Figure 6: Local anesthetic injected posterior to the maxillary tuberosity or into the greater palatine foramen may reach the orbital apex (not in view) by entering the pterygopalatine fossa. The red wire shows the straight-line path from the greater palatine foramen (GPF) to the pterygopalatine fossa (PPF), and its continuation with the inferior orbital fissure (IOF)
