Common sequelae of thyroid nodule surgery include hypothyroidism, laryngeal reentry nerve damage, and parathyroid gland damage. Each person’s surgical result is different, and the possible sequelae are also different. 1. Hypothyroidism: The surgery results in the removal of too much normal thyroid tissue, causing hypothyroidism, which requires replacement therapy with levothyroxine sodium to keep the thyroid hormone level within the normal range, and regular checkups. 2. Laryngeal recurrent nerve injury: the laryngeal recurrent nerve is pulled or cut off during the operation, resulting in temporary or permanent damage, which can be manifested as hoarseness, dyspnea and so on. 3. Parathyroid gland injury: the parathyroid gland is adjacent to the thyroid gland, if the injury can lead to a decrease in the secretion of parathyroid hormone, causing hypocalcemia. Thyroid nodule surgery is recommended to be performed in regular hospitals.
