• W3199088009 abstract "INTRODUCTION The anterolateral thigh (ALT) flap has become the workhorse flap for soft-tissue reconstruction of head and neck defects.1 This perforator-based fasciocutaneous flap is ideal due to its thin, pliable nature and long vascular pedicle. It can include the vastus lateralis muscle for added bulk or tensor fasciae latae for strength, or can be thinned to skin and subcutaneous fat.1 The vascular pedicle supply is the descending branch of the lateral circumflex femoral artery with a length as long as 18 cm.2 Up to 10 × 25 cm of skin paddle can be harvested without compromising closure of the donor site.3 It can also be made into a sensate flap via the anterior branch of the lateral cutaneous nerve of the thigh.2 It results in minimal donor site morbidity when harvested in either the sub- or suprafascial plane, without functional muscle loss.4 Finally, the ALT also allows for a two-team surgical approach, yielding a more efficient operative experience for the patient and surgeons involved. (See Video 1 [online], which displays introduction and indications for an anterolateral thigh flap for head and neck reconstruction.) {href:Single Video Player,role:media-player-id,content-type:play-in-place,position:float,orientation:portrait,label:Video 1.,caption:ALT introductions and indications.

Perforators are often located approximately midway on a line drawn from the anterior-superior iliac spine to the lateral patella, corresponding to the septum between the rectus femoris and vastus lateralis muscles.5 The flap is then drawn as an ellipse, to match the required defect size, often centering the ellipse over the strongest Dopplerable perforator(s).

(See Video 3 [online], which displays intramuscular perforator dissection and microsurgical technique for the anterolateral thigh flap.) {href:Single Video Player,role:media-player-id,content-type:play-in-place,position:float,orientation:portrait,label:Video 3.,caption:Microsurgical technique.

Biopsy and radiographic scan revealed a T2N1p16+ squamous cell carcinoma of the right tonsil. He was initially treated with chemotherapy and radiation. Several months later, he was found to have a recurrence and was treated with radical robotic surgical tonsillectomy with clear margins. Several months following surgical resection, he was found to have a second recurrence of his squamous cell carcinoma. The second recurrence required a two-team surgical approach. The otolaryngologists performed oncologic ablative surgery including a right oropharygectomy and neck dissection of lymph node levels I–IV. At the same time, the plastic surgeons raised an ALT flap on musculocutaneous perforators. The ALT provided adequate coverage of the oropharyngeal defect. (See Video 4 [online], which displays intraoral anterolateral thigh flap inset). All the surgical steps are described in vivid detail in our supplemental videos (See Videos 1–4 [online]). {href:Single Video Player,role:media-player-id,content-type:play-in-place,position:float,orientation:portrait,label:Video 4.,caption:ALT inset.

Understanding the salient points of ALT harvest technique is essential for the head and neck reconstructive surgeon to master." @default.
