1

Define the following terms:
Blepharoplasty
P572

Eyelid surgery—removing excess
skin/fat

2

Define the following terms:
Face lift
P572

Removal of excess facial skin via hairline/
chin/ear incisions

3

Define the following terms:
FTSG
P572

Full Thickness Skin Graft

4

Define the following terms:
Langer’s lines
P573 (picture)

Natural skin lines of minimal tension
(e.g., lines across the forehead), incisions
perpendicular to Langer’s lines result in
larger scars than incision parallel to the
lines

5

Define the following terms:
Mammoplasty
P573

Breast surgery (reduction/augmentation)

6

Define the following terms:
Polydactyly
P573

Extra fingers

7

Define the following terms:
Rhinoplasty
P573

Nose surgery, after trauma or cosmetic

8

Define the following terms:
STSG
P573

Split Thickness Skin Graft

9

Define the following terms:
Syndactyly
P573

Webbed fingers

WOUND HEALING
What are the phases of
wound healing?
P573

Think: “In Every Fresh Cut” = IEFC:
1. Inflammation
2. Epithelialization
3. Fibroplasia
4. Contraction

11

WOUND HEALING
What are the actions of the
following phases:
Inflammation?
P574

Vasoconstriction followed by vasodilation,
capillary leak

12

WOUND HEALING
What are the actions of the
following phases:
Epithelialization?
P574

Epithelial coverage of wound

13

WOUND HEALING
What are the actions of the
following phases:
Fibroplasia?
P574

Fibroblasts and accumulation of collagen,
elastin, and reticulin

14

WOUND HEALING
What are the actions of the
following phases:
Wound contraction?
P574

Myofibroblasts contract wound

15

WOUND HEALING
What is the maximal
contraction of a wound in
mm/day?
P574

0.75 mm/day

16

EPITHELIALIZATION
What degree of bacterial
contamination prevents
epithelialization?
P574

>100,000 organisms/gm tissue (10(5))

17

EPITHELIALIZATION
In which structures does the
epithelium grow from
superficial burns/wounds?
P574

Epithelial lining of sweat glands and hair
follicles

18

EPITHELIALIZATION
In full-thickness burns?
P574

From wound margins, grows in 1 cm
from wound edge because no sweat
glands or hair follicles remain; this
epithelium has no underlying dermis

19

EPITHELIALIZATION
What malignant ulcer is
associated with a longstanding
scar/burn?
P574

Marjolin’s ulcer (a.k.a. burn scar
carcinoma)

20

WOUND CONTRACTION
What are myofibroblasts?
P574

Specialized fibroblasts that behave like
smooth muscle cells to pull the wound
edges together following granulation

21

WOUND CONTRACTION
Which contracts more: an
STSG or an FTSG?
P574

STSG contracts up to 41% in surface
area, whereas an FTSG contracts little,
if at all

22

WOUND CONTRACTION
What is granulation tissue?
P575

Within 4 to 6 days after an open wound,
development of capillary beds and
fibroblasts provides a healthy base for
epithelial growth from wound edges; this
tissue also resists bacterial infection

23

WOUND CONTRACTION
Name the local factors that
impair wound healing.
P575

Hematoma, seroma, infection, tight sutures,
tight wrap, movement/disturbance of the
wound (i.e., poking it with a finger)

24

WOUND CONTRACTION
What generalized conditions
inhibit wound healing?
P575

Anemia
Malnutrition
Steroids
Cancer
Radiation
Hypoxia
Sepsis

25

WOUND CONTRACTION
What helps wound healing
in patients taking steroids?
P575

Vitamin A is thought to counteract the
deleterious effect of steroids on wound
healing

26

WOUND CONTRACTION
When does a wound gain
more than 90% of its
maximal tensile strength?
P575

After ≈6 weeks

27

WOUND CONTRACTION
Define the following terms:
Laceration
P575

Jagged wound

28

WOUND CONTRACTION
Define the following terms:
Abrasion
P575

Superficial skin removal

29

WOUND CONTRACTION
Define the following terms:
Contusion
P575

Bruise without a break in the skin

30

WOUND CONTRACTION
Define the following terms:
Hypertrophic scar
P575

Hypertrophic scar within original wound
margins
