AIM This study was designed to determine the anatomic position of the asterion and the relationship between the asterion and the transverse sigmoid sinus junction (TSSJ) in a Chinese cohort. MATERIAL AND METHODS Venous computed tomography (CT) angiography was performed in 32 patients to simultaneously obtain 3D-CT volume rendering images of the cranial bone and the dural sinus. The relationsh...

The accuracy of surgical drilling guides was assessed for placement of zygoma implants. Six zygoma fixtures of length 45 mm (Nobel Biocare, Göteborg, Sweden) were placed in three formalin-fixed human cadavers using surgical drilling guides. The fabrication of these custom-made drilling guides was based on three-dimensional computerized tomography (3D-CT) data for the maxillary-zygomatic complex...

The tritheledontid Riograndia guaibensis was the first cynodont described for the "Caturrita Formation" fauna from the Late Triassic of southern Brazil (Santa Maria 2 Sequence). The type materials did not preserve anatomical information regarding braincase, occiput, basicranium, zygomatic arch, postdentary bones and craniomandibular joint. Here new materials are described and supply the missing...

BACKGROUND/AIM A longer period of vessel occlusion reduces the coefficient of variation of the infarct lesion size ['infarct variation coefficient' (IVC)] due to a gradual expansion of the lesion within a limited territory defined by the vascular anatomy, but it increases the mortality rate. A crucial issue in the induction of experimental focal cerebral ischemia has been to achieve a low IVC v...

We aim to describe the technical details of the transzygomatic approach to intracranial surgery. The incision begins at the level of the inferior border of the zygomatic arch, anterior to the tragus, and extends towards the contralateral pupillary line. A subgaleal and interfascial dissection is performed. Then, the zygomatic arch is vertically sectioned twice and mobilized downwards, together ...
