What Causes Keloid Scars?

Understanding Keloid Scars

Keloid scars are defined as scars that grow beyond the boundary of the site of a skin injury. The scar is a increased and ill-defined growth of skin in the region of skin.

Some cultural groups are at a greater risk of developing them Even though anyone can be formed on by a scar. African Americans and Hispanics tend to be 16 percent more vulnerable and keloid scars are seen 15 times more often in groups than in Caucasians.

Some regions of the body do appear more susceptible to scars, including the deltoid region of the sternum, the top back, and the upper arm. The earlobes and the back of the throat are also common sites.

Reasons

Why or keloid scars kind, it is not fully understood. Skin trauma seems to be the most common cause, although scars may also form for no apparent reason. Skin or muscle strain seems to contribute to keloid formation, as is evidenced by the most frequent sites of the formation (the top arm and spine ). But if this was the full story, you would expect that other sites, like their hand’s hands or the soles of their feet, to be just as exposed.

Infection at a wound site, repeated injury to the exact same area, skin pressure or a foreign body at a wound may also be factors. There does appear to be a genetic element to scarring: it’s known that if a person in your family has keloids, then you are at risk.

Other theories for the causes of keloid scarring comprise a deficiency or an excess in melanocyte hormone (MSH); diminished proportions of mature collagen and increased soluble collagen; or the blocking of very little blood vessels and the resulting lack of oxygen.

Some work is being done to find the reason, while the absence of a theory does demonstrate the absence of understanding of the condition. Determining the exact cause will mean better preventative medication and more effective treatments in the future, however there are many problems with sufficient follow up of individuals with the condition, lack of a clear cut-off from treatment, and also few studies in general — all hampering the search for a remedy.

Prevention?

The simple fact is that there may be little you can do if you’re unfortunate enough to have the sort of skin which reacts by forming scarring. It is possible to assist the healing process by keeping any wounds clean, and then you may avoid taking risks, if you know you are susceptible due to a household relationship or past experience. Don’t get piercings or tattoos, and be sure that you tell your doctor if you’re likely to get surgery.

There’s a higher rate of recurrence: around 50 percent. Some doctors say that all highly pigmented people should prevent piercings and tattoos to be on the secure side.

Remedy?

There are three treatment options for scars:

Surgical removal
non-surgical interventions
combination remedies.
Surgical Treatment for Keloid Scars

This is the complex of the forms of treatment, the recurrence ​rate is thought to be roughly 50 percent. Lasers have been tried as an alternative to knife surgery but so much the results are better.

Non-Surgical Treatments for Keloid Scars

Interferon treatment (medication acting on the immune system) was reported as successful in reducing keloid scarring; however, it does have significant side effects. Cases are flu-like symptoms, toxicity, depression, nausea, and vomiting.

The viability of the option is based upon the location of the keloid, although compression of scar tissue can soften and break up keloid scars. Include Verapamil, vitamins, nitrogen mustard, antihistamines, and amino acids.

Combined Remedies for Keloid Scarring

1 option involves removal of scar tissue in combination with a couple of steroid injections -one at the time of this surgery and the injection about a month afterwards.

Another alternative combines kind radiotherapy and surgery. Radiation has the effect of interfering with skin growth (fibroblasts) and collagen production. On which sort of combination therapy is better, research changes.

Both radiotherapy and steroid drugs have side effects, and therefore you need to go over with your doctor the most effective treatment. It may be worth having a second opinion before proceeding with treatment
