The nodules were previously biopsied and turned out to be benign colloid nodule. Upon literature search, this procedure is commonly performed in Korea and Europe.
I found out the procedure could be performed in an outpatient setting under local anesthesia. It's usually performed as a staged procedure for safety purposes. It's relatively safe as long the proceduralist is mindful of important structures (i.e. recurrent laryngeal and vagus nerves, contents of the carotid sheaths).
The procedure is performed using continuous low voltage using a moving target approach.
Alternatives to the procedure which are usually performed include conservative management versus hemi- or total thyroidectomy depending on which thyroid lobes are involved.
After a literature search, I found out that the procedure is effective for improving cosmetic outcomes
