treatyourscars Hypertrophi scars are a common complication of burns and injuries in the form of piercings, cuts and acne. They can itch, hurt and restrict mobility due to their narrow joints.
In the case of hypertrophic scars, the additional connective tissue that forms around the original wound remains on the wound. In fact, this type of scar still forms more tissue after the wound heals, which causes the skin to grow. With keloid scars, this additional tissue forms and extends beyond the original scar. Hypertrophic scars and keloids occur when the wound remains in the wound area and extends beyond it.
Hypertrophic scars are similar to keloid scars and the result of an abnormal healing process in which the scar tissue appears wider, thicker and higher above the skin surface. Hypertrophic scars do not grow beyond the original wound boundary, but are thicker and consist of elevated tissue, which is typical of scars that occur after the healing process. They are milder than keloids because they do not grow beyond the limits of the original injury.
Although painful scars are a common surgical procedure, excessive scar tissue formation occurs in 40-70% of patients. Hypertrophic scar formation usually occurs within 4-8 weeks after the injury to the skin. Recurrent scars are minor and, in contrast to hypertrophic scars, the decision to remove pathological scars is usually made postoperatively after radiotherapy has been performed. Certain people may be more prone to hypertrophic scars, which can lead to complications from infection and wound inflammation.
Alternative post-surgical options for refractory scars include pulsed dyes, laser radiation, and imiquimod creams. Options such as cryosurgery, excision, laser and steroid injections should also be explored, despite the risk of further scarring. Early treatment with steroids can reduce the risk of developing a keloid scar, but once the scar has formed, there are limited ways to improve its appearance.
If surgery cannot be avoided, especially in high-risk patients, immediate silicone elastomer films and corticosteroid injections can be initiated. Intraoperative verapamil, fluorouracil, bleomycin, intravenous sulfon alfa 2b injection, topical imiquimod 5 (aldara) is a reasonable study alternative to cortical fosteroids as a treatment for the postoperative prevention. In order to speed up wound healing and reduce skin tension, taping up to 12 weeks after surgery can reduce the risk.
Scarring is a consequence of wound healing process that occurs when body tissue is damaged by a physical injury. After a year, your body rebuilds and tries to improve the scar tissue by itself. During this time, scar problems occur, which can lead to severe scars in the long term.
Scars continue to form after the wound has healed, resulting in large mounds of scar tissue. Hypertrophic scars or keloids are pathological scars that result from an abnormal reaction to trauma, can be itchy and painful, and can cause severe functional and cosmetic disabilities. The American Osteopathic College of Dermatology estimates that keloid scars affect about 10 percent of people, with hypertrophic scars being the most common.
Keloids grow on the skin surface and form large mounds of scar tissue. They occur all over the body, but most commonly around the ears, neck, shoulders, upper arms and chest.
Patients with higher keloid risk are younger than 30 years of age and have darker skin. This group is more susceptible to trauma and has a greater amount of elastic fibres in the skin, which can increase tension and cause irritation and scarring.
For example, if the skin is thin and stretched, the weight of heavy breasts increases the risk of leaving wide, irregular scars. Keloids are fibroblasts of collagen that multiply as the wound fills. They can be large and bulky and cause reddish scars that form at the site of injury or operation.
In some randomized prospective studies there is broad consensus that insoluble triamcinolone acetonide (TAC) (10-40 mg / ml ) is the most commonly used corticosteroid to treat scars when it is the first line treatment for keloids and the second line of therapy for HTSs, other simpler treatments are less effective. TACs in combination with lidocaine reduce the pain associated with injections, but several months of treatment are required to achieve desired results [78].
In 2002, there is a report for the first international guideline for the care and treatment of hypertrophic and keloid scars. Treatment options have been identified in this guide and it has been established that the use of topical silicone gel foils is one of the most important modalities available for hypertrophic scar keloids. It has also been found that IL intralesional corticosteroids are the mainstay in the treatment of HTSs and that they can be used alone or together with silicone gels, which is one of the best modalities for HTS.
The identification of other non-pathological biomarkers could be useful to answer the question of the differences between keloids and hypertrophic scars in their etiology, growth characteristics, and treatment response.
