Although interest in buttocks implant procedures is growing around the world, it remains a technically demanding procedure. The intramuscular plane is thought to be superior to other planes of dissection. Asymmetry and visibility of the implants remain frequent complications when the surgeon works without any reference points to guide the procedure. The XYZ method helps the surgeon to obtain symmetry, to significantly reduce implant visibility and to decrease other complications associated with buttocks implants. The method uses the surface anatomy of the boney frame of the pelvis to perform a geometric plane to detach the muscle.
