Quantitation of Neurosurgical Landmarks on Human Skulls In Relation To Sphenoidal Ridge: A Combined Anatomical and Radiological Study
Journal Title: Scholars Journal of Applied Medical Sciences - Year 2017, Vol 5, Issue 11
Abstract
Abstract: Sphenoid ridge, paraclinoid region and the surrounding structures are commonly involved in conditions such as meningiomas, carotid aneurysms and fistula. To provide accurate information the current study investigated the measurement of sphenoidal ridge in relation to surrounding structures in three independent parts. An anatomical study was on dry skull formalin fixed cranial cavity and computed tomographic scans of skulls. Hundred adult skulls of unknown sex, thirty adult formalin fixed human cadaveric heads and 100 annonymised CT images were examined for morphometry of sphenoid ridge. The length of the sphenoid ridge on right side was more as compared to left side on cadaveric and osteological specimen. Sphenoid ridge documented as lengthier on radiological examination as compared to osteological and cadaveric examination. The mean distance of crista alaris to foramen ovale on skulls, cadavers and CT images was found to be same on both sides. The anatomical orientation of sphenoid ridge, paraclinoid region and its distances from vital structures help in determining the safety and precision during surgeries in this area. Keywords:Lesser wing of sphenoid, Sphenoid ridge, Skull base, Cranium.
