Evolution of the anterolateral thigh free flap.

Purpose of review: To review the recent literature on the evolution and advanced uses of the anterolateral thigh (ALT) free flap in reconstruction of oncologic defects of the head and neck. Recent findings: The ALT free flap is a versatile flap that can be harvested in a chimeric fashion with independent, vascularized skin, muscle, fascia, nerve and bone. Various techniques for chimeric flap harvest and flap inset have been described for reconstruction of pharyngocutaneous, oromandibular and radical parotidectomy defects. These reports expand the indications for the ALT free flap while demonstrating good functional and aesthetic outcomes. Summary: The ALT free flap remains popular for reconstruction of head and neck oncologic defects because of its versatility. Continued evolution in chimeric flap harvest techniques for pharyngocutaneous, osseous and radical parotidectomy defects highlights novel advanced reconstructive uses for the ALT free flap.
