Thyroid nodules: when is surgery the answer?
Article image
Not every nodule needs an operation. The assessment criteria and the treatment options, discussed.
How do we assess a nodule?
- History and examination (size, lymph nodes, hoarseness)
- Ultrasound features (margins, calcifications, suspicious pattern)
- Thyroid function tests when indicated
- Fine-needle aspiration (FNA) for nodules that meet criteria
When is surgery more likely?
- Biopsy suggesting malignancy or suspicion
- Large nodule causing pressure symptoms (swallowing or breathing difficulty)
- Overactive nodule not suitable for, or not responding to, medical therapy
- Rapid growth or worrisome changes on follow-up
What operation is performed?
Surgery may be a lobectomy (one lobe) or total thyroidectomy. The choice depends on biopsy findings and whether disease affects one or both lobes. Risks and benefits of each option are discussed with the patient.
Risks to understand
- Temporary, and rarely permanent, voice change (recurrent laryngeal nerve)
- Temporary low calcium after total thyroidectomy (parathyroid glands)
- Bleeding or a neck hematoma needing close observation
The key question is not only “operate or not”, but also: what tests are needed, and is a lobectomy enough or is total removal required?
