The infratemporal fossa is located below the greater wing of the sphenoid bone, lateral to the ramus of the mandible and the gap between the zygomatic arch and temporal bone.
It extended inferiorly to the right infratemporal fossa, posteriorly to the petrous bone close to the right carotid canal, inferomedially to the right parapharyngeal space, medially to the right lateral nasal wall, anterosuperiorly to the right orbit through the inferior orbital fissure, superoanteriorly compressing the right optic canal and superoposteriorly to the sphenoid bone.

Although difficult to prove but recurrence in temporal region might be due to seeding into infratemporal fossa during previous resection9.
