Localisation of the pterion and its relationship with the middle meningeal artery in Romanian human skulls

Localisation of the pterion and its relationship with the middle meningeal artery in Romanian human skulls.

Understanding the relationship between the pterion and its surrounding anatomical structures, including the middle meningeal artery (MMA), is important for expanding anatomical
knowledge, in addition to being relevant for certain neurosurgical approaches. The MMA is assumed to run beneath the pterion, however, population studies have revealed variations in both pterional formation and the course of the MMA. We aimed to investigate whether there is a difference in the pterion/MMA relationship between left and right sides and/or known male and female subjects in a population sample of Romanian origin. 103 human adult skulls from the 'Fransisc I. Rainer' Human Osteological Collection were analysed. Pterion morphologies were recorded and a 'pterion centre point' was created. Four linear measurements (2 external and 2 internal) were taken from this point on each side to the: frontozygomatic suture, zygomatic arch, optic canal and lesser wing of the sphenoid. Transillumination of the skulls allowed visualisation of the MMA's course. The frequency of the MMA passing through a defined pterion region was recorded and the course of the MMA was mapped and described against the cranial bones.
