Not all scar lesions require surgery, and not all scar lesions are suitable for surgery as soon as they appear. For scar lesions that affect function, damage appearance, or even have the possibility of malignancy, surgery is necessary; scar lesions that do not fall within the above-mentioned scope but are requested by the patient (e.g., those on exposed areas) can also be surgically removed. However, for large HS lesions in non-functional, non-exposed areas, surgical treatment at the cost of a new large trauma is not the right choice.
The timing of surgery for scarring lesions, generally proliferative scarring starts to proliferate roughly 6-8 weeks after trauma, and 3-6 months is the peak period of collagen deposition, then the scar enters a period of relative stability, and most scarring starts to fade after 1 year, but this process may also last 2-3 years or even longer. Surgery during the peak of scar proliferation may induce scar proliferation, so in principle, surgery should be performed during the scar stabilization period. It is generally considered more appropriate to operate after 6 months or even 1 year.
