Endoscopic views of harvesting LD muscle flap. a After the lateral border of LD muscle is harvested with electrocautery (Bovie), the submuscular layer is dissected with energy device. b Then, the subcutaneous layer is also dissected with energy device and large vessels are ligated with metal clips. c, d When the subcutaneous and submuscular layers of LD muscle is sufficiently dissected, muscle boundaries are transected with energy device with traction of LD muscle
