Scars from thyroid surgery generally fade over time, and there are certainly treatments available to promote softening and flattening of the scar. After thyroid surgery, localized scarring also goes through a period of formation, hyperplasia, and then enters a stage of maturation, fading, and atrophy. Generally, the scar is in the proliferative stage for 3-6 months or even 9 months after surgery. The localization can be obviously elevated, the texture is relatively hard, sometimes there is obvious itching discomfort, usually symptomatic treatment can be. Symptomatic scar can be treated with medication, such as the use of Kang Ruibao, Xiliao Tou, cumulonimbus cream and other topical rub, which can play a role in inhibiting the proliferation of keloid scars, but also the use of silicone gel preparations, such as Shou trace, Barker, etc., and the use of Mepiglumine and other topical preparations for the treatment. If the scar continues to proliferate and has no tendency to soften, you can consider taking intradermal injection of glucocorticoids for treatment, such as the use of tretinoin and compound betamethasone, to be injected into the scar, and use the hormone to promote collagen atrophy in the scar, so as to make the scar lighter and flatter.
