Surgical Intervention

  • Surgery is not the1st-line treatment; pharmacotherapy is usually preferred over surgery
  • Near-total or total thyroidectomy is the preferred surgery
  • Effects: Up to 98% success rate when performed by experienced surgeons
  • May be option for:
    • Suspected thyroid cancer (excision of thyroid nodules to rule out malignancy)
    • Patients who want unsightly goiter removed
    • Patients who refuse radioactive iodine & want definitive treatment
    • Pregnant patients who are intolerant of antithyroid agents
    • Some physicians prefer surgery in pediatric/adolescent patients, esp if large goiter
  • Potential complications: Hypoparathyroidism, laryngeal edema, hemorrhage & nerve damage
Prior to Surgery
  • Restoration of euthyroidism to decrease risk of thyrotoxic storm
    • Antithyroid drug treatment prior to surgery, w/ or w/o inorganic iodide given x 7-10 days prior to surgery to block thyroid hormone synthesis
    • Inorganic iodide given x 7-10 days prior to surgery to block thyroid hormone synthesis (controversial)
