Dr.Guttler’s Comments.

  1. 126 thyroid nodules treated by RFA were followed for 4 years.
  2. Nodules decreased 93%  from 10 ml to < 1 ml.
  3. Cosmetic scores also improved.
  4. 4 year recurrence rate was 7/126 or 5.7 %
  5. Complication rate was 4/111 or 3.7%.
  6.  no life-threatening complications or sequelae.
  7. Call to see if you are a candidate for my outpatient RFA therapy.

My lecture on thyroid nodule therapy with RFA at AACE meeting in Austin Texas.


No scar or hospital visit with my outpatient therapy for your nodule.



Simple outpatient procedure can rid you of your symptomatic and cosmetic problem.


A patient with a visible nodule with symptoms and an obvious cosmetic issue as well.

Featured image is of a spongiform nodule which is one of the best for RFA therapy.

Radiofrequency ablation of benign non-functioning thyroid nodules: 4-year follow-up results for 111 patients

   Hyun Kyung Lim et al



To evaluate the clinical outcomes and safety of radiofrequency (RF) ablation for benign non-functioning thyroid nodules over a 4-year follow-up.


We evaluated 126 benign non-functioning thyroid nodules of 111 patients treated with RF ablation and followed-up more than 3 years. RF ablation was performed using the Cool-Tip RF system and an internally cooled electrode. Nodule volume and cosmetic and symptom scores were evaluated before treatment and during follow-up. Complications and factors related to efficacy were evaluated.


The mean follow-up duration was 49.4 ± 13.6 months. Thyroid nodule volume decreased significantly, from 9.8 ± 8.5 ml before ablation to 0.9 ± 3.3 ml (P < 0.001) at final evaluation: a mean volume reduction of 93.4 ± 11.7 %. The mean cosmetic (P < 0.001) and symptom scores (P < 0.001) improved significantly. Factors related to efficacy were initial solidity and volume. The overall recurrence rate was 5.6 % (7/126). The overall complication rate was 3.6 % (4/111).


RF ablation was effective in shrinking benign thyroid nodules and in controlling nodule-related problems over a 4-year follow-up. There were no life-threatening complications or sequelae. Therefore, RF ablation can be used as a non-surgical treatment for patients with benign non-functioning thyroid nodules.

Key Points

• Radiofrequency (RF) ablation provides a non-surgical option for benign non-functioning thyroid nodules

• RF ablation reduced non-functioning thyroid nodular volume by 93.5 % after 49 months

• Initial solidity and volume influenced the efficacy of RF ablation

• Larger thyroid nodules required more treatment sessions to achieve appropriate volume reduction

• Complete treatment of the periphery of the nodule is important in preventing marginal regrowth
