    The study analyzed 411 low-risk papillary thyroid microcarcinoma patients who underwent unilateral lobectomy.

    Spontaneous TSH normalization rates were 32.4% at 0.5 months, declining to 12.4% at 12 months postoperatively.

  • 3

    Younger patients with higher preoperative fT3 and lower preoperative TSH were more likely to achieve spontaneous normalization.

  • 4

    Preoperative TSH ≤ 1.7 μIU/mL was identified as an independent predictor for TSH normalization at 12 months.

    The findings suggest that individualized management may allow deferral of levothyroxine supplementation in eligible patients.
