Radiofrequency Ablation of Thyroid Nodules: Basic Principles
and Clinical Application

1. Introduction
Thyroid nodules constitute a frequently seen clinical problem,
and the incidence of thyroid nodules has increased with
the recently increased use of thyroid ultrasonography (US)
[1]. Although most thyroid nodules are benign and do not
require treatment, some benign nodules may require treatment
for associated symptoms and/or because of cosmetic
problems [2, 3]. As curative surgery has several drawbacks
[4] and the efficacy of thyroid hormone-suppressive therapy
has not yet been determined [5], nonsurgical, minimally
invasive treatment modalities, such as ethanol ablation
(EA), percutaneous laser ablation, and radiofrequency (RF)
ablation, have been used to treat thyroid nodules. EA is
known to be very effective for treating cystic nodules,
although it is less effective for solid nodules [2, 6]. Laser
ablation has been investigated primarily for the treatment of
solid nodules [7]. Recently high-intensity focused ultrasound
and microwave have been introduced as thermal ablation
methods for the treatment of thyroid nodules [8–10].
Since RF ablation of thyroid nodules was introduced
in 2006, it has been reported to be both safe and effective
for treating benign thyroid nodules and recurrent thyroid
cancer.
