Keloid is an overgrowth of the scar tissue that develops around a wound, usually after the wound has healed. A keloid scar is sometimes confused with a hypertrophic scar. However, keloid usually grows beyond the borders of the original wound whereas in a Hypertrophic Scar the tissue stays within the wound border.
A keloid scar may shrink over time but rarely disappears completely. You may feel you can live with a small scar which is tucked out of sight. However, if you are concerned about its appearance, several treatments are available. As no single treatment is one hundred percent effective and you may be offered a combination of methods.
Treatment options include Intralesional therapy (Steroids), Pressure and/or airtight (occlusive) dressings, Surgery (Not Advisable as removing the keloid scar by surgery can result in an even bigger scar), Cryotherapy, Pulsed dye lasers and Nd:YAG lasers.
Can keloid be prevented? If you are in an at-risk group or have already had a keloid you should avoid body piercing and tattoos. You should also steer clear of unnecessary operations such as cosmetic surgery, especially in those areas of the body where keloid is prone to develop. If you get acne, you should make sure it is treated effectively at an early stage so the spots do not scar. If you are identified as being at risk of keloid and need an operation, your surgeon may offer you dressings, steroid injections or other treatments to reduce the risk of keloid developing.
