Proliferative scars and keloids are a difficult problem in the international medical community, and there is no quick and efficient treatment method, and the recurrence rate of various treatments is high. However, they can be cured with persistent treatment; I currently use comprehensive treatment means in the scar clinic, skin grafting, soft tissue expansion, flap transfer repair, subepidermal scar removal, scar grinding, microdermabrasion, drug injection, isotope dressing, laser treatment and topical application, oral medication, etc. However, since keloids are extremely prone to recurrence, surgical excision alone is not advocated. Patients with surgical excision must adhere to regular drug injections after surgery, otherwise they are prone to recurrence. Generally, the drug is injected once every 3-4 weeks at the beginning, and gradually extended to once every 6-8 weeks after the scar has subsided, and the dosage of the drug is reduced until it is gradually stopped. The treatment period takes 1 year. The medication should not be stopped until the scar is healed, otherwise it is very likely to recur. The effect of injectable medication on fertility, patients who are planning to have children are reminded to schedule: as medication during pregnancy may affect fetal development, it is recommended not to have children or breastfeed during treatment. It is recommended to stop the medication for six months before pregnancy. Patients who need to have children in a short period of time are recommended to have children before having drug injection therapy (including male patients). May cause menstrual disorders in female patients. Side effects may disappear after drug reduction or discontinuation. Caution is required for high-dose long-term treatment in the elderly and infirm, young children, osteoporosis, hepatic and renal insufficiency, diabetes mellitus, chronic infection, peptic ulcer, hypertension, glaucoma patients, and is contraindicated in patients with hypersensitivity to glucocorticoids. Scar growth is caused by surgery, burns, other skin injuries deep to the dermis, more severe trauma, uneven surgical incisions, and often accompanied by wound contamination. There is no obvious family history of scarring. Scarring can be caused by skin injury or can have no obvious cause (acne, scratching). There is often a family history. Preferred sites are on the forehead, shoulders, outer upper arms, earlobes, and other areas of high skin tension, often with multiple occurrences for inexplicable reasons. The injury exceeds the original injury limit, and even has the possibility of infinite enlargement. In the process of proliferation, it can infiltrate the surrounding normal skin and turn even normal skin into keloid, which is close to the manifestation of skin tumor. However, there can often be no obvious symptoms, and the occasional pain and itching is lighter. Our department is a key discipline in Guangdong Province, treating tens of thousands of scars of all kinds. Over the years, we have accumulated a lot of experience, using a combination of surgical and non-surgical treatments to maximize the ideal results, greatly solving the troubles of the majority of patients, and being quite influential at home and abroad. Treatment scope – deformities and defects caused by burns, trauma, etc.: 1, facial and neck scar, limb and trunk scar, perineal scar contracture, scarring alopecia, skin and soft tissue defects and depression deformities; 2, eyelid ectropion, eyelid defect, nasal defect, nostril stenosis or atresia, auricular defect, external ear canal atresia, lip and cheek defect, lip ectropion, small mouth deformity, perioral scar contracture; 3, hand trauma and its various deformities and dysfunctions, finger defects, peripheral nerve injuries and dysfunctions, cranial defects; 4, facial palsy, decubitus ulcers, radioactive ulcers, chronic skin ulcers. The following methods are commonly used: 1.scar excision and suturing: suitable for the treatment of small area scars. The scars are directly removed and sutured together, and the stitches are removed in 5-12 days, which basically does not affect work. 2.Dermal soft tissue expansion: Suitable for patients with large scars, who cannot be directly pulled together and sutured after excision, and who have a certain amount of normal skin around the scars. In this method, a water bladder with the ability to expand is embedded under the skin, and the water bladder is injected regularly to enlarge the water bladder and then the normal skin around the scar is expanded and the area is increased, and then the scar is removed and the normal skin around the scar is covered. The advantage of this method is that the color and texture of the skin after surgery is consistent with the surrounding normal skin, and the appearance is good, which is the most ideal method to repair large scars. The disadvantage is that the treatment period is long, the expansion time takes about one month, and it takes 1 – 2 months to prepare before and after the surgery. 3.Dermabrasion: It is suitable for the treatment of depressed scars left by facial acne, chicken pox, smallpox, trauma, etc. The edges of the scars are ground into a slope through grinding to achieve the purpose of visual depressions that are not obvious. It is the better solution for depressed scars at present. 4.Scar deformity correction: A method of deformity correction by reshaping scars through flap transfer or skin implant. 5.Scar excision and skin grafting: It is suitable for patients with large scar area and local functional disorder. The procedure involves removing normal skin from other parts of the body (e.g. thighs, scalp, back) and implanting it into the scar excision site to improve appearance and restore function. Be aware that the procedure is not recommended for women during menstruation.
