In human anatomy, the pterygopalatine fossa (sphenopalatine fossa) is a fossa in the skull. It is the indented area medial to the pterygomaxillary fissure leading into the sphenopalatine foramen. It communicates with the nasal and oral cavities, infratemporal fossa, orbit, pharynx, and middle cranial fossa through eight foramina.[1]

Boundaries[edit]
It has the following boundaries:
- anterior: superomedial part of the infratemporal surface of maxilla
- posterior: root of the pterygoid process and adjoining anterior surface of the greater wing of sphenoid bone
- medial: perpendicular plate of the palatine bone and its orbital and sphenoidal processes
- lateral: pterygomaxillary fissure
- inferior: part of the floor is formed by the pyramidal process of the palatine bone.
Passages[edit]
The following passages connect the fossa with other parts of the skull:
| Direction |
Passage |
Connection |
| Posteriorly |
foramen rotundum |
middle cranial fossa |
| Posteriorly |
pterygoid canal (Vidian) |
middle cranial fossa, foramen lacerum |
| Posteriorly |
palatovaginal canal (pharyngeal) |
nasal cavity/nasopharynx |
| Anteriorly |

| Laterally |
pterygomaxillary fissure |
infratemporal fossa |
| Inferiorly |
greater palatine canal (pterygopalatine) |
oral cavity, lesser palatine canals |
Contents[edit]
The pterygopalatine fossa contains
- the pterygopalatine ganglion suspended by nerve roots from the maxillary nerve
- the terminal third of the maxillary artery
- the maxillary nerve (CN V2, the second division of the trigeminal nerve), with which is the nerve of the pterygoid canal, a combination of the greater petrosal nerve (preganglionic parasympathetic) and the deep petrosal nerve (postganglionic sympathetic). To obtain block anesthesia of the entire second division of the trigeminal nerve, an intraoral injection can be administered into this area.

- BACKGROUND: Greater palatine nerve (GPN) block is commonly performed for maxillary and palatal anesthesia by using bony landmarks. Ultrasound (US) can be used to consistently identify greater palatine foramen (GPF) as a defect in the bony palate enabling US-guided injections near the foramen.METHODS
