Scar tissue refers to the fibrous connective tissue formed by the remodeling of granulation tissue. At this time, the tissue consists of a large number of bundles of fibrous connective tissue that are parallel or staggered. Fiber bundles tend to be homogenous red stained, ie, glassy. Fibroblasts are rare, the nucleus is elongated and darkly stained, and blood vessels in the tissue are reduced. In general, it is in a partially contracted state. It is pale or grayish-white translucent, hard and tough, and lacks elasticity. Surgical resection is the main method for depressed scars, atrophic scars, and hypertrophic scars. However, no scar can be completely removed by any surgical procedure. It is only to maximize the risk of ameliorating or correcting scars, and after surgery. New scars should be formed. Z-scar correction is a surgical method in which a scar is cut into a zigzag shape and the position of the surrounding skin tissue is changed. Divide the strength of the skin due to scars to improve the direction of the scar. It is particularly suitable for small scars such as the front of the neck, mouth corners, double eyelids, armpits, etc. After surgical suturing, although there will be a Z-shaped line, it is not easy to see over time than straight scars.
Therapeutic effects: long-term maintenance of the right crowd: Patients with Z-type scars Recovery time: 1 week
1. Applicable to relatively small scars such as the front of the neck, mouth corners, double eyelids, armpits. 2. The wound after surgery is relatively small.
1. The wound is relatively large. 2. There may be new scars afterwards.
1. The wound may crack after surgery. 2. Complications such as infection and poor wound healing may occur at the surgical site. 3. Bleeding and hematoma may occur at the surgical site.
Suitable for small scars such as the front of the neck, mouth corners, double eyelids, armpits, etc.
1, scar physique.
2. Inflammatory skin diseases such as chronic radioactive dermatitis, purulent skin disease, recurrent herpes simplex, acne with obvious inflammation, and pigmented dry skin disease.
3, abnormal blood disease or coagulation mechanism.
4, mental patients or various mental disorders.
5, have severe diabetes or heart, lung disease and severe hypertension.
3. Preoperative preparation
1, do not make up before surgery.
2. Do not take aspirin-containing drugs for two weeks before surgery to avoid reducing platelet coagulation.
3. Patients with hypertension and diabetes should inform the doctor in detail before the operation.
4. Women must avoid the menstrual period during surgery.
4. Treatment and process
Scars are cut into Z-shaped surgical methods for changing the position of the surrounding skin tissue. Divide the strength of the skin due to scars to improve the direction of the scar. It is particularly suitable for small scars such as the front of the neck, mouth corners, double eyelids, armpits, etc. After surgical suturing, although there will be a Z-shaped line, it is not easy to see over time than straight scars.
5. Treatment effect
Scars fade or fade away much more than before surgery.
Infection, local hematoma, scar hyperplasia, wound cracking.
7. Rehabilitation and Nursing
1. After 2-3 days of surgery, doing more cold compresses can greatly help pain and prevent swelling.
2. After the stitches are removed for 3-4 weeks, the band-aid that prevents scars will continue to be applied to prevent scars after surgery.
3. In the first 2-3 months after surgery, the operative marks will be a bit red, and then will become more and more shallow.
8. Risks and Prevention
1. The wound may crack after surgery.
2. Complications such as infection and poor wound healing may occur at the surgical site.
3. Bleeding and hematoma may occur at the surgical site.
9. Physiology and Aesthetics
Various wounds, burns, surgeries, infections, and injections can cause skin pathological scars. The formation of scars is the process of repairing tissue damage. Scars are the marks formed after the skin tissue is healed. When the skin is deeply damaged by the reticular layer of the dermis, the healing of any wound is accompanied by different degrees of scar formation. The matrix of the scar is connective tissue and the main component is collagen fibers.
According to the surface morphology and histological and clinical characteristics, common scars can be divided into flat scars, hypertrophic scars, atrophic scars, depressed scars and contracture scars. Among them, flat scars generally only involve the epidermis and superficial dermis, the degree of skin tissue damage is lighter; hypertrophic scars are caused by deeper burns, incisions, surgery, infections, etc. involving the formation of the dermal layer of the skin dermis; atrophic scar often Occurs in a large area of deep lesions, especially deep wounds after subcutaneous tissue healing. Depressed scars are formed after healing of subcutaneous tissue or deep tissue injury. There are also some superficial depressed scars such as acne scars; Acne scars are more common after deep burns have healed. They often occur around the joints and organs, affecting the function of the parts and causing serious damage.
