Split-Thickness Skin Graft (STSG)

   
 Thin STSG: 0.005–0.012 in
Medium STSG: 0.012–0.018 in
Thick STSG: 0.018–0.030 in
 
   
  • Epidermis + partial-thickness dermis
  • STSGs are categorized further as thin (0.005-0.012 in), intermediate (0.012-0.018 in), or thick (0.018-0.030 in) based on the thickness of dermis
  • Advantages: ability to cover large defects (especially if graft fenestrated), higher likelihood of survival as less metabolic demand, allows for detection of tumor recurrence in cutaneous oncology
  • Disadvantages: less cosmetically desirable color and texture, granulation tissue at donor site, increased contracture at wound site (more than with FTSG), lack adnexal structures (do not produce sebum, hair, sweat)
  • Donor sites: buttocks, thighs, arms, abdomen
  • One week postop: pink to skin-colored
