The wound after thyroid surgery is usually a line that does not protrude from the skin. However, it is also related to the recovery, if the recovery is not good, it may protrude on the surface of the skin as follows: Thyroid surgery is usually performed with a horizontal incision, so the wound is only a line after surgery. If the wound heals well, you will see a horizontal and slightly reddish surgical scar on your neck one month after the surgery, which is not painful to press and will not be hard. However, if the wound does not heal well or the patient has a scarred body, the scar may protrude from the skin and be painful and hard when pressed. In addition, individual patients may also experience redness, swelling and pain in the wound, requiring immediate medical attention.
