2024年9月30日 · The pterygomaxillary fissure is a triangular shaped lateral opening of pterygopalatine fossa. It is located between the infratemporal fossa, laterally, and the pterygopalatine fossa, medially, and it is formed by the AP divergence of the maxilla from the lateral pterygoid plate of the sphenoid bone 3.

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.

Pterygomaxillary fissure is a triangle-shaped hole which is found among the body of maxilla and lateral pterygoid plate of sphenoid. The lateral portion of the pterygopalatine fossa is constant by the infratemporal fossa via a large gap by the pterygomaxillary fissure.

In this work, an anatomical analysis was performed of the morphological characteristics of the 242 fissurae pterygomaxillares, which corresponded to 121 adult patients, 58 males and 63 females, aged between 18 and 87 years. For each subject, right and left fissures were studied with radiological computed tomography images.

内侧边界是腭骨的垂直板（perpendicular plate）及其眶突（orbital process）和蝶突（sphenoidal process）。 外侧边界是翼上颌裂（pterygomaxillary fissure）。 翼腭窝内的结构包括上颌内动脉的第三段（翼腭段），上颌神经及其分支， 翼腭神经节 等。 翼腭窝的前内侧观 (Standring, 2016)。 尸体翼腭窝区冠状面CT（A）和解剖（B）对比 (C. 引言： 翼腭窝（pterygopalatine fossa）位于颞下窝深面，是一个隐藏在颅骨外侧深面的一个狭小的间隙。 翼腭窝内神经血管 …

2024年11月27日 · The perpendicular fissure that descends at a right angle from the medial end of the inferior orbital fissure is known as the pterygomaxillary fissure. From the infratemporal fossa to the pterygopalatine, the maxillary artery passes through the pterygomaxillary fissure before ending as a third segment of the maxillary artery.

2024年7月17日 · The main trunk of the maxillary nerve leaves the pterygopalatine fossa via the infraorbital fissure. Here, it enters the infraorbital canal of the maxilla and exits below the orbit in the infraorbital foramen to contribute to the sensory innervation of the face (figures 2.0 & 2.1).

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.

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.

The pterygomaxillary fissure is a triangular-shaped opening that provides communication between the pterygopalatine fossa and the infratemporal fossa. It can be seen on the anterior superomedial aspect of the infratemporal fossa.
