The infratemporal fossa is connected to other spaces in the skull. It is connected to the middle cranial fossa by the foramen ovale and the foramen spinosum. It is connected to the temporal fossa, which lies deep to zygomatic arch. It is connected to the pterygopalatine fossa through the pterygomaxillary fissure.
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 structure connects the external auditory canal to the infratemporal fossa. Reduction in thickness of the temporal bone may also occur in the same location. [2] During development of the skull, the foramen tympanicum normally closes by the age of 5 years. The foramen, however, may persists in rare cases resulting in its presence in adults.
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 ...
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 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.
The temporal fossa is a fossa (shallow depression) on the side of the skull bounded by the temporal lines above, and the zygomatic arch below. Its floor is formed by the outer surfaces of four bones of the skull.
The anterior part of the lateral surface is rough, for articulation with the tuberosity of the maxilla; its posterior part consists of a smooth triangular area which appears, in the articulated skull, between the tuberosity of the maxilla and the lower part of the lateral pterygoid plate, and completes the lower part of the infratemporal fossa.
