Systematic review reveals lateral thigh paresthesia is the most frequent complication of anterolateral thigh flap harvesting, suggesting nerve preservation minimizes morbidity.
Lateral thigh paresthesia is the most common complication. Severe complications such as compartment syndrome and muscle necrosis can occur, but are rare. Preservation of the lateral cutaneous nerve of the thigh, femoral motor nerve branches and deep fascia decreases the risk of complications. The degree of vastus lateralis disruption did not show a significant impact on musculoskeletal dysfunction.
