Pterygomaxillary Fissure And Pterygopalatine Fossa
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. Gross anatomy it is located in the medial aspect of the temporal fossa and is formed by the divergence of the maxilla from the pterygoid process of the sphenoid bone.

Pterygomaxillary fissure and pterygopalatine fossa. Posterior superior alveolar nerve a branch of the maxillary nerve. It exits through the fissure into the infratemporal fossa where it goes on to supply the maxillary molars. A human skull contains two pterygopalatine fossae one on the left side and another on the right side.
It connects the infratemporal with the pterygopalatine fossa and transmits the terminal part of the maxillary artery. Perpendicular plate of the palatine bone. Learn vocabulary terms and more with flashcards games and other study tools.
In human anatomy the pterygopalatine fossa is a fossa in the skull. The pterygomaxillary fissure is a triangular shaped lateral opening of pterygopalatine fossa. It is a triangular interval formed by the divergence of the maxilla from the pterygoid process of the sphenoid.
While in the fossa it gives off the zygomatic nerve which passing into the orbit through the inferior orbital fissure will bifurcate to form the zygomaticotemporal and zygomaticofacial nerves. It is vertical and descends at right angles from the medial end of the inferior orbital fissure. The study aimed to evaluate the pterygomaxillary reg.
Narrowing to the pterygomaxillary fissure. The pterygomaxillary fissure connects the infratemporal fossa with the pterygopalatine fossa see figure 1. Sphenoid bone pterygoid process and inferior aspect of the greater wing roof.
The pterygomaxillary fissure is a fissure of the human skull. Many complications during le fort i osteotomy are encountered during pterygomaxillary separation. The pterygomaxillary fissure is located between the anterior and posterior wall of the pterygopalatine fossa.
It is the indented area medial to the pterygomaxillary fissure leading into the. The maxillary division of the trigeminal nerve enters the pterygopalatine fossa at its posterior boundary via the foramen rotundum. It transmits two neurovascular structures.
It communicates with the infratemporal fossa and transmits the posterior superior alveolar nerve and the maxillary artery. The fossa is located between the pterygoid process and the maxillary tuberosity close to the orbital apex. Start studying pterygopalatine fossa deep midface ii.
Posterior wall of the maxillary sinus. Incompletely formed by the greater wing of the sphenoid bone. The walls of the pterygopalatine fossa are as follows.
