  • vein
  • emissary vein one passing through a foramen of the skull and draining blood from a cerebral sinus into a vessel outside the skull. (thefreedictionary.com)
  • anastomotic vein, superior a vein that interconnects the superficial middle cerebral vein and the superior sagittal sinus. (thefreedictionary.com)
  • These sinuses drain blood and cerebrospinal fluid from the brain and empty into the internal jugular vein. (wikipedia.org)
  • This is possible because of venous communication (via the ophthalmic veins) between the facial vein and the cavernous sinus. (wikipedia.org)
  • Thus, it is not the absence of venous valves but rather the existence of communications between the facial vein and cavernous sinus and the direction of blood flow that is important in the spread of infection from the face. (wikipedia.org)
  • A type of emissary vein goes through the sphenoidal emissary foramen inferior to the zygomatic arch with the cavernous sinus on the inside of the skull. (wikipedia.org)
  • bone
  • Between the eyes and beneath the frontal bone is the ethmoid bone, which contains the group of small ethmoidal sinuses. (reference.com)
  • nose
  • Under the eyes on either side of the nose are the maxillary bones, which contain the maxillary sinuses. (reference.com)
  • Superior
  • Thinning or dehiscence of the superior semicircular canal may occur on the middle cranial fossa floor or adjacent to the superior petrosal sinus (SPS). (bmj.com)
  • optic
  • In addition, it is possible that inflammation of the cavernous sinus will result in compression of the optic chiasm (resulting in vision problems) and/or the pituitary gland. (wikipedia.org)
  • surgical
  • Gradual dural sinus occlusion of the type that is induced by slow growing tumors, such as a meningioma, is much better tolerated than acute occlusion secondary to either trauma or surgical intervention . (springer.com)
  • include
  • Conventional methods of stabilizing fragments in cranial impression fracture include the use of threads, wires, plates, etc. (springer.com)
  • Symptoms include pain at the forehead or ear, pus draining from the ear or sinuses, tenderness overlying the infectious site, fever, neck stiffness, and in rare cases focal seizures. (wikipedia.org)
  • Effects
  • It is intended mainly for cleaning the cranial sinuses but has many other effects including curing anemia, according to the Gherand Samhita and other sources. (wikipedia.org)
  • skull
  • A skull fracture is a break in one or more of the eight bones that form the cranial portion of the skull, usually occurring as a result of blunt force trauma. (wikipedia.org)
  • The human skull is anatomically divided into two parts: the neurocranium, formed by eight cranial bones that houses and protect the brain-and the facial skeleton (viscerocranium) composed of fourteen bones, not including the three ossicles of the inner ear. (wikipedia.org)
  • This area of the cranial floor is weakened further by the presence of multiple foramina as a result this section is at higher risk for basilar skull fractures to occur. (wikipedia.org)
  • However, in contrast to later cetaceans, the tympanic bone makes contact with the periotic bone which is firmly attached to the skull leaving no space for isolating air sinuses, effectively preventing directional hearing in water. (wikipedia.org)
  • bones
  • The eight cranial bones are separated by sutures : one frontal bone, two parietal bones, two temporal bones, one occipital bone, one sphenoid bone, and one ethmoid bone. (wikipedia.org)
  • Leontiasis ossea, also known as leontiasis, lion face or Lion Face Syndrome, is a rare medical condition, characterized by an overgrowth of the facial and cranial bones. (wikipedia.org)
  • In the somewhat less common form of this rare disease the overgrowth of bone affects all the cranial bones as well as those of the face, the senses being lost one by one and death finally resulting from cerebral pressure. (wikipedia.org)
  • common
  • Although relatively common intra-cranially accounting for 8% of all intra-cranial tumors, they seldom arise primarily within the infra-temporal fossa. (eurorad.org)
  • This location is one of the least common anatomical sites for extra-cranial schwannommas whereas the pharyngeal area is the most frequent one (1). (eurorad.org)
  • area
  • The area of the right lobe is defined caudal to the duodenal flexure, ventral to the right kidney and cranial to the colon. (vin.com)
  • This type of twinning is defined as having limited surface area involvement, with either intact crania or cranial defects. (wikipedia.org)
  • origin
  • The left adrenal is ventrolateral to the aorta between the origin of the cranial mesenteric artery and the left renal artery. (vin.com)
  • Head
  • To avoid being picked up by the head or neck, a horned lizard ducks or elevates its head and orients its cranial horns straight up, or back. (wikipedia.org)
