When combined with an appropriate sedative protocol, many surgical procedures can now be performed standing, avoiding the cost and risks associated with general anesthesia. The maxillary nerves, which carry important information to the central nervous system (CNS), start from the upper gums (upper row of teeth), travel along the surface of the mid-face, pass through the upper jaw and nasal cavity, and then terminate in the upper lip and cheeks. Then it moves to the inferior orbital fissure and enters into the floor of the orbit, at this point, we can say that the maxillary nerve continues as the infraorbital nerve. It also carries parasympathetic preganglionic fibers (sphenopalatine) and postganglionic fibers (zygomatic, greater and lesser petrosal and nasopalatine) to and from the pterigopalatine ganglion.
