Perforator flaps in head and neck surgery.
A 'perforator flap' is a flap of skin or subcutaneous tissue that is based on the dissection of a 'perforating vessel'. Over the past few years a large number of 'perforator flaps' have been devised and described. By reducing any muscle harvest and trauma to a minimum, perforator flaps aim to minimize donor site morbidity whilst providing the reconstructive surgeon with more versatility than other flap types. The principal perforator flaps are discussed, particularly those employed in head and neck reconstruction including 'free style perforator flaps'. Methods of locating perforating vessels for the use of perforator flaps are described. The technique of perforator flap harvest is illustrated as exemplified in the anterolateral thigh perforator flap. Advantages in the use of this flap for head and neck reconstruction are discussed and are compared with that of non-perforator flaps, particularly the Radial Forearm Flap. The role of the primary thinning of perforator flaps is discussed. The versatility of the anterolateral flap is discussed, which may well supersede the Radial Forearm Flap as the principal soft tissue flap used in head and neck surgery.
