Infratemporal fossa - Fossa infratemporalis
The infratemporal fossa is an irregularly shaped cavity, situated below and medial to the zygomatic arch.
Boundaries are defined anteriorly by the infratemporal surface of the maxilla and the ridge which descends from its zygomatic process; posteriorly by the articular tubercle of the temporal and the spinal angularis of the sphenoid; superiorly by the greater wing of the sphenoid below the infratemporal crest, and by the under surface of the temporal squama; inferiorly, by the medial pterygoid muscle attaching to the mandible; medially by the lateral pterygoid plate; laterally by the ramus of mandible.
