— Explanation · 中文詳解 —
甲狀腺切除手術中可能誤傷副甲狀腺，導致副甲狀腺素下降，進而引發低血鈣。指尖與唇周刺痛（Trousseau's 或 Chvostek's 徵象前兆）是低血鈣的神經肌肉興奮症狀，需立即報告並監測以防喉部痙攣。
Tingling in the fingers and perioral area suggests hypocalcemia, a common complication following thyroidectomy due to accidental removal or damage to the parathyroid glands. This neuromuscular irritability requires immediate assessment and intervention to prevent progression to laryngospasm or tetany.
