Infratemporal Fossa
The subtemporal fossa is the caudal continuation of the temporal fossa. The name comes from the relation to the m. temporalis. The fossa continues as fossa pterygopalatina.
Boundary
Cranially: facies infratemporalis ossis sphenoidalis, pars squamosa ossis temporalis
Ventrally: tuber maxillae
Dorsally: spatium prestyloideum
Medially': lamina lateralis processus pterygoidei ossis sphenoidalis, processus pyramidalis ossis palatini
Lateral: ramus mandibulae
