you know if RFA is right for you? Considering RFA is a fast, effective, and safe procedure that can help significantly improve the appearance of thyroid nodules, you should consider choosing this treatment option instead of surgery if you have a benign thyroid nodule. However, you may need alternative treatment if your nodule turns out to be malignant (cancerous). We invite you to consult with our thyroid nodules specialist familiar with thyroid nodules and RFA, Dr. Manish Taneja, as he will be able to help you choose the best personalized treatment option.

If you have a benign thyroid nodule that is a cosmetic concern or interferes with speaking or breathing, RFA is a safe, effective option that can help significantly improve your quality of life.

Caring For Your Thyroid Health

Have you ever experienced difficulty swallowing or breathing? You may have risk factors including a family history of thyroid nodules or iodine deficiency. Thyroid nodules are abnormal lumps (growths) within the thyroid gland, a butterfly-shaped gland located below your voice box. Even if most thyroid nodules are benign, 10-15% of nodules are cancerous. Sometimes overgrowth of normal thyroid tissue can lead to hyperthyroidism. In other cases, multiple nodules can form in the thyroid called multinodular goiter. Fluid filled thyroid cysts can be one type of thyroid nodule within the thyroid. More complex nodules may lead to thyroid cancers. Depending on the root cause and type of nodule you have, patients can monitor with regular ultrasound or even have a thyroid fine needle aspiration biopsy (FNAC) if required. Surgery to remove partial or whole thyroid gland can be done but thanks to minimally invasive treatments such as Radiofrequency Ablation (RFA), this procedure can treat noncancerous and cancerous thyroid lumps.
