The Claim
Total thyroidectomy is associated with a significantly lower rate of recurrent hyperthyroidism compared to subtotal thyroidectomy in patients with Graves' disease, with 0% recurrence in 302 patients undergoing total thyroidectomy and 8% recurrence in 125 patients undergoing subtotal thyroidectomy.
What the research says
Supports is higher
Support is ahead, but a single strong opposing study can change this.
These are independent scores, not a percentage. Higher-grade studies count more, so a single strong opposing study can outweigh several weaker ones.
Patients with Graves' disease who undergo complete removal of the thyroid gland have no recurrence of hyperthyroidism, while 8% of those who undergo partial removal experience recurrence.
See the scientific wording
Total thyroidectomy is associated with a significantly lower rate of recurrent hyperthyroidism compared to subtotal thyroidectomy in patients with Graves' disease, with no recurrences observed in 302 patients undergoing total thyroidectomy versus 8% recurrence in 125 patients undergoing subtotal thyroidectomy, suggesting that complete removal of thyroid tissue reduces the likelihood of disease return despite higher rates of transient hypoparathyroidism.
When part of the thyroid is left behind, the remaining tissue continues to make too much thyroid hormone because antibodies keep stimulating it. This causes the disease to come back. Removing all thyroid tissue stops this process completely.
What the research says
1 studyRemoving the whole thyroid gland stops Graves' disease from coming back much better than leaving some behind—even though some people temporarily have low calcium after full removal. The study shows no one had the disease return after full removal, but 8% did after partial removal.
