In the field of Ear, Nose and Throat, or ENT, surgery, defects to the mandible and/or maxilla caused by injury or disease are often repaired using an osteocutaneous scapula flap harvest technique. This involves careful dissection of the tip of the scapula bone and a workable length of vascular pedicle that includes an arterial supply and venae comitantes. Special attention must be given to the angular branch of the TDA (and its anatomical variants), which supplies the scapula tip. Depending on the defect, the bone flap may be accompanied by a skin flap, or as shown in this animation, a flap of latissimus dorsi muscle.

Purpose
This 3D animated video, intended for surgical fellows in the field of Ear, Nose and Throat, or ENT, surgery, introduces viewers to the surgical plan for an osteocutaneous scapula flap harvest technique. Beginning with patient position and anatomical landmarks, the animation highlights the major steps in dissection, with special attention given to the angular branch of the TDA, which supplies the scapula tip.
