Both removing the entire thyroid and leaving a small 3-gram piece can permanently stop Graves' disease from coming back, with no recurrences seen in either group over nearly four years of follow-up.
Claim Context
Total thyroidectomy in patients with Graves' disease is associated with zero disease recurrence over a mean follow-up of 47 months, while subtotal thyroidectomy with a 3 g remnant also shows no recurrence, suggesting both procedures effectively eliminate hyperthyroidism when performed with adequate tissue removal.
“The patients who underwent TT had no recurrence during a mean follow-up of 47 months. After STT, with the mean weight of the thyroid remnant 3.0±1.0 g, there was no relapse of Graves' disease during a mean follow-up of 52 months.”

What Would Prove This
Per GRADE and EBM methodology, here is what ideal scientific evidence would look like to definitively prove or disprove this claim, ordered from strongest to weakest.
Whether total and subtotal thyroidectomy have equivalent long-term recurrence rates in Graves' disease across diverse surgical practices and patient populations.
A systematic review and meta-analysis of all randomized controlled trials comparing total versus subtotal thyroidectomy in Graves' disease, with recurrence as the primary endpoint at 5 and 10 years, stratified by remnant size and surgeon volume.
Whether total thyroidectomy and subtotal thyroidectomy with a 3 g remnant have equivalent rates of Graves' disease recurrence over 10 years.
A multicenter, double-blind, randomized controlled trial of 400 adults with Graves' disease, randomized to total thyroidectomy versus subtotal thyroidectomy with intraoperative remnant mass targeted at 3 g (±0.5 g), with recurrence defined as TSH <0.1 mIU/L and positive TSH receptor antibodies at 12, 36, and 120 months.
Whether recurrence rates are similar between total and subtotal thyroidectomy in a large, prospectively followed cohort with standardized follow-up.
A prospective cohort study of 600 patients undergoing either total or subtotal thyroidectomy for Graves' disease, with standardized surgical technique, remnant measurement, and annual thyroid function and antibody testing for 10 years.
Whether patients who experience recurrence after subtotal thyroidectomy differ in remnant characteristics from those who do not.
A case-control study comparing 50 patients with recurrent Graves' disease after subtotal thyroidectomy to 150 matched controls without recurrence, analyzing remnant weight, proportion, histology, and preoperative antibody levels.
The prevalence of recurrence in patients who underwent either total or subtotal thyroidectomy at a single time point.
A cross-sectional survey of 300 patients who underwent thyroidectomy for Graves' disease at least 5 years prior, measuring current TSH, TSH receptor antibodies, and ultrasound-confirmed remnant presence.
