Radiofrequency Ablation (RFA) of Thyroid Nodules in Houston

Thyroid nodules (a small lump or growth on the thyroid gland in your neck), even when benign, can become large enough to cause problems. Noticeable symptoms include difficulty swallowing or breathing, a persistent cough, and hoarseness.

At Texas ENT Specialists in Houston, we offer Radiofrequency Ablation (RFA) as a non-surgical option to shrink the nodules and improve thyroid function. This minimally invasive treatment can alleviate the discomfort associated with thyroid nodules, helping you regain your quality of life and ease any swallowing or breathing issues you may be experiencing.

Interventional Endocrinology: The Future of Minimally Invasive Treatment

Interventional endocrinology is a cutting-edge specialty that addresses various endocrine disorders through minimally invasive, image-guided procedures. This approach employs techniques that avoid the more extensive open surgeries typically required for endocrine-related conditions.

Instead, using delicate needle-like tools, the surgeon is guided by ultrasound to target and eradicate the issue under the skin without using large incisions. Radiofrequency ablation (RFA) can be directly targeted at the problem, effectively treating benign thyroid nodules and, in some cases, lymph nodes affected by recurrent cancer.

What is Radiofrequency Ablation (RFA)?

The RFA procedure is a minimally invasive technique performed by an endocrine surgeon under ultrasound guidance. It utilizes targeted radio waves to disrupt the cells of a thyroid nodule, leading to shrinkage as the body gradually absorbs the ablated tissue. A tiny needle generates precise radio waves that heat and destroy a small area of tissue.

Since its introduction in 2002, radiofrequency ablation (RFA) of thyroid tissue has proven particularly effective for recurrent thyroid cancer and symptomatic benign thyroid nodules. This approach offers a safe and effective alternative for patients who may not be suitable candidates for traditional surgery.

Your Procedure: What to Expect

RFA effectively reduces the size of thyroid nodules by using a safe, alternating electric current that disrupts tissue ions as they follow the current, generating frictional heat around the electrode. This heat specifically targets and destroys the unwanted tissue.
About 30 minutes before the procedure, you will be administered a low-dose sedative to help you feel relaxed and calm. A local anesthetic will also be applied to the treatment area around the thyroid gland to ensure your comfort. Typically, you can expect to go home about 30 to 45 minutes after the procedure. Any discomfort afterward can usually be managed easily with over-the-counter pain relievers.

Aside from avoiding heavy lifting for the day, there are no significant restrictions following the procedure. Patients can generally resume their normal activities on the same day, making RFA a convenient option for treatment.

A Positive Non-Surgical Solution

Unlike traditional surgery, which often involves removing part of the thyroid, RFA preserves the integrity of the gland, helping to maintain its function. This preservation is one of the standout advantages of using radiofrequency ablation for thyroid nodules.

Patients undergoing RFA for benign thyroid nodules typically experience a reduction in nodule size by 50-90% within the first six months to a year. Additionally, many patients report significant improvement or complete resolution of nodule-related symptoms, further highlighting the effectiveness and benefits of RFA at Texas ENT Specialists in Houston.

RFA Benefits for Thyroid Nodules

The benefits of radiofrequency ablation (RFA) for thyroid nodules include:

Enhanced quality of life

Many patients find significant relief from symptoms, improving their overall well-being.

Minimally invasive

The procedure is performed with a small needle, minimizing trauma compared to traditional surgery.

No visible scarring

The small needle entry leaves no noticeable scars.

Outpatient procedure

Under local anesthesia, RFA allows for same-day discharge without hospitalization.

Low complication rate

RFA has a minimal risk of complications while effectively reducing nodule size.

Shorter recovery time

Patients typically recover faster than they would from surgical options, resuming normal activities quickly.

Candidates for RFA for Thyroid Nodules

Patients with benign thyroid nodules who are candidates for surgery are often suitable candidates for radiofrequency ablation (RFA). If you experience symptoms or cosmetic concerns from a growing nodule or if you have a nodule that produces excess thyroid hormone, RFA may be a good option for you. Additionally, individuals unable to undergo surgery due to anesthesia risks or other health concerns should also consider RFA for treating thyroid nodules.

RFA Results

After undergoing radiofrequency ablation (RFA), patients can anticipate a reduction in nodule size of 50% to 90%, with the most significant shrinkage occurring within the first four weeks. The nodule may continue to decrease in size over the next six months to a year, leading to ongoing improvement in symptoms.

Your endocrinologist will closely monitor your recovery through ultrasound examinations, as the likelihood of the nodule regrowing is relatively low. In the rare event that the nodule does reappear, RFA can be repeated, or surgical options can be considered. For those with hormone-producing thyroid nodules, RFA can help normalize blood hormone levels.
