Scars occurring physiological response of our organism to an alteration of any of the tissues that comprise. Skin, when margins are well faced wounds, scarring often of good quality, but in some cases appear hypertrophic and keloid scars.
Hypertrophic scars are elevated, reddish, hard and inelastic lesions, causing itching or pain. However, not invade surrounding healthy tissue and have a tendency to spontaneous regression, although sometimes very slow. Keloids are called, however, few scars grow beyond the margins of a skin lesion, from an abrasion or injury. These lesions develop a much wider and widespread respect at home scar damage, invading the surrounding healthy tissue and not prone to spontaneous regression (unexpected improvement or cure).
At first, the keloid scar looks like a simple high as the lesion has a smooth, hairless and translucent. In this initial phase, keloids are a deep red color that are vascularized, ie with sufficient blood and lymphatic vessels in the tissue.
Subsequently, scar begins to extend and protrude, significantly exceeding the limits of the initial injury. It is at this point that the keloid shows a pink color and texture becomes increasingly thick and hard. On the surface the keloid has no hair follicles in which to grow hair or sweat glands.
Although these lesions may appear on any area of skin affected by abrasions or wounds, some areas of the body seem to be more sensitive. Are more common in the deltoid region of the body (shoulder), sternum and upper back. The lobes of the ears and the back of the neck are other quite common objectives of keloids.
There are factors that predispose to scarring, both local type (healing by secondary intention, misdirection of the scar, harmful agents that cause burns) and systemic (young age, black race, female). Apart from these factors, there are several treatments for hypertrophic scars and keloids:
- Pressure Therapy: This controlled compression system responsible for moving the venous and lymphatic flow can be an effective way to improve the clearance of cellular fluid and improve the flow of oxygen to the affected area method.- Massage- Cortisone: Cortisone injections to flatten the affected area elevated through its ownership of tissue atrophy- Substances that inhibit collagen synthesis local- Cryotherapy: The treatment is to apply freeze-thaw sessions in order to flatten the affected area.- Silica gel: Apply a bandage with silicone gel to moisturize the scar and prevent water loss through evaporation of injury.- Interferon: Another injection can combat scars is injections of interferon - proteins produced in response to pathogens -.- Surgical therapy (with or without brachytherapy / radiotherapy): The surgery removes scars by removing. Keloids tend to recur.
Before deciding on any treatment, see your specialist to diagnose the injury and apply a solution to meet your medical history.
