Performing procedures to reshape the arm requires understanding the aesthetic arm deformity and its causes. Brachioplasty, liposuc­tion, and non-invasive body shaping may all be used for arm shaping or contouring. Women interested in shaping the arm who would like to improve along the deltoid region and over the triceps are good candidates for liposuction of the arm. Upper extremity liposuction is appropriate for younger patients with fatty collections and good skin quality. Skin is relatively thin in the arm, so skin retraction is less likely in the standard patient than abdomen or back. Skin laxity is possible after liposuction, and if this is anticipated, it is best to discuss the potential need for second-stage skin removal. Liposuction treatment is often weighed against arm lift with the possibility of a visible scar. Weight loss leads to variable degrees of skin redundancy. Some patients receive help from a minimal incision arm lift. In contrast, others receive help from traditional arm lifts, and others have so much laxity that the arm lift needs to be extended beyond the axilla along the lateral chest wall. There is an increasing number of transcutaneous energy delivery devices currently available. They are classified according to the type of energy they deliver to their target—mechanical (e.g., suction, massage), radiofrequency, ultrasound, cryolipolysis, and laser.
