After thyroid surgery, silicone patches are usually not applied until the wound has healed, and the exact recovery time should be determined by the trauma of the surgery as well as the individual. Usually one week after surgery, after the stitches are removed. After having thyroid surgery, silicone patches are generally required to be applied only after the wound has healed. The wound usually heals about a week after surgery and the stitches are removed. Using the silicone patch before the wound has recovered is prone to allergic reactions, inflammatory reactions, resulting in redness, swelling and pain. However, the specific recovery time is related to the individual situation and the size of the surgical trauma. The main ingredient of silicone patch is silicone gel, which can be used to repair the skin and lighten the scars. The main mechanism of action is to make the color of congested scars gradually degrade through moisturizing, so that the hyperplastic scars can be restored to flat. If you need to use silicone gel patch after thyroid surgery, you should do it under the guidance of your physician, and for those who have poor results, you can consider going to the hospital for laser treatment.
