Summary
Radiofrequency (RF) ablation effectively treats multinodular goiter, significantly improving symptoms and cosmetic appearance. This repeatable procedure offers a non-surgical option, preventing regrowth in selected patients.
Area of Science:
- Endocrinology
- Minimally Invasive Surgery
Background:
- Multinodular goiter often requires treatment for cosmetic concerns and symptoms.
- Radiofrequency (RF) ablation presents a minimally invasive therapeutic option.
Purpose of the Study:
- To evaluate the efficacy of RF ablation for cosmetic and symptom relief in patients with extensive multinodular goiter.
Main Methods:
- Retrospective analysis of 40 patients with 175 nodules treated with monopolar RF ablation.
- Assessment included clinical symptoms, lab tests, and ultrasound monitoring.
Main Results:
- Significant symptom improvement (2.9 to 0.3) and cosmetic score reduction (3.6 to 1.6) were observed (P < .001).
- Mean nodule volume reduction was 85.3%.
- Most patients required one ablation session; temporary hoarseness occurred in 7.5%.
Conclusions:
- RF ablation is a safe and effective, repeatable treatment for multinodular goiter.
- It provides substantial symptom and cosmetic improvement.
- It can prevent nodule regrowth and avoid surgery in selected cases.
