Introduction
In general, cesarean section refers to a surgical procedure known as a cesarean delivery. Postoperative scar hyperplasia after cesarean section may be caused by individual differences, wound tension, skin infection, foreign body irritation, or a predisposition to scarring. Treatment options, as directed by a physician, may include general therapy or medication. Due to individual variations, some people's skin is more sensitive to trauma, making them more prone to developing hypertrophic scars.
Generally speaking, cesarean section refers to a cesarean delivery procedure. Post-cesarean scar hyperplasia may be caused by individual differences, wound tension, skin infection, foreign body irritation, or a scar-prone constitution. Treatment options, as directed by a physician, may include general therapy and medication. The specific factors are analyzed below:
1. Individual Differences
Due to individual differences, some people's skin is more sensitive to trauma and prone to scar hyperplasia. It is recommended to undergo adequate preoperative skin evaluation and maintain wound cleanliness and dryness postoperatively to prevent infection and reduce the risk of scar formation.
2. Wound Tension
The cesarean incision is located on the abdomen, an area with high skin tension. During healing, fibrous tissue may proliferate excessively to resist this tension, leading to scar hyperplasia. Tension-reducing suturing techniques can be used to lower wound tension, while postoperative use of elastic bandages or other supportive measures can further reduce the likelihood of scar hyperplasia.
3. Skin Infection
Improper wound care after cesarean delivery may lead to skin infections, such as Staphylococcus aureus infection. Infection can stimulate excessive proliferation of fibrous tissue, resulting in scar hyperplasia, and may be accompanied by symptoms such as redness, swelling, pain, and exudation at the wound site. Under medical guidance, medications such as amoxicillin-clavulanate potassium, cefuroxime ester granules, and levofloxacin tablets may be used. Additionally, enhanced wound cleaning and care can promote healing.
4. Foreign Body Irritation
During surgery, residual sutures, gauze, or other foreign bodies left in the wound may continuously stimulate fibrous tissue proliferation, causing scar hyperplasia. Symptoms such as localized foreign body sensation and pain may also occur. The foreign bodies should be surgically removed, and medications such as asiaticoside cream, compound heparin sodium and allantoin gel, and vitamin E lotion may be used under medical guidance to aid in scar reduction.
5. Scar-Prone Constitution
Individuals with a scar-prone constitution have abnormally sensitive skin reactions to trauma, and even minor injuries may lead to scar hyperplasia. After cesarean delivery, such patients have a significantly increased risk of scar hyperplasia. In addition to scar hyperplasia, spontaneous keloids may also appear in other areas. Under medical guidance, local injections of medications such as triamcinolone acetonide acetate injection, compound betamethasone injection, and lidocaine hydrochloride injection may be administered to inhibit scar hyperplasia.
After cesarean delivery, strict adherence to medical instructions for wound care is essential, including maintaining cleanliness and dryness and preventing infection.
