1. Definisi2. Perbedaan antara Grafts & Flaps3. Klasifikasi Skin Grafts4. Tipe Skin Grafts5. Indikasi Skin Grafts6. Donor Sites
EPIDERMIS DERMIS
EPIDERMIS Tidak terdapat
pembuluh darah. Stratified squamous
epithelium composed primarily of keratinocytes.
Separated from the dermis by a basement membrane.
DERMIS Composed of two “sub-
layers”: superficial papillary & deep reticular.
The dermis contains collagen, capillaries, elastic fibers, fibroblasts, nerve endings, etc.
GraftSkin Graft adalah pemindahan jaringan epidermis dan dermis dari tempat asal (donor site) pada tempat baru dengan suplai pembuluh darah baru.
FlapRekonstruksi jaringan atau penutupan luka menggunakan jaringan dengan mempertahankan suplai pembuluh darah yang lama
GraftDoes not maintainoriginal blood supply.
FlapMaintains original bloodsupply.
1. Autografts – A tissue transferred from one part of the body to another.
2. Homografts/Allograft – tissue transferred from a genetically different individual of the same species.
3. Xenografts – a graft transferred from an individual of one species to an individual of another species.
Grafts are typically described in terms of thickness or depth.
Split Thickness: Terdiri dari 100% epidermis dan sebagian dermis. Split thickness grafts are further classified as thin or thick.
Full Thickness: Terdiri dari 100% epidermis dan dermis.
Type of Graft Advantages DisadvantagesThin Split Thickness
-Best Survival-Heals Rapidly
-Least resembles original skin.-Least resistance to trauma.-Poor Sensation-Maximal Secondary Contraction
Thick Split Thickness
-More qualities of normal skin.-Less Contraction-Looks better-Fair Sensation
-Lower graft survival-Slower healing.
Full Thickness
-Most resembles normal skin.-Minimal Secondary contraction-Resistant to trauma-Good Sensation-Aesthetically pleasing
-Poorest survival.-Donor site must be closed surgically.-Donor sites are limited.
Phase 1 (0-48h) – imbibisi plasmadifusi nutrisi dari permukaan resipien
Phase 2 – InosculationPembuluh pada graft terhubung dengan permukaan resipein.
Phase 3 (day 3-5) – pertumbuhan neovaskuler,revakularisasi graft terjadi melalui pertumbuhan pembuluh baru menuju dasar luka.
Vaskularisasi yang baik pada dasar luka Immobilisasi kontak permukaan graft &
resipien Jumlah hitung bakteri rendah
Faktor sistemik Malnutrisi Sepsis Medical Conditions (Diabetes) Medications
Steroids Antineoplastic agents Vasonconstrictors (e.g. nicotine)
Tendon Luka terinfeksi Area yang mengalami radiasi
Luka yang luas. Luka bakar. Luka post infeksi yang mengalami
kehilangan kulit luas. Bedah rekonstruksi : bedah kosmetik.
• Tidak diprioritaskan untuk kosmetik• Ukuran luka yang terlalu besar untuk full
thickness
1. Chronic Ulcers2. Temporary coverage3. Correction of pigmentation disorders4. Burns
Undikasi fullthickness :1. Jaringan penunjang mengalami lesi yang luas
atau jaringan yang telah dilakukan flap2. Lokasi spesifik : nasal tip, forehead, eyelids,
concha, and digits.
The ideal donor site would provide skin that isidentical to the skin surrounding the recipient
area.Unfortunately, skin varies dramatically from one
anatomic site to another in terms of:
- Colour- Thickness- Hair - Texture
What would be the best donor site for a graft of the cheek?
A donor site above the clavicles would provide the best color and texture match. In particular the postauricular area is a good choice.
Cover the deficit with a skin graft Achieve healing as swiftly as possible
without any complications Maintain patient comfort Maintain cost effectiveness.
Graft site to extremities must remain Immobile for 5 days with a split skin graft Elevasikan ekstrimitas yg terdapat luka
graft Elevate grafted leg/s on pillows. Grafts to the lower
extremities require bed rest for a period of 5 days. If hands or feet are grafted or across
joints, splints must be insitu to immobilise the graft site to avoid shearing forces
Circulation observations may be requested for 24 hours post operatively
Assess for signs of active bleeding, indications of active bleeding
Integrity of the dressing must be assessed. It is essential that the graft site remains dry and intact for 5 days with a split skin graft and approximately 7 - 10 days with a full thickness skin graft.
