Is infratemporal fossa and pterygopalatine fossa same?
In addition, the infratemporal fossa communicates medially with the pterygopalatine fossa through the pterygomaxillary fissure and anteriorly with the orbit through the inferior orbital fissure. The infratemporal fossa has four well-defined walls which are as follows: anterior, lateral, medial, and superior (roof).
Is Sphenopalatine fossa and pterygopalatine fossa same?
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.
What is in the infratemporal fossa?
The infratemporal fossa is the space between the skull base, lateral pharyngeal wall, and the ramus of mandible.
What are the two fossae of the temporal?
The temporal region can be subdivided into two main regions: the superior region (temporal fossa) and the inferior region (infratemporal fossa), separated by the zygomatic arch. The temporal fossa represents the wide area of the lateral skull above the zygomatic arch.
What is in the pterygopalatine fossa?
The pterygopalatine fossa also contains multiple important structures. This fossa contains the pterygopalatine ganglion. Nerve roots from the maxillary nerve suspend this ganglion. The PPF contains the terminal third segment of the maxillary artery.
Is pterygopalatine fossa part of infratemporal fossa?
The infratemporal fossa is a complex area located at the base of the skull, deep to the masseter muscle. It is closely associated with both the temporal and pterygopalatine fossae and acts as a conduit for neurovascular structures entering and leaving the cranial cavity.
What connects the infratemporal fossa to the pterygopalatine fossa?
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….

What passes through the pterygopalatine fossa?
The pterygoid canal is located on the posterior wall of the pterygopalatine fossa, between the foramen rotundum and the palatine canal. It communicates with the middle cranial fossa and from there, it transmits the nerve, artery, and vein of the pterygoid canal.
