How long it takes for the wound to heal after thyroid surgery is usually related to the way of thyroid surgery and the basic condition of the patient, and the wound usually heals basically in 3~5 days. When hyperthyroidism, simple goiter and thyroid nodule are removed, usually only a small portion of the diseased thyroid tissue is removed, with less tissue destruction, and generally there is no need to place a drain after surgery, usually the wound is basically healed in 3~5 days after surgery. If the patient is combined with diabetes, hypertension and other systemic diseases, the recovery time will be relatively slower, because of its own vascular lesions, the blood supply of the wound is poorer, the recovery time will be slower than normal. Post-thyroid surgery patients should follow the doctor’s instructions for regular follow-up, continue observation and treatment under the doctor’s guidance.
