The pterygomaxillary fissure is a fissure of the human skull. It is vertical, and descends at right angles from the medial end of the inferior orbital fissure. It is a triangular interval, formed by the divergence of the maxilla from the pterygoid process of the sphenoid.

2024年9月30日 · The pterygomaxillary fissure transmits the posterior superior alveolar nerve, a branch of maxillary division of the trigeminal nerve, coursing from the pterygopalatine fossa to the infratemporal fossa. Terminal branches of the maxillary artery also enter the fissure.

The pterygomaxillary fissure is a narrow gap located at the meeting point of the front and medial walls of the infratemporal fossa. The front wall consists of the rear part of the maxilla, while the medial wall is formed by the lateral pterygoid plate of the sphenoid bone.

2024年7月17日 · Pterygomaxillary Fissure. The pterygomaxillary fissure connects the infratemporal fossa with the pterygopalatine fossa (see figure 1). It transmits two neurovascular structures: 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 ...

2023年7月12日 · The pterygomaxillary fissure is located between the anterior and posterior wall of the pterygopalatine fossa. It communicates with the infratemporal fossa and transmits the posterior superior alveolar nerve and the maxillary artery .

Having analysed fissures, a typological classification was made according to the morphological patterns found. A 2‐mm limiting measure was considered, and Measures A, B and C of each fissure were classified depending on whether they had a …

2025年1月16日 · The meaning of PTERYGOMAXILLARY FISSURE is a vertical gap between the lateral pterygoid plate of the pterygoid process and the maxilla that descends at right angles to the medial end of the inferior orbital fissure and gives passage to part of the maxillary artery and vein.

2023年6月8日 · The pterygomaxillary fissure is a small but important structure in human anatomy, located in the skull near the base of the cranium. It is a narrow channel or groove that separates the pterygoid process of the sphenoid bone from the maxilla, a bone in the upper jaw.

2024年11月27日 · The purpose of this study is to evaluate the height, width and distance of the pterygomaxillary fissure from the zygomatic bone, articular tubercle, and zygomatico-temporal suture. Forty dry human skulls were examined by the Department of Anatomy.

Purpose: The aim of this study was to investigate the detailed anatomy of the pterygomaxillary fissure (PMF) and pterygopalatine fossa (PPF) and variations therein using three-dimensional (3D) cone-beam computed tomography (CBCT) software.
