A Study of Incidence of Emissary Sphenoidal Foramen in Dry Adult Human Skull Bones
نویسنده
چکیده
Emissary sphenoidal foramen is an inconstant foramen that gives passage to an emissary vein that connects pterygoid venous plexus with cavernous sinus, the importance of which lies in the fact that an infected thrombus from an extracranial source may reach cavernous sinus. The aim of the present study was to identify the incidence of emissary sphenoidal foramen. 100 dry adult human skulls were studied which were available from the Department of Anatomy at Vijayanagar Institute of Medical Sciences, Ballari, Karnataka, India. The emissary sphenoidal foramen was present in 60 skulls out of 100 skulls studied. Out of the 60(60%) skulls, emissary sphenoidal foramen was present bilaterally in 34(34%) skulls and in the remaining 26(26%) skulls it was unilateral, 15(15%) skulls showing on right side and 11(11%) skulls showing on left side. Anatomic variations of the emissary sphenoidal foramen could be explained by developmental reasons. The anatomical knowledge of emissary sphenoidal foramen and its incidence is not only important for anatomists but equally essential for an operating surgeon.

Morphometric Analysis of Accessory Sutural Bones Association With Parietal Emissary Foramina
Background: The sutural bones and fontanelle of the skull display unique morphological characters. Sutural bones are also called supernumerary bones or ossicles or Wormian bones (WB). These are irregular and develop from the independent ossification centers present along the cranial sutures. They appear on periosteal and endosteal surfaces of the skull with variations in size, number, shape, an...

The identification of mastoidal emissary veins is of importance in the neurosurgical practice to diagnose abnormal and normal structures. In the present study, the objectives were to estimate the prevalence rate of mastoidal emissary foramina in the temporal bones of the adult skull and to study their number and morphology. The present study included 48 adult human skulls which were obtained fr...

All 377 dry skulls were examined for the occurrence and morphometry of the foramen of Vesalius (FV) both in the middle cranial fossa and at the extracranial view of the skull base. There were 25.9% and 10.9% of FV found at the extracranial view of the skull base and in the middle cranial fossa, respectively. Total patent FV were 16.1% (11.9% unilaterally and 4.2% bilaterally). Most FV were foun...
متن کاملBilateral Duplication of the Sphenoidal Emissary Foramen: A Case Report with Implications for Surgeries using Transovale Cannulation
The sphenoidal emissary foramen (SEF) is an inconsistent foramen located in the middle cranial fossa. The SEF may transmit a sphenoidal emissary vein (of Vesalius), dural venous sinus, nervolulus sphenoidalis lateralis, or an accessory middle meningeal artery. Prior reports have noted SEF to exist unilaterally and bilaterally. Duplication of the SEF has also been documented to occur unilaterall...
