For the elimination of hypertrophic scars, one can apply anti-scarring ointment to the surface early after surgery. If the patient indeed has a scarring constitution, at the end of the surgery, it is advisable to inject medications into the subcutaneous area or within the wound tissue to prevent excessive or abnormal scar proliferation. If necessary, radiotherapy can be applied; under the effect of X-rays, it can effectively prevent the abnormal proliferation of scar tissue and the abnormal and excessive growth of fibroblasts. If there is already hypertrophic scarring, one might consider excising the hypertrophied scar tissue and re-suturing the wound.
