In a multi-center study of 1459 patients organized by the Korean Society of Thyroid Radiology, the overall complication rate following radiofrequency ablation was 3.3%. The major complication rate was 1.4%. While uncommon, complications can be:
• Temporary voice changes, such as hoarseness.
• Slight bleeding — usually disappears on its own within one day, or at the most, up to three months.
• Wound infections
• In rare cases, vomiting, coughing, or seared skin at the treatment site may occur
• Patients with AFTN (“hot” thyroid nodules) have the possibility of hypothyroidism after the procedure. Although rare, a complication may require an inpatient hospital stay or follow-up treatment.
