Free tissue transfer has revolutionized tissue reconstruction. Microvascular operation techniques using free tissuetransfer make it possible to precisely restore various defects and deformities. There are various surgical flaps availablefor this surgery, such as muscle flaps, musculocutaneous flaps, or fasciocutaneous flaps. The development of perforatorflaps enables multi-component reconstruction with reduced donor site morbidity. Successful reconstruction must beapproached with the goals of not only providing stable coverage, but most importantly, of restoring function. Therefore,the selection of flaps is dependent on the recipient site characteristics and the functional and aesthetic results at boththe recipient and donor sites. With the high success rate of free flaps and the popularization of the perforator flap,microvascular surgery has played a major role in various reconstructive fields.
