Wound hyperplasia can be recognized by having symptoms such as widening and protruding scar and local itching. The main manifestations of wound scarring are localized itching, localized congestion of the scar, swelling and prominence, and localized fleshy red granulation tissue hyperplasia. There are many reasons for scarring, mainly related to personal constitution and wound care. Keloid hyperplasia can occur easily after wound infection. Individuals belong to the keloid constitution and are more prone to keloid hyperplasia. During the recovery of the wound, attention should be paid to disinfection, keep the local dry and clean, which is conducive to the fading of the scar after recovery. If the patient has a more obvious tendency to keloid proliferation, the symptoms can be relieved by applying scar removal ointment, and if the scar has a more obvious pain and itching sensation, the scar can also be removed by surgery.
