With robotic-assisted platforms, the surgeon views the panorama of the myopectineal orifice with a new lens (to quote Robert Bendavid in this context). In this chapter, these partially rediscovered anatomical structures are placed in the new robotic-assisted navigation context. The following pages provide one of the most comprehensive summaries of endoscopic (posterior) anatomy, and include a new concept of explanatory illustrations and, in part, specimens made specifically for the chapter. The concept of the fascia intermedia is discussed and a new traction fascia, the fascia flabiliformis, is described. Embryological layers are discussed as navigational aids in the context of parietalization and the differentiation of lipomas based on their blood flow will help to overlook fewer inguinal canal lipomas in the future. This chapter is a comprehensive compilation of current knowledge, with practical application.
