Veins of pterygopalatine fossa (Latin)

The main venous structure seen in the fossa pterygopalatina is the plexus venosus pterygoidei. This plexus drains to multiple different venous structures: posteriorly to the v. palatina major, that accompanies the course of the a. maxillaris; anteroinferiorly to the v. facialis and v. facialis profunda; and medially to the sinus cavernosus, which is an intracranial venous structure located adjacent to the sella turcica.
