What passes through the pterygoid fossa?
The pterygopalatine fossa is an important pathway for the spread of neoplastic and infectious processes: medially: communicates with the nasal cavity via the sphenopalatine foramen, which transmits the sphenopalatine artery, the nasopalatine nerve and the posterior superior nasal nerves.
What are the contents of the infratemporal fossa?
The infratemporal fossa contains the mandibular nerve, the inferior alveolar nerve, the lingual nerve, the buccal nerve, the chorda tympani nerve, and the otic ganglion.
What is contained 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.
What is the significance of the infratemporal fossa?
Nerves coursing through and around the infratemporal fossa are responsible for providing a vast majority of sensory and motor function to the lower face and other important structures such as the dura mater.
What is the pterygoid fossa?
The pterygoid fossa is an anatomical term for the fossa formed by the divergence of the lateral pterygoid plate and the medial pterygoid plate of the sphenoid bone. Pterygoid fossa. Sphenoid bone. Upper and posterior surfaces.
Is pterygoid fossa same as pterygopalatine fossa?
Each fossa is a cone-shaped paired depression deep to the infratemporal fossa and posterior to the maxilla on each side of the skull, located between the pterygoid process and the maxillary tuberosity close to the apex of the orbit….
What travels through infratemporal fossa?
The middle meningeal artery is one of the larger branches that courses superiorly and passes through the superior wall of the fossa via the foramen spinosum.
What drains into pterygoid plexus?
The pterygoid plexus drains many deep structures of the head, including the palate, nasal cavity, paranasal sinuses, nasopharynx, auditory tube and deep parts of the scalp in the temporal region. It is continued by a short maxillary vein, which lies deep to the neck of the mandible.
What is pterygoid 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 connects the infratemporal fossa to the orbit?
It communicates with the nasal and oral cavities, infratemporal fossa, orbit, pharynx, and middle cranial fossa through eight foramina. Left maxillary sinus opened from the exterior….Passages.

Where is the pterygoid fossa?
The pterygoid fossa is an anatomical term for the fossa formed by the divergence of the lateral pterygoid plate and the medial pterygoid plate of the sphenoid bone . The lateral and medial pteryoid plates (of the pterygoid process of the sphenoid bone) diverge behind and enclose between them a V-shaped fossa, the pterygoid fossa.
What are the upper and posterior surfaces of the pterygoid?
Upper and posterior surfaces. (Pterygoid fossa labeled at left.) The pterygoid fossa is an anatomical term for the fossa formed by the divergence of the lateral pterygoid plate and the medial pterygoid plate of the sphenoid bone .
What is the pterygopalatine fossa (PPF)?
Dr Yuranga Weerakkody ◉ and Dr Behrang Amini et al. 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 inferior to the orbital apex.
What runs through the medial pterygoid plate?
Pterygoid canal – runs from the middle cranial fossa and through the medial pterygoid plate. It carries the nerve, artery and vein of the pterygoid canal. Pharyngeal canal – communicates with the nasopharynx. It carries the pharyngeal branches of the maxillary nerve and artery.
