Anterior view of sphenoid, zygomatic, and maxilla bones. The maxillary bones form the central portion of the face and house the maxillary teeth and maxillary sinus. The zygomatic bones form the prominences of the cheek. The sphenoid bone is a single bone with multiple parts. The midline body of the sphenoid contains the sphenoid sinus. The greater wings of the sphenoid contain several foramina. In this view, the foramen rotundum can be seen. The pterygoid canal courses within the base of the pterygoid process and is located inferomedial to the foramen rotundum, both of which open into the posterior wall of the pterygopalatine fossa. The space between the lesser wings (not labeled here) and greater wings of the sphenoid is the superior orbital fissure. The space between the greater wing, maxilla, and zygomatic bones is the inferior orbital fissure. (Image courtesy of AL Rhoton, Jr.)
