Medially, the infratemporal fossa communicates with the pterygopalatine fossa via the pterygomaxillary fissure, which is contiguous with the inferior orbital fissure and, thus, the orbit. Each fossa is a cone-shaped paired depression deep to the infratemporal fossa and posterior to the maxilla on each side of the skull, located between the pterygoid process and the maxillary tuberosity close to the apex of the orbit. The pterygopalatine fossa (PPF) is a cone-shaped depression deep to the infratemporal fossa and posterior to the maxilla on both sides of the skull. the vascular supply of the pterygopalatine fossa originates from the infratemporal fossa via the internal maxillary artery, and v2, the vidian nerve, and the palatine nerves course through the pterygopalatine fossa. This means the pterygopalatine fossa's neighbours include the middle cranial fossa, infratemporal fossa, orbit, nasal cavity, the roof of the oral cavity, and maxillary sinus and the pharyngeal vault . pterygopalatinum Vidian sinir 8.

The pterygopalatine fossa (PPF), less commonly known as the sphenopalatine fossa , is a small but complex space of the deep face in the shape of an inverted pyramid located between the maxillary bone anteriorly, the pterygoid process posteriorly, and orbital apex superiorly. The fossa is closely associated with both the pterygopalatine fossa, via the pterygomaxillary fissure, and also communicates with the temporal fossa, which lies superiorly (figure 1.0). The upper head is smaller and arises from the greater wing of sphenoid, while the larger lower . 1) The orbit Via inferior orbital fissure.

These openings mostly transmit nerves and blood vessels, and they are as following: A human skull contains two pterygopalatine fossaeone on the left side, and another on the right side. It is connected to the temporal fossa, which lies deep to zygomatic arch. The pterygopalatine fossa lies just posterior to the posterior wall of the maxillary sinus. The walls of the pterygopalatine fossa feature canals and foramina that connect this space with other regions of the skull such as the orbit, nasal cavity and oral cavity, middle cranial fossa, and infratemporal fossa. It is located lateral to the nasal cavity, anterior/inferior to the middle cranial fossa, inferior to the apex of the orbit, and medial to the infratemporal fossa.
