Skin graft

1. History of the Procedure
• 2500-3000 years ago – India
• the mid-to-late 19th century - Reverdin
• Ollier's and Thiersch's uses of the split-thickness graft in 1872 and 1886
• Wolfe's and Krause's use of the full-thickness graft in 1875 and 1893
• Today, skin grafting is commonly used in dermatologic surgery.

2. SKIN GRAFT
• Skin Grafts, Full-Thickness
• Skin Grafts, Split-Thickness
• Skin, Grafts

3. INDICATIONS
• Reconstructing a defect in the skin, regardless of the cause
of the defect
✔primary closure
✔second-intention healing
✔local skin flaps are inappropriate or unavailable,
✔would produce a suboptimal result.

4. INDICATION -examples
• cutaneous malignancies
• chronic nonhealing cutaneous ulcers
• tissue lost in full-thickness burns
• hair to areas of alopecia.

7. FTSG
Epidermis Dermis
✔ External - stratified squamous
epithelium - keratinocytes
✔ no blood vessels
✔ receive nutrients by diffusion
✔ 2 layers=papillary + reticular
Papillary D.
Thinner & Loose conn.tiss
capillaries, elastic fibers, reticular fibers, and
some collagen
Reticular D.
thicker layer & dense conn. Tiss.
larger blood vessels, collagen
fibers, fibroblasts, mast cells, nerve endings,
lymphatics, and epidermal appendages.

9. GRAFT SELECTION
Advantages Disadvantages
• LIMITED TO:
❖relatively small
❖contaminated
❖poor-vascularized wounds
❖ Donor sites must be closed
primarily
❖resurfaced with a split-thickness
graft.
✔ ideal for visible areas of the
face
✔less contraction while healing
✔grow with individual

10. DONOR SITE SELECTION
MATCH BE AWARE
• cancerous lesion at the donor
site
• may grow hair later in life
• Inconspicuous-donor site
• easily closed primarily
✔Thickness
✔Texture
✔Pigmentation
✔Presence or absence of hair

11. DONOR SITE SELECTION
Face and neck OTHER PART
• hairless groin skin
• dorsum of the foot
• wrist flexion crease
• elbow creasely
✔the upper eyelid
✔nasolabial fold
✔Preauricular
✔postauricular regions
✔the supraclavicular fossa
harvesting bilaterally to maintain
facial symmetry is often aesthetically
preferable!!!

12. WOUND PREPERATION
will not survive will survive
✔Periosteum
✔Perichondrium
✔Peritenon
✔Perineurium
✔Dermis
✔Fascia
✔Muscle
✔ granulation tissue
On tissue with a limited blood
supply:
❖Bone
❖Cartilage
❖Tendon
❖Nerve
❖secondary to radiation

13. WOUND PREPERATION
oVascularity
oHemostasis
oDebride all necrotic tissue / slough
oOptimize co-morbid conditions

14. EXAMPLES

15. OPERATIVE TECHNIQUE
HARVESTING
VIDEO
• https://www.youtube.com/watch?
v=hxwAlZj8Tf4
• Cleansing of the wound
• Hemostasis: igation, gentle pressure,
application of a topical vasoconstrictor (eg,
epinephrine), or electrocautery.
• Full-thickness skin grafts are harvested with a
scalpel.
• The donor site may then be infiltrated with local
anesthetic with or without epinephrine.
• After incising the pattern, the skin is elevated
with a skin hook, keeping a finger of the
nonoperating hand on the epidermal side of the
graft.
• Any residual adipose tissue must be trimmed
from the underside of the graft
• The donor site is then closed primarily
• Full-thickness grafts may be pie-crusted to allow
egress of wound fluid from beneath the graft.

16. OPERATIVE TECHNIQUE
PLACING
VIDEO
• h
• Recipient site for hemostasis.
• Place the graft with the dermal side down.
• Prevent wrinkling or excessive stretching of the
graft
• Suturing or stapling the graft to the surrounding
wound bed.
• Critical point sutures are placed to hold the graft
in the proper orientation.
• Passing the needle first through the graft and
then through the surrounding wound margin is
helpful to prevent lifting of the graft from the
wound bed.
• The sutures should approximate, not
strangulate, the skin edges. -/+ central sutures
• Pressure dressing immobilize the graft, avoid
shearing, and prevent seroma or hematoma
formation beneath the graft

17. Graft Survival
oAdherence 0- 8 hours max
oThe graft imbibes –2-3days
oRevascularization of the graft begins at 2-3 days
ofull circulation - 6 or 7 days postgrafting.
oContraction up to 6-18 months following grafting.

18. Graft Failure
oHematoma
oSeroma
oMovement of the graft
oShear forces
oPoor recipient site
oTechnical error
oExcess pressure

ANY QUESTIONS?

29. • Flap or skin graft
• Graft is from one side into completely other area
• Revascularization = ingrowing of vessel
• Hemostasis
• Pressure dressing ( prevent from seroma, hematoma, immobilization
of graft)
• Immobilization of recipient area
• Scalp for the face (STSG) reharvesting
