PURPOSE OF REVIEW: The anterolateral thigh free flap has achieved recent popularity in North America for the reconstruction of head and neck defects after ablative surgery. The flap is most often based on either the septocutaneous or musculocutaneous perforators of the descending branch of the lateral circumflex femoral artery. Its versatility allows for a subcutaneous, fasciocutaneous, myocutaneous, or adipofascial flap to be obtained. RECENT FINDINGS: Recent publications have described the utility of the anterolateral thigh flap for reconstruction of head and neck defects. It has been used successfully in the reconstruction of the laryngopharynx, oral cavity, oropharynx, external skin, and maxilla. Furthermore, when a thinner flap is needed, a suprafascial anterolateral thigh flap may be raised or the flap may be thinned after it is obtained. SUMMARY: The anterolateral thigh flap is a highly versatile and reliable flap for use in the reconstruction of various soft tissue defects of the head and neck. This flap has gained great popularity in mainland China, Taiwan, and Japan given its versatility, ability for a two-team approach, and minimal donor site morbidity. However, it has not met the same enthusiasm in Europe and North America because of the relative difficulty in perforator dissection, reported variations of the vascular anatomy, and the presumed increased thickness of the anterolateral thigh tissue in the Western population in comparison with the patient population of the Far East. These obstacles may be overcome by increased surgical experience and by the ability to create a thinner suprafascial flap or thinning the flap after it has been obtained.
