Supra fascial dissection of Lateral arm flap (LAF) is a relatively new modified versatile flap that could be elevated as a fascial or Fascio cutaneous flap; type B pattern of circulation according to Naha's classification (Ninkovic et.al, 2001). The flap depends on interseptal perforators between lateral arm compartments. It can be used for different resurfacing reconstructive purposes in variable small to medium sized soft defects. Its ability to be elevated as a pedicled flap or a free flap to give it a versatility benefits to resurface many body defects as in the dorsum of the hand, the lower limb, or the head & neck. This flap shows reliable blood supply with ease of dissection and no major vessel sacrifice. It has a thin pliable content and relatively hidden donor site scarring underneath dressed arm. On the other side, the main disadvantages are relatively small diameter of its vasculature, numbness and pain at lateral arm & upper forearm due to possible injury of lateral cutaneous nerve of arm or Radial nerve injury. (Graham et al., 1992)
This review article aims at discussing, briefly, the lateral arm flap; surgical techniques, indications and contraindications and flap imaging, based on, metanalytic and clinical studies.
