Thyroid surgery

Summary

Thyroid surgery is a procedure commonly performed to treat benign and malignant thyroid disorders. Total thyroidectomy entails the removal of the entire thyroid gland and is indicated in the management of thyroid cancer or benign thyroid conditions that affect the entire gland (e.g., Graves' disease, multinodular goiter). A small cuff of tissue adjacent to the tracheoesophageal groove is spared in near-total and subtotal thyroidectomy in order to protect the parathyroid glands and the adjacent nerves. Lobectomy (removal of a single lobe) or hemithyroidectomy (removal of a single lobe with the isthmus) is performed for unilateral benign thyroid disorders (e.g., toxic adenoma, recurrent thyroid cysts) and for small, low-risk differentiated thyroid cancers. Postoperative complications include hematoma formation, hypoparathyroidism, nerve palsy (recurrent/superior laryngeal nerve), and hypothyroidism. The greater the extent of resection, the greater the risk of complications. However, the most extensive resections (total thyroidectomy) are associated with the lowest rates of recurrent disease.
