scar revision

Trauma or any type of surgery often leaves scar on skin. For such condition,

scar revision helps remove unwanted scar.

Scar revision is not to regenerate destroyed skin cells but to create smooth skin appearance

by removal of destroyed skin cells.

Proper name for this procedure is scar corrective procedure or scar enhancement procedure.

There are many different types of scars in different forms.

Stretch Marks (Striae)

Stretch marks are originally in thin stripe forms,
but they often get stretched as skin gets pulled.
Stretch marks often appear on extremities and
torso due to trauma or rapid weight gain.

Hypertrophic Scar

Scars with swelling, reddish appearance,
and itchiness are known as hypertrophic scars.
They are more hardened than stretch marks
and raised with irregular surface.
Scars on bony prominence and
wrinkles often become as
hypertrophic scars.

Keloid Scar

Similar to hypertrophic
scars, but Keloid scars
show over growth of scar
margins when hypertrophic scars stay within
the margins over period of time. They may appear
as pink or red initially, but they gradually get darker
with skin irritation. Exact causes are unknown,
but allergic reaction, bacterial infection,
degenerated collagen, hypoxia, and hereditary
factors are mentioned as possible causes.

Caved Scar

Caved scars are formed
when trauma happened
underneath the surface
of skin. Scratch from sharp
objects usually cause injury on deeper
layer of skin - dermis, and when dermis is injured,
it may never be completely regenerated
and create caved surface of the skin.

■ Scar Correction

Suture followed by scar removal can reduce obvious appearance of existing scars.

Redness around surgical site fades after 6 months of operation, and surgical scar also gradually disappears.

W-Shaped Incision W-shaped incision is made on scars to scatter paling force on skin and change
its shape so that the scar will appear less obvious. This method is frequently used to remove scars on forehead,
temples, cheeks, and chin. W-shaped suture may be seen more obvious than scar, but as surgical scar
gradually disappears, the original scar fades as well.
Z-Shaped Incision -shaped incision in made on scar to relocate the surrounding tissue.
It improves its condition by scattering pulling force on skin and changing the original shape of scar.
This method removes scars on front neck. lips, eyelids, and armpits. Z-shaped suture may be seen more
obvious than scar, but as surgical scar gradually disappears, the original scar fades as well.
Oval Shaped Incision Oval shaped incision is made on scar including surrounding tissue to remove
the entire scar. This method is generally used for small size scars or scars with the same texture
as normal skin. Surgical scar may be seen immediately, but it becomes invisible along with original scar site.

■ Tissue Expansion

Scars from severe trauma may restrict joint movement due to pulling force of skin. Tissue expansion improves such condition by using expanding machine to cave: the scar with skin tissue.
1. Insert expander under the normal skin around the scar.
2. Expand the normal skin by insetting saline solution at intervals of about 1 ~2 weeks.
3. Reject scar, cover the rejected side with expanded skin, and suture.

■ Skin Graft

When scars are too big to be treated with scar correction, skin graft may be used.

After removing all destroyed skin tissue, normal skin from unnoticeable places such as hips or scalp is grafted on the side. However, since skin has different characteristics from different parts, special treatment to press the grafted side is required in order to prevent deformity of grafted skin. When patients have not enough excess skin to be grafted, skin flap graft is used. After rejecting scar, skin with blood vessels is grafted on to the rejected site followed by vessel connection to the underlying vessels.

Using bandages for scar prevention
for 3-4 weeks after stitch removal
helps prevent formation
of surgical scar.
Surgical site may appear
and gradually disappears.
We kindly suggest you to stay positive and patient through the recovery process.
For the most effective results,
operation may be divided Into two sessions.
Interval between each operation may take 3-4 months.
Apply ice pack frequently for
2-3 days after surgery.
This will help reduce
swelling and pain.
Individuals with hypertrophic
and Keloid condition must
use silicone sheet for 1-2 months to prevent
recurrence of scar.
You should apply sun blocks to the surgical site to prevent
exposure to sun lights.
