Video 1. This video shows: Arm positioning: 90_º abduction at the shoulder in neutral flexion, internal rotation to 90_º and elbow flexed at 90_º. Marking: Deltoid area is marked with black, surrounding the posterior and intermediate fascicles of the muscle. The proximal shadow limits the liposuction over the teres muscles, while also addresses the deltoid insertion (humerus tuberosity) and the dynamic zone between the triceps and the deltoid, by internal and external rotation of the shoulder joint at 90_º abduction. Negative spaces and fat deposits are marked with green, as well as the posterior axis of the arm, which will guide the posterior projection.
