Keloid Scar Treatment
Every skin wound heals by forming a scar. Scars can be delicate and imperceptible or large and unsightly. Wound healing and scar formation depends on several factors, including: size and location of the injury, mechanism of the injury, age of the patient and genetic predisposition to keloid or hypertrophic scar formation. African Americans and Asians have a greater predisposition to developing hypertrophic or keloid scars. In fact, deeply pigmented people of all races are more prone to keloids than those with fair skin and may require facial reconstructive surgery. The skin of the ears, the jaw line, the shoulders and the central chest is especially predisposed to keloid formation.
Keloids and hypertrophic scars can be troublesome not only due to their aesthetic effects, but also due to functional disturbance they may cause. Hypertrophic scars are wide, thick scars that grow within the borders of the original incision. Keloid scars, on the other hand, grow beyond the confines of the original skin incision or scar. Keloids can grow to become massive, causing emotional harm and functional damage in affected patients.
Keloid Scar Removal
Hypertrophic scars are treated with steroid injections, coverage with silastic sheets, surgical removal, or a combination of these remedies. In general hypertrophic scars are easier to manage, and have a lower risk or recurrence. Keloids have a greater chance of recurrence. Keloids are managed by steroid injections when they are very small. Larger keloids require surgical removal followed by steroid injections. Recurrent or large keloids may require surgical excision followed by radiation therapy.

Frequently Asked Questions
What causes keloids?
The exact cause of keloids is not yet clearly described. The suspected problem is abnormalities in cell proliferation whereby the process of healing is not halted normally. Scar tissue continues to build, leading to large and unsightly scars. There are genetic factors that predispose patients to keloid scar formation. Hormonal factors also affect the risk of keloid formation. Because keloids tend to demonstrate accelerated growth during puberty or pregnancy and tend to resolve with menopause. Other hormones linked to keloid formation include thyroid hormone alterations and melanocyte-stimulating hormones.
How many steroid injections would I need after a keloid removal?
This is a clinical decision that depends on the patient and the extent of the keloid. In general, three injections are recommended at one month intervals.
Do lasers offer an advantage in treatment of keloids?
The pulsed dye laser has shown some benefit in treatment of keloids, through suppression of fibroblast proliferation.
What is the likelihood of a keloid returning after it's removed?
There are widely reported success rates for treatment of keloids. Success rates vary from 50% to 90%. Keloid scars that have failed to resolve with standard therapies, such as excision and steroid injections, can respond to combination of surgical excision followed by radiation therapy.
How many radiation sessions are required for treatment of keloids?
Surgical excision is usually followed by one radiation session on the same day or the next day.
What causes hypertrophic scars?
Hypertrophic scars are caused by excess tension across wounds. Other factors implicated in the etiology of abnormal scar formation include wound infection, a prolonged inflammatory response, and wound orientation different from the relaxed skin tension lines.
Can I get body piercing if I have had a keloid?
In patients who have keloids or history of keloids in their immediate family, it is advisable body piercing be avoided. In fact, all non-essential surgical treatments that violate the skin should be avoided.
Keloids and hypertrophic scars are generally treated as stand alone procedures. Keloid treatment may require post surgical radiation therapy. In most cases, keloid and hypertrophic scars are treated with post surgical steroid injections on monthly basis.
