Hypertrophic
Scarring and Keloids
Hypertrophic scarring
and
keloids
occur due to an abnormal response to trauma or injury.
After a wound or an incision from surgery has occurred to the epidermis, both
skin cells and connective tissue cells called fibroblasts begin multiplying to
repair the damage. All scars are made up of “connective tissue” and fibroblasts
to help close the wound. The hypertrophic scar
is one that is widened, but yet does not extend beyond the original boundaries
of the wound or incision. Hypertrophic scars
tend to reach a certain size in which they eventually stabilize or revert and
eventually they might fade with time. Hypertrophic scars normally do not get as
big as keloids either, and can be present in all
racial groups. Whereas keloids tend to target
racial groups which have a lot of melatonin in their skin, such as African
American, Asian or Pacific Islander. Treatments for hypertrophic scars include
Silicone Sheeting
and creams that seem
to help with the appearance of the scar, and it usually takes 3 months or more
to see an improvement.
Keloids on the other hand are not as common as
hypertrophic scars
and only affect 10% of the people are considered benign tumors. These
keloids appearance is raised
red growths above the surface of the epidermis and form large mounds of scar
tissue. Keloids
are nothing more than abnormal scar tissue that grows beyond the boundaries of
the original site of the skin injury – the fibroblasts continue to multiply even
after the wound is filled in. The upper chest area, shoulders, and upper back
are all areas where keloids tend to form. Some of the symptoms associated with
keloids include pigmentation of the skin, pain, itchiness and redness.
Keloids are raised dome shaped shiny scars ranging in
color from pink, red or purple. Treatments include
cryosurgery (freezing),
excision, laser, x-rays, and steroid injections.

Keloid Scarring

Keloid Scarring

Keloid Scarring

Keloid Scarring

Treatments:
The best and first line treatment of a keloid is to inject long-acting cortisone
(steroid – such as Kenalog or Celestone Soluspan)
once a month. After several injections with
cortisone, the keloid usually becomes less noticeable and flattens out within
three to six months time.
Excision or scar revision
surgery: This
can be risky with a patient that is prone to keloids. If surgery with a scar
revision is considered, some surgeons like to inject steroids or apply a
pressure dressing to the wound site after cutting away the affected keloid.
Radiation is also considered after the excision of the affected area, so the
keloid will not grow back.
Cryosurgery: Liquid
Nitrogen is used to destroy tissue of both benign and malignant lesions by the
freezing and re-thawing process. Applying liquid nitrogen does flatten out the
keloid scar and is effective, but the side effect of this treatment is
hyper-pigmentation after the fact.
Interferon: is
being used with some success with keloid scars. Interferon has been evaluated
for efficacy in managing many diseases that involve the immune system.
Injections of interferon into the actual keloid have shown promise in reducing
the size of keloids, though it's not yet certain whether that effect will be a
permanent result.
Pulse-dye Lasers:
are also another method of reducing the sign of the
keloid scar. These lasers tend to soften up the excessive scar tissue with
making the scar flattened and less red. This treatment is very safe and not
very painful; however it might take several treatments to see an improvement.
Silicone Sheeting (ReJuveness):
has helped many patients with their keloid
scarring, however this method of treatment takes several months of wearing a
sheet of silicone gel. Some doctors prefer “compression bandages” which have
helped some see a positive end result. Both methods require a lot of time and
patience on the part of the patient. Silicone Sheeting has been around since
the early 1980’s, and some patients have seen a remarkable difference in the
appearance of keloid or hypertrophic scarring. Silicone sheeting is soft and
pliable and will mold to any part of the body. ReJuveness Silicone Sheets
can also last up to 6 months or has been proven effective on old raised red
scars (up to 20 years old) as well as newly formed scars.

Scar Guard offers four different treatments for the management of scars
(old and new) – and is the most powerful and effective treatment developed.

scar from irritation while delivering silicone cortisone and vitamin E
throughout the day.

layer of silicone on the scar.

to use."

Other
Topical Treatments:
Mederma:
Mederma comes
as a silicone gel and also a new cream, which has a SPF-30 in it to protect the
scar from the sun. The main ingredient is Cepalin, which is a proprietary
botanical extract which comes from onions. According to a small Pilot study
evaluating topical onion extract as treatment for post-surgical scars –
published by
PubMed – August 25, 1999, authors B.A. Jackson and A.J.
Shelton, found that this main ingredient in Mederma concluded the following:
“Topical onion gel extract was ineffective in improving scar erythema and
pruritus in our patients.” Most patients who have tried Mederma have suffered
some sort of allergic reaction to it because of the onion extract, making the
scars more angry looking than before treatment.”
Vitamin E:
helps by working on the
collagen fibers and makes a scar softer and more pliable. However, in a double
blind study, found that Vitamin E was indeed ineffective in reducing the
symptoms of a hypertrophic scar or keloid.
Bio-Oil:
Bio-Oil
is a specialist skin care product that is recommended for scars, stretch marks,
uneven skin tone, aging, and dehydrated skin. It is formulated for use on both
the face and body. product
has improved the appearance of regular scars tremendously; however has very
little effect on hypertrophic scars or keloids.
Retin-A:
Retinoic
Acid or Tretinoin is derived from Vitamin A. Retinol, which is a less potent
form of Retin-A also has some very strong medical studies backing the
effectiveness of this type of topical cream to help with scar formation.
This is a prescription formulation of Vitamin A, and is marketed under the brand
names of Retin-A Micro, Renova, Avage, and Tazorac. There is also the less
potent over the counter products called Retinol. After your surgical wound has
closed up completely, applying Retin-A to the scar fades out the redness it
might have and helps with exfoliating the area. At first, Retin-A can actually
make the area look worse with redness, flakiness and peeling, for up to eight
weeks. But by 24 weeks, patients will see dramatic marked improvements. Retin-A
along with the application of steri-strips helps with keeping tension off of the
incision site, so a thin scar will form.
