Thickness of split grafts commonly used in oral and maxillofacial region:: (A) Upto 0.3mm, (B) 0.6 mm, (C) 0.3-0.5 mm, (D) >0.6 mm
Answer is C. The split thickness graft consists of epidermis and the superficial part of dermis, thus containing few skin appendageal structures. The grafts are classified as thin (upto 0.3mm), medium (0.4 — 0.5mm) and thick (about 0.6mm). Split grafts of 0.3 to 0.5mm thickness are commonly used in oral and maxillofacial procedures.
