Should total thyroidectomy become the preferred procedure for surgical management of Graves' disease?
This study aims to evaluate our institution's experience with thyroidectomy for Graves' disease, with an emphasis on indications and long-term outcomes. The study cohort consisted of 103 patients (mean age 34.3 [+/-13.9] years), who underwent thyroidectomy for Graves' disease between 1991 and 2002. Clinical and follow-up data were obtained by retrospective review of medical records and by contacting treating physicians or patients. The most common surgical indications were patient preference (26%), cold nodule (24%), eye symptoms (20%), large goiter size (18%), allergy to antithyroidal medications (15%), and age younger than 16 years (14%). Thyroidectomies performed included 45 (total or near-total), 57 subtotal, and 1 lobectomy. Transient complications included hypocalcemia in 42 patients, and recurrent laryngeal nerve palsy in 5 patients. There was no difference in the frequency of hypocalcemia in patients undergoing total or subtotal resections. One patient developed permanent hypocalcemia and 2 permanent recurrent laryngeal nerve (RLN) injury. Only 3 patients who underwent subtotal resections remain off thyroxine and 2 developed recurrent hyperthyroidism approximately 17 and 54 months after surgery. Subtotal thyroidectomy is associated with a high rate of hypothyroidism and large remnants have potential for recurrence. Total or near-total thyroidectomy obviates these disadvantages and can be performed without increased complication rates, thus appearing to be the preferred extent of thyroidectomy for Graves' disease.
