[Pericranial sinus. Definition, diagnosis, surgical treatment]
Abstract:
Pericranial sinus (Sinus pericranii - SP) is a rare pathology of the extra-intracranial cerebral venous system. However, SP is not just an additional transosseous canal that connects the extra- and intracranial venous systems. This "emissary vein" connects the intracranial sinus and the variceally extended thin-walled veins localized on the outer surface of the skull where blood flows fun in opposite directions. We present a literature review and two case reports of patients with pericranial sinus who underwent surgical treatment. We discuss the problems related to etiology, clinical signs, diagnosis, and surgical treatment of the anomaly.

Cranial Bones: Lateral View
The temporal bone forms the lower lateral side of the skull. The temporal bone is subdivided into several regions. The flattened upper portion is the squamous portion of the temporal bone. Below this area and projecting anteriorly is the zygomatic process of the temporal bone, which forms the posterior portion of the zygomatic arch. Posteriorly is the mastoid portion of the temporal bone. Projecting...
Cranial Bones: Superior and Posterior View
The frontal bone is the single bone that forms the forehead. At its anterior midline, between the eyebrows, there is a slight depression called the glabella. The frontal bone also forms the supraorbital margin of the orbit. Near the middle of this margin is the supraorbital foramen, the opening that provides passage for a sensory nerve to the forehead. The frontal bone is thickened just above each supraorbital margin,...
