The maxillary nerve is a nerve located in the face on the human body. The nerve follows a pathway from the cavernous sinus, through the head. At the start of the nerve, it resembles a thin band, but the nerve becomes cylindrical and harder as it reaches the end. The nerve ends on the face, where it's then known as the infraorbital nerve. The nerve consists of four different branches or categories, where the nerve branches off into different areas of the body. The four areas are the infraorbital nerve, pterygopalatine fossa, the cranium, and the face. The term refers to the main portion of the nerve and every time it branches off, it becomes known as a different nerve. Recent studies found that dental and facial surgeries can cause trauma and damage to the nerve.
