Scar is a natural part of the healing process for most dermal wounds - they are a normal consequence of the body's natural healing response. As the normal healing process takes place, most scars do not produce poor cosmetic or functional results. The original scar tissue is gradually replaced during the healing resulting in a reduction in redness, remodeling of the scar tissue to produce a flat, soft, pale scar that is level with the adjacent skin. When the ideal healing process is not achieved, abnormal scar tissue which is usually known as keloid will forms.
There are a few types of scar presentation:
a) Hypertrophic scar (elevated, red, firm and thickened scar surround the wound)
b) Atrophic scar (flat and depressed below surrounding skin, often caused by pimples or chicken pox)
c) Keloid scar (The keloid is defined as an abnormal scar that grows beyond the boundaries of the original site of skin injury. Keloids have the clinical appearance of a red, raised amorphous growth and are frequently associated with pruritus and pain, Certain areas of the body such as the sternum, deltoid region of the upper arm, and upper back, have increased susceptibility to keloid formation. These areas are also subject to elevated levels of muscle and skin tension, which may explain their association with keloids.
Various options are available for the treatment of scars, depending on its site, type and severity. The treatment options includes:
2. Intralesional steroid injection
3. Pressure garments
4. Silicone gel sheets
5. Surgical revision
