The Use of Radiofrequency Ablation for Benign Thyroid Nodules

Abstract

Abstract

Introduction:

Traditionally, thyroidectomy has been the standard of care in treatment of symptomatic benign thyroid nodules. For the past 20 years, thermal ablative techniques have gained global popularity in the management of benign thyroid nodules with radiofrequency ablation (RFA) as the most widely adopted technique. In this video, we summarize considerations and techniques associated with RFA of a large complex benign nodule.^1–17

Materials and Methods:

Before RFA, thyroid nodules are characterized using ultrasound and require two biopsies to confirm benign cytology. In this video, we demonstrate the fundamental techniques that enable RFA to be performed safely for thyroid nodules.

Results:

RFA allows for effective volume reduction of benign thyroid nodules, as evidenced in postprocedure ultrasound follow-up scans. The reduction size is measured in terms of volume reduction ratio, which is calculated as ([initial volume−final volume] × 100)/initial volume.

Conclusions:

RFA is a safe and effective treatment option for benign thyroid nodules. The trans-isthmic and moving shot techniques as well as hydrodissection and vascular ablation techniques are methods to reduce RFA complications and optimize outcomes, respectively.
