Fascial relationships of the infratemporal region

Written by Lőrinczi Zoltán, Nemes Orsolya Sarolt oh.

The autors, intrigued by the mismatches found in the literature, intended to establish the real pattern of the subtemporal fasciae. Dissections have clearly dismissed the so-called interpterygoid fascia, and a clear-cut retropterygoid intermuscular septum is promoted instead. This layer acts as an impenetrable fence between the masticatory and parapharyngeal regions. A further epipterygoid fascial sheet was also revealed, stretching at one point across the foramen ovale being intermingled with the basal dura mater. The authors call attention on practical issues deriving from the anatomical variability of the nearby elements.
