Most thyroid nodules are benign, but careful evaluation is essential to determine which require treatment. Using structured ultrasound assessment and, when necessary, a biopsy, we can identify nodules that may be suitable for minimally invasive options like radiofrequency ablation (RFA). For selected patients, RFA can shrink the nodule and relieve symptoms while preserving the thyroid gland helping them avoid thyroidectomy, visible scarring, and the potential need for lifelong thyroid hormone replacement
Why Many Patients Want to Avoid Thyroid Surgery
Thyroid nodules are a type of growth that develops within the thyroid gland that affects up to 65% of healthy adults. While the vast majority of thyroid nodules are benign and 10-15% can be cancerous, even benign nodules can grow large and cause symptoms such as pain and difficulty swallowing. Unfortunately, many people with thyroid nodules choose to live with these symptoms, as, traditionally, the only treatment option was to undergo a partial or total thyroidectomy. Because most thyroid nodules are not life-threatening, many patients choose to live with them rather than undergo surgery.
This is because even though thyroid surgery is a safe, common procedure, it can cause significant scarring, and it may require patients to take thyroid hormone replacement medications for the rest of their lives. The good news is that there is now an alternative, minimally invasive treatment option for thyroid nodules called radiofrequency ablation (RFA). With RFA, doctors can now shrink certain thyroid nodules without the need for surgery, providing Singapore residents with symptom relief without the need for lifelong medication. Keep reading to learn more about RFA for thyroid nodules and how you’ll know if it’s right for you.
Common Questions About Radiofrequency Ablation (RFA) for Thyroid Nodules
What is radiofrequency ablation (RFA) for thyroid nodules?
Radiofrequency ablation (RFA) is a minimally invasive treatment that uses heat generated by a specialised needle to reduce the size of selected benign thyroid nodules. The procedure is performed under image guidance with the aim of relieving symptoms while preserving normal thyroid tissue.
Who is suitable for thyroid RFA?
RFA may be considered for patients with benign thyroid nodules that are causing symptoms such as neck discomfort, swallowing difficulties or cosmetic concerns. Suitability depends on factors including ultrasound findings, biopsy results, the size and location of the nodule, and your overall health.
Can RFA help me avoid thyroid surgery?
For suitable patients with benign thyroid nodules, RFA may provide an effective alternative to surgery. However, not every thyroid nodule is appropriate for RFA, and some patients may still benefit from surgical treatment. A vascular specialist assessment is needed to determine the most suitable option.
How is thyroid RFA different from thyroid surgery?
Unlike thyroid surgery, RFA is performed through a small needle under ultrasound guidance and does not require a surgical incision. For suitable patients, this minimally invasive approach may offer a shorter recovery period while preserving the thyroid gland.
What happens after thyroid RFA?
Most patients can return to normal daily activities relatively quickly following the procedure. Follow-up appointments and repeat ultrasound examinations are used to monitor how the treated thyroid nodule responds over time.
What Are Thyroid Nodules?
Thyroid nodules are solid or fluid-filled growths that form within the butterfly-shaped gland in the neck called the thyroid. While these nodules are extremely common, the vast majority are benign (noncancerous), and they typically do not cause symptoms. In fact, many people do not realize they even have them until they are discovered in routine physicals or when undergoing scans for something else. However, in some instances, benign thyroid nodules can grow and cause difficulty breathing, speaking, and swallowing. While many thyroid nodules will never require treatment, large, symptomatic nodules may need to be treated, with surgery and RFA being the most common treatment options.
What is Thyroid RFA?
So, what exactly is radiofrequency ablation for thyroid nodules? RFA is a minimally invasive treatment option that can help some people with thyroid nodules avoid surgery. During this procedure, a small needle electrode is inserted into the thyroid nodule using ultrasound guidance. Heat is then generated at the needle tip, which destroys the nodular tissue. This causes the nodule to shrink in the weeks following the procedure, providing symptom relief while preserving thyroid function.
Who May Be a Candidate for Thyroid RFA?
RFA is typically appropriate for patients with benign thyroid nodules that cause symptoms or cosmetic concerns. Typically, two biopsies with benign results are required for RFA to be chosen, as suspicious or cancerous nodules are not suitable for RFA treatment. Whether or not you may be a candidate for thyroid RFA depends on:
- The Type of Thyroid Nodule: Thyroid nodules must be confirmed to be benign to be treated by RFA. Additionally, only solid thyroid nodules can be treated, as RFA is not effective on fluid-filled (cystic) nodules.
- Your Symptoms and Impact on Daily Life: Symptomatic nodules that cause difficulty breathing and swallowing, or that cause cosmetic concerns, may be a candidate for RFA.
- Nodule Size and Growth: Thyroid nodules that are actively growing and/or are not responding to medication may be treated with RFA.
When Thyroid RFA May Not Be Suitable
While RFA is a highly effective treatment for benign thyroid nodules, not everyone qualifies for this procedure. You may not be a suitable candidate for thyroid RFA if:
- Thyroid cancer is suspected
- Your nodule is small/asymptomatic
- You have aggressive or complex thyroid nodules
- Your thyroid nodules are close to critical structures, such as major blood vessels
- Or you have a pacemaker
Ultimately, it’s important that you talk to a specialist who can assess your overall health and help you determine if RFA is the best course of action for treating your thyroid nodules.
Thyroid RFA vs Thyroidectomy: Key Differences
You may find yourself wondering what the primary differences are between thyroid RFA and thyroidectomy. Ultimately, the main differences between the two come down to their invasiveness and complexity. Thyroidectomy is an invasive surgery in which part, or all, of the thyroid is removed. This can cause significant scarring, require a hospital stay and lengthy recovery time, and you may require permanent thyroid hormone replacement. Alternatively, thyroid RFA is a minimally invasive procedure that can be performed in an outpatient setting, requires minimal recovery time, and does not result in scarring or the need for hormone replacement.
Is Thyroid RFA Available in Singapore?
RFA for the treatment of thyroid nodules is an option for patients in Singapore. However, to ensure the success of your procedure, it’s essential that you take the time to find an experienced doctor. Ideally, you should choose a clinic that not only has thyroid RFA expertise but also offers multidisciplinary care, including endocrinology and interventional expertise, as this will ensure you receive the highest quality of care.
Thyroid Nodules RFA Frequently Asked Questions
1. Is RFA Painful?
RFA is a minimally invasive, outpatient treatment option that typically does not cause pain, as a local anesthetic is used to numb the area.
2. Can RFA Completely Remove My Thyroid Nodule?
While your thyroid nodule may not completely disappear, RFA typically causes nodules to shrink by 50-90%, providing significant symptom relief.
3. Will My Thyroid Function Change?
Because RFA only destroys the nodule while preserving healthy thyroid tissue, thyroid function is typically unaffected by this procedure.
4.Will RFA Cause Scarring?
No, thyroid RFA does not require an incision and will not result in scarring.
When to Consider a Vascular Specialist Assessment
Many thyroid nodules do not require treatment, but some may continue to grow or cause symptoms that affect daily life. A specialist assessment helps determine whether radiofrequency ablation (RFA), ongoing monitoring or surgery is the most appropriate management option.
Consider seeking a specialist assessment if you:
- Have a benign thyroid nodule confirmed by ultrasound and, where appropriate, biopsy
- Notice your thyroid nodule is increasing in size
- Experience neck pressure, discomfort, difficulty swallowing or cosmetic concerns related to a thyroid nodule
- Have been advised to undergo thyroid surgery and would like to understand whether RFA may be a suitable alternative
- Would like a second opinion regarding treatment options for a benign thyroid nodule
A specialist consultation includes reviewing your symptoms, thyroid ultrasound findings, biopsy results and medical history to determine whether radiofrequency ablation is an appropriate treatment option for your individual condition.
