What Is Radiofrequency Ablation (RFA)?
Radiofrequency Ablation (RFA) is a minimally invasive, image-guided procedure used to treat certain thyroid nodules without surgery. During the procedure, a thin probe is inserted into the thyroid nodule under ultrasound guidance. Radiofrequency energy is then applied to generate controlled heat, which destroys targeted nodule tissue over time. The treated nodule gradually shrinks, reducing symptoms and cosmetic concerns.
For many patients, RFA provides effective symptom relief while maintaining quality of life. RFA is typically performed on an outpatient basis using local anesthesia, allowing most patients to return to normal activities within one to two days.
At Fox Valley Surgical, our Fellowship trained endocrinologists and endocrine surgeons offer RFA as part of a comprehensive, patient-centered approach to thyroid care—providing advanced treatment options with less downtime and no surgical incision.


Conditions RFA Can Treat
- Benign thyroid nodules that cause symptoms such as:
- Neck pressure or discomfort
- Difficulty swallowing
- Voice changes
- Visible neck swelling or cosmetic concerns
- Autonomously functioning thyroid nodules (hot nodules) that contribute to hyperthyroidism in select cases
- Patients seeking alternatives to surgery who wish to avoid:
- General anesthesia
- Surgical scars
- Thyroid hormone replacement when possible
RFA vs Traditional Surgery
- Minimally invasive – no surgical incision
- Outpatient procedure with shorter recovery time
- Preserves thyroid function in most patients
- No visible scarring
- Lower risk of complications compared to surgery
- Significant reduction in nodule size and symptoms over time
