Where is the Pterygomaxillary fissure?

Where is the Pterygomaxillary fissure?

temporal fossa
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. It connects the infratemporal fossa with the pterygopalatine fossa.

Where is the Hamular notch?

Hamular notch: a notch lying between the maxillary tuberosity and the center of the vault of palate. Tours palatinus: it is excessive hard bony enlargement or extosis that form rounded elevation at the center of the vault of the palate.

What is Pterygopalatine fissure?

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.

What is in the Hamular notch?

a groove or notch at the base of the pterygoid hamulus that forms a pulley for the tendon of the tensor veli palatini muscle.

What is the function of the Hamular notch?

Prior to dissecting away mucosa and submucosa, the intact hamular notch is a shallow concavity which is the chosen location for extension of the denture base. Mucosal movement is negligible during function.

Where is the pterygopalatine fossa?

The pterygopalatine fossa (PPF) is a small, clinically inaccessible, fat-filled space located in the deep face that serves as a major neurovascular crossroad between the oral cavity, nasal cavity, nasopharynx, orbit, masticator space, and the middle cranial fossa.

What goes through pterygopalatine fossa?

The inferior orbital fissure forms the superior boundary of the pterygopalatine fossa and communicates with the orbit. It is a space between the sphenoid and maxilla bones. The zygomatic branch of the maxillary nerve and the infraorbital artery and vein pass through the inferior orbital fissure.
