Damage or loss of skin/tissue through
Disease
pathological process (disease)
Trauma – Damage or loss through
1. Burns
traumatic event
2. Frostbite – necrosis may require
amputation
3. MVA – motor vehicle accident

5. Piercing injuries
Cosmetic alteration – addition or
1. Congenital defects
replacement of tissue or removal of excess
2. Scars
or unwanted tissue

metastasizes
A = asymmetry
2. Squamous cell (SCCA) – may

to 1% of SC patients.

often presents as mole that has
changed color, size, appearance
Burns and Plastic Surgery
Burn Assessment Techniques
1. Identify the burn agent
2. Classify the burn
3. Assess the burn
CONTACT WITH:
Identify the burn agent
1. Thermal – fire, hot object/fluid
2. Chemical – corrosive/irritating
3. Electrical – overexposure – deep
damage than apparent
4. Radiation – sunlight, x-rays,
nuclear explosions, radium
1. First degree – superficial – outer
Classify the burn
epidermal layer – quick healing
2. Second degree – epidermis and
part of dermis, moist pink surface
with blisters – slow to heal. Loss of
body fluids and increased infection
risk
3. Third degree – full thickness to
epidermis, dermis and subq – dry,
pearly-white or charred appearance
– eschar forms over dry, destroyed
skin. No sensation. Needs skin graft
4. Fourth degree – “char burns”
extends into bones, tendons and
muscles. Extensive debridement
and skin graft required.
Assess the burn
1. Adult’s Rules of Nines
2. Pediatric Lund-Browder chart
Adult Rules of Nines – divides body into
1. Head and neck = 9%
sections = to multiples of 9%
2. Torso,anterior,posterior = 18% each
3. Upper extremities = 9% each
4. Lower extremities = 18% each
5. Perineum = 1%
Pediatric Lund Browder Chart – based 1. A =1/2 head 9-1/2% (0) – 3-1/2% adult
on burn location and age
2. B = ½ thigh 2-3/4% (0) – 4-3/4% adult
3. C = ½ leg 2-1/2% (0) – 3-1/2% adult
4. D = torso 13% child
5. E = arms = 2% upper, 1-1/2% forearm,
1-1/2% hand.
Plastic Surgery Treatments
Treatment or removal of tissue, lesions
1. General treatment
or scars
2. Burn Treatment
3. Lesion Treatment
4. Liposuction
1.Chemical peel – chemical burn to skin to
General treatment
activate new growth
2. Cryosurgery – freezes tissue/cancer
cells
3. Curettage/cautery – leaves larger scar
4. Debridement – removes dead/damaged
tissue and debris from wound/burn prior to
skin graft/dressing
5. Dermabrasion – smoothing skin by
“sanding” with dermabrader
6. W, Z, Y-V plasty – scar revision
technique involve excision and closure of
scars
1.Amputation – needed to stop infection
Burn Treatment
2.Contracture release – renew elasticity to
scar tissue
3. Escharectomy – excise eschar down to
fascia, covered with biologic dressing 3-5
days, STSG follows
4. Escharotomy – bilateral incision to
remove eschar crusted, necrotic, burned or
diseased tissue. Incision to fascia relieves
pressure, improves circulation and prevents
further necrosis
5. Fasciotomy – Incision extended through
the fascia if escharotomy fails
6. Replacement – skin grafts or tissue flaps
7. Tangential excision – burn tissue excised
until normal debris is reached.
1. Cryosurgery – defect frozen with super

cooled elements.
2. Excision – primary closure or graft of op
site
3. Laser – area of skin CA laser beam tx
4. Mohs – exc. Advanced, recurrent skin
CA with minimal removal normal tissue
5. Radiation – skin CA tx with x-rays
6. Topical chemotherapy – anticancer drugs
applied directly to skin lesions 2-3 wks
(Efudex – common tx)
Exc. Fat deposits via metal cannula/suction
Skin grafts and Plastic Surgery
Skin graft donor options
1. Homograft – tissue donor same species,
Homo/hetero used as “biologic” dressings. primarily cadaver skin
Stimulate epithelium formation, promote
2. Hetero-xenograft – tissue donor
growth of granulation tissue, enhance
different species, commonly pigskin

3. Autograft – tissue from patient’s body
Auto graft May be harvested and preserved. Wrap in
