The boundaries of the infratemporal fossa occur: anteriorly, by the infratemporal surface of the maxilla, [1] and the ridge which descends from its zygomatic process. This contains the alveolar canal. posteriorly, by the tympanic part of the temporal bone, [1] and the spina angularis of the sphenoid.
The infratemporal space (also termed the infra-temporal space or the infra-temporal portion of the deep temporal space) [1] is a fascial space of the head and neck (sometimes also termed fascial spaces or tissue spaces). It is a potential space in the side of the head, and is paired on either side.
The lateral surface of the greater wing of the sphenoid is convex, and divided by a transverse ridge, the infratemporal crest, into two portions.. The superior or temporal portion, convex from above downward, concave from before backward, forms a part of the temporal fossa, and gives attachment to the Temporalis; the inferior or infratemporal, smaller in size and concave, enters into the ...
The posterior superior alveolar nerve of the maxillary nerve goes from the pterygopalatine fossa to the infratemporal region via this fissure. The pterygopalatine plates are separated laterally from the posterior surface of the body of the maxilla by the pterygomaxillary fissure.
Chorda tympani then exits the skull by descending through the petrotympanic fissure into the infratemporal fossa. Here it joins the lingual nerve, a branch of the mandibular nerve (CN V 3). Traveling with the lingual nerve, the fibers of chorda tympani enter the sublingual space to reach the anterior 2/3 of the tongue and submandibular ganglion ...
It runs across the floor of this fossa [2] along a groove oriented in the direction the foramen ovale and situated parallel and anterolateral to the groove for the greater petrosal nerve and its groove. [3]: 509 It exits the skull via canaliculus innominatus [4] and enters the infratemporal fossa. In the fossa, its fibres synapse at the otic ...
After branching off the maxillary artery in the infratemporal fossa, it runs through the foramen spinosum to supply the dura mater (the outer meningeal layer) and the calvaria. The middle meningeal artery is the largest of the three (paired) arteries that supply the meninges, the others being the anterior meningeal artery and the posterior ...
It connects the orbit (anteriorly) with the infratemporal fossa and pterygopalatine fossa (posteriorly). [1]: 397 ... Left infratemporal fossa.
