Thyroid Radiofrequency Ablation
A Non-Surgical Treatment of Thyroid Nodules
What is Thyroid Radiofrequency Ablation or RFA?
Thyroid Radiofrequency Ablation (RFA) is a safe and minimally invasive outpatient procedure designed to treat benign thyroid nodules without the need for surgery. Since it is performed on an outpatient basis, there is no need for hospital admission, allowing patients to return home the same day. The procedure itself is quick, typically lasting only 20-30 minutes, and involves the use of radiofrequency energy to reduce the size of thyroid nodules while preserving normal thyroid function.
Are You a Candidate for RFA?
If you have a benign thyroid nodule causing symptoms — trouble swallowing, a persistent cough, a feeling of fullness in the neck, or visible swelling — RFA may be an option. Nearly all benign nodules we treat shrink significantly. The simplest way to find out if you qualify is a quick phone call.

What is Thyroid RadioFrequency Ablation (RFA) for Thyroid Nodules?
How effective is Thyroid RadioFrequency Ablation (RFA) in treating thyroid nodules?
When is Thyroid RadioFrequency Ablation (RFA) indicated?
- Causing compressive symptoms such as difficulty swallowing or breathing, constant cough, persistent voice changes, and sensation of a lump in the throat.
- Cosmetically unappealing because of size.
Thyroid RadioFrequency Ablation (RFA) is also indicated for toxic or overactive nodules that are causing hyperthyroidism, and in patients who are not surgical candidates or who would prefer to avoid surgery.
How can a patient be evaluated for treatment with Thyroid RadioFrequency Ablation (RFA)?
Candidates for Thyroid RadioFrequency Ablation (RFA) must complete:
- Two FNA biopsies taken on 2 different occasions, and showing benign results
- One FNA biopsy of a toxic or overactive nodule showing benign results
Soon, we anticipate that patients with indeterminate biopsy results will qualify for Thyroid RadioFrequency Ablation (RFA) if Thyroseq genetic testing results are negative.
Why choose Thyroid RadioFrequency Ablation (RFA) over surgical removal of the thyroid?
- Treats problematic nodules while leaving healthy thyroid tissue intact.
- Significantly less invasive and does not leave a scar.
- Performed with local anesthesia, with minimal to no discomfort.
- Has a recovery time of 15-30 min and does not require a hospital stay.
- Has an extremely low risk of complications.
Are there any risks or side effects associated with Thyroid RadioFrequency Ablation (RFA)?
Thyroid RadioFrequency Ablation (RFA) is a safe procedure with minimal risks. In a large study of more than 1500 patients, the following possible complications were noted:
- Temporary voice changes in 1% of patients, with no permanent voice changes.
- Hematoma in 1% of patients, resolved within 1 week.
- Vomiting in 0.6% of patients, resolved in 1-2 days.
- Mild skin burn in 0.3% of patients, resolved in 1 week.
- Nodule rupture in 0.14% of patients, treated conservatively
- Infection involving the thyroid nodule in 0.07% treated with antibiotics
