Thyroid Nodule Ablation
Thyroid nodule ablation aims to reduce the size of selected benign nodules and relieve associated pressure or cosmetic concerns. Not every thyroid nodule requires treatment. Ultrasound, thyroid function and, where appropriate, biopsy results guide the decision.

Who may be suitable?
Ablation may be considered for nodules confirmed to be benign that cause symptoms or cosmetic concerns. Observation and surgery remain relevant alternatives. Cancer suspicion or abnormal hormone production changes the assessment; benign nodule ablation should not be presented as a routine treatment for thyroid cancer.
Available approaches
Thermal techniques such as radiofrequency ablation use heat under ultrasound guidance to treat the target tissue. Ethanol ablation may be considered for selected recurrent cystic nodules. Thyroid artery embolisation is a separate catheter-based approach requiring its own assessment.
What happens after treatment?
The nodule usually changes in size over time rather than disappearing immediately. Ultrasound and any required hormone tests are used for follow-up. Persistent symptoms or regrowth can lead to further investigation or repeat treatment. Discharge and return to normal activities are planned individually.
Benefits and risks
Ablation targets the nodule while aiming to preserve surrounding thyroid tissue. It avoids a large surgical incision but can still cause pain, bruising or bleeding. Voice changes and injury to nearby structures are risks that must be discussed. Thyroid function is not guaranteed to remain unchanged.
