“…In this study of 76 adult Indian skulls, the commonest type of pterion was the sphenoparietal type. Of more importance was the position of the pterion and its relationship to the anterior branch of the MMA [and its accompanying dural venous sinuses (Fishpool et al,2007)]. The center of the pterion was located at a mean of 26 mm behind and 11 mm above the posterolateral margin of the frontozygomatic suture.…”

Despite its clinical importance, the surface anatomy of the pterion is inconsistently reported. This study reappraises the surface marking of the pterion and its relationship to the middle meningeal artery (MMA). The position and morphology of the pterion were analyzed in the Frankfurt plane in 76 adult skulls and 50 adult cranial cone beam CT scans. Relationship to the anterior branch of the MMA was examined in the skulls. Measurement reproducibility was assessed in a 20% randomly selected sample. In the skulls, the majority of pteria were sphenoparietal (78%), followed by epipteric (16%) and frontotemporal (5%). The center of the pterion was a mean of 26 ± 4 mm behind and 11 ± 4 mm above the posterolateral margin of the frontozygomatic suture; measurements were reproducible and consistent between sides and genders. Distances from the frontozygomatic suture were slightly greater (29 and 16 mm, respectively) in cranial CTs. A one centimeter circle centered on the midpoint of the pterion overlapped the anterior branch of the MMA in 68% of skulls; the artery was a few millimeters posterior in the remainder. Mean skull thickness at the midpoint of the pterion was 4.4 mm compared to 1 mm at its thinnest point in the squamous temporal bone. In conclusion, in most adults, the pterion lies within a one centimeter diameter circle 2.6 cm behind and 1.3 cm above the posterolateral margin of the frontozygomatic suture (which is easily palpable in vivo). This region overlaps the anterior branch of the MMA in two-thirds of cases.

Skull base fractures comprise a relatively common finding among trauma patients. Before the widespread use of computed tomography (CT), these lesions used to be misdiagnosed. Currently, with improved imaging technology, diagnosis of skull base fractures is no longer cumbersome. On the other hand, cranial fractures involving the foramen spinosum are rarely described in the literature. In this present article, we report on a patient affected by head trauma, who suffered from a vault fracture towards the foramen spinosum and acute epidural hematoma (EH) due to middle meningeal artery injury. We further discuss the clinical consequences of foramen spinosum fracture. KEywoRds:Cranial epidural hematoma, Foramen spinosum, Middle meningeal artery, Skull base, Skull fracture ÖZKafa kaidesi kırıkları travma hastalarında nispeten sık görülen bir bulgudur. Bilgisayarlı tomografinin (BT) yaygın kullanımı öncesinde bu lezyonlara yanlış tanı konabiliyordu. Gelişmiş görüntüleme teknolojisiyle kafa kaidesi kırıklarına tanı koymak artık zor değildir. Öte yandan foramen spinosumu içeren kraniyal kırıklar literatürde nadiren tanımlanmıştır. Makalede kafa travması sonrasında foramen spinosuma doğru bir kafatası kırığı yaşayan ve orta meningeal arter yaralanması nedeniyle akut epidural hematom bulunan bir hasta sunuldu. Foramen spinosum kırığının klinik sonuçları üzerinde duruldu.

Background: The EDH occurs due to the accumulation of bleeding between the inner table of the skull and the outer layer of the dura mater. It is said to account for 1% -3% of all head injured patients and 9% of those who are comatose. The only life-saving treatment of choice is evacuation of EDH via craniotomy. Methods: This was a prospective observational study, where 40 patients were in follow-up for determining the outcomes of evacuation via craniotomy. Results: Majority of the patients were young and males. The main outcome of the evacuation was favorable (recovered), but certain unfavorable outcomes were also accounted like mortality. Conclusion: The pre-surgery clinical findings like consciousness of patient were an important indicator for EDH evacuation outcome. In most of the cases, the outcome was favorable with progressive recovery.
