Types of Scar

01

Stretch Marks(Striae)

늘Stretch 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 external injury or rapid weight gain.

02

Hypertrophic Scar

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

03

Keloid Scar

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

04

Caved Scar

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

Scar Correction

■ Scar Correction

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

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

01

W-Shaped Incision

W-shaped incision is made on scars to scatter pulling
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,
and chin. W-shaped suture may be seen more obvious than scar,
, but as a surgical scar gradually disappears,
the original scar fades as well.

02

Z-shaped Incision

Z-shaped incision is made on a scar to relocate the
surrounding tissue. It improves its condition dispersing the
the pulling force on skin and changing the original shape
shape of scar. This method removes relatively smal
scars on front neck lip corners, eyelids, and armpits.
. Z-shaped suture may be seen more obvious than scar,
but as a surgical scar gradually disappears, the original scar fades as well.

03

Oval Shaped Incision

Oval shaped incision is made on a 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
becomes invisible along with the original scar site.

■ Tissue Expansion

Scars from severe injury may restrict
joint movement due to
the pulling force of skin.

1. Insert expander under the normal skin

around the scar.
2. Expand the normal skin by inserting saline

solution at intervals of about 1~2 weeks. 3. Resect scar, cover the resected site
with expanded skin, and suture.
