When the entire thyroid gland is removed in children with Graves' disease, the chance of the condition returning is much lower than when only part of the gland is removed.

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.
A systematic review of RCTs comparing total versus subtotal thyroidectomy would definitively determine whether complete removal causally reduces recurrence risk by eliminating surgical selection bias.
A systematic review and meta-analysis of all randomized controlled trials comparing total thyroidectomy versus subtotal thyroidectomy in children aged 8–18 with Graves' disease, with recurrence defined as TSH <0.1 mIU/L and free T4 >1.8 ng/dL without medication at 5 years, and outcomes assessed by blinded endocrinologists.
A randomized controlled trial would determine whether total thyroidectomy causally reduces recurrence compared to subtotal thyroidectomy by eliminating surgeon preference and patient selection bias.
A multicenter, double-blind RCT enrolling 250 children aged 8–18 with Graves' disease requiring surgery, randomized 1:1 to total or subtotal thyroidectomy, with primary outcome: recurrence of hyperthyroidism at 5 years defined by biochemical criteria, secondary outcomes: hypoparathyroidism, vocal cord function, and quality of life, assessed by blinded endocrinologists and surgeons.
A prospective cohort study with standardized surgical criteria could strengthen the observed association by reducing selection bias in surgical technique choice.
A prospective multicenter cohort study following 400 children aged 8–18 with Graves' disease undergoing thyroidectomy, prospectively assigned to total or subtotal resection based on standardized intraoperative criteria (e.g., gland size, vascularity), with blinded assessment of recurrence, hypoparathyroidism, and nerve injury at 1, 3, and 5 years.
A case-control study could identify whether children who experienced recurrence after subtotal thyroidectomy differed systematically from those who did not, in terms of residual tissue volume or surgical technique.
A matched case-control study comparing 150 children with recurrent hyperthyroidism after subtotal thyroidectomy with 150 matched controls without recurrence, matched for age, preoperative TSH, and gland size, assessing residual thyroid tissue volume on postoperative ultrasound and surgical technique details.
A cross-sectional study could estimate the prevalence of recurrence at a single time point across surgical types, but cannot determine causality or progression.
A national cross-sectional survey of 800 children aged 8–18 with a history of thyroidectomy for Graves' disease, assessing current thyroid status and recurrence at a single time point, stratified by surgical type (total vs subtotal) and time since surgery.
