The time to remove the gauze after thyroid surgery is somewhat related to the patient’s wound healing, and usually can be removed about 10 days after surgery. Thyroidectomy surgery usually has a small surgical incision, and with rich blood circulation in the neck, healing is faster, and the gauze can usually be removed about 10 days after surgery. If there is localized swelling, it may need to be delayed, 2 to 3 weeks before it can be removed. During this time, care should be taken to sterilize the wound. Thyroid surgeries include subtotal excision, total excision and so on. In case of subtotal resection, levothyroxine supplementation is needed for a period of time after the operation to meet the metabolic needs of the body. If the whole thyroid gland is removed, levothyroxine needs to be taken for life. Patients are advised to carry out a series of follow-up operations such as disinfection, removal of gauze and suture removal under the guidance of professional physicians, and medications need to be reasonably applied according to the doctor’s instructions.
