In general, the best time for post-thyroid surgery scar repair is related to the patient’s physical condition, post-operative care, repair method and other factors, premature intervention may instead be detrimental to scar repair, and may also increase the chance of infection. Localized wounds after thyroid surgery usually take about half a month to heal well, and for those with slower healing wounds usually take about 2 months to heal well. It is only at this time that medication can be applied under the professional guidance of a doctor to prevent scarring. Especially for some scarred patients, you can use some creams to soften scars and get rid of scars. If scar hyperplasia occurs, it is recommended that after 1 year, when the hyperplasia is more stable, the hyperplastic scar tissue can be repaired by surgically removing the scar tissue, at this time, it is still necessary to apply medication to the wound to prevent scar hyperplasia. Avoid premature use of medication or surgical repair, so as not to increase the chance of infection, resulting in repeated scar proliferation.
