Extensive pneumatisation of the Sphenoid Bone - anatomical investigation of the recesses of the Sphenoid sinuses and their clinical importance.
Folia morphologica, 2020Co-Authors: J Jaworek-troć, J A Walocha, M Loukas, R S Tubbs, J Iwanaga, J Zawiliński, K Brzegowy, J J Zarzecki, A Curlej-wądrzyk, E KucharskaAbstract:There is a great variance between the extent of pneumatisation of the Sphenoid sinuses that can reach beyond the body of the Sphenoid Bone. The purpose of this study was to find the frequency prevalence of the recesses of the Sphenoid sinuses in Polish adult population. 296 computed tomography (CT) scans of patients who did not present any pathology in the Sphenoid sinuses were evaluated in this retrospective analysis. Spiral CT scanner - Siemens Somatom Sensation 16 - was used to glean the medical images. Standard procedure applied in the option Siemens CARE Dose 4D. No contrast medium was administered. In the majority of the patients - 93.92%, the pneumatisation of the Sphenoid sinuses expanded beyond the body of the Sphenoid Bone, hence there were recesses of the sinuses present. The most common variant was the prevalence of two recesses - 12.84% of the cases. The frequency prevalence of all the 17 recesses was only 0.34%. Amongst the uneven recesses present, the Sphenoidal rostrum's recess (61.15% of the patients) and the inferior clinoid recess (56.42%) were the most common. Amongst the even recesses present, the lateral recess was prevalent in the majority (65.88%), whereas the posterior clinoid process' recess was the least common (9.8%). Presence of the recesses might facilitate access to the cranial fossae, hence comprehensive evaluation of the Sphenoid sinuses is of immense importance in order to avoid unnecessary drills through the hard Bone, that could potentially damage the nearby neurovascular structures.

Fetal Sphenoid Bone: imaging using three‐dimensional ultrasound and computed tomography
Ultrasound in Obstetrics & Gynecology, 2008Co-Authors: J.-m. Levaillant, M. MabilleAbstract:The Sphenoid Bone is a medial Bone that contributes to the formation of the cranial, nasal and orbital cavities. It is composed of three parts, namely the body and greater and lesser wings. The body, which is more or less cuboid, is located at the base of the occipital and ethmoid Bones. The lesser wings define the contour of the optical duct, and the superior smooth face of the lesser wings is in contact with the frontal Bone and contributes to the formation of the anterior cranial floor and orbit. The greater wings contribute to the medial cranial floor 1 . Imaging the Sphenoid Bone in the human fetus can be achieved partially using two-dimensional (2D) ultrasound. In a cross-sectional study of 386 normal singleton fetuses at 14–40 weeks’ gestation, Deganiet al. 2 used it to measure the largest diameter of the Sphenoid Bone in an axial plane of the fetal brain, showing the four cranial fossae divided by the greater wings of the Sphenoid anteriorly and the otic cartilage posteriorly. They reported significant positive linear relationships between Sphenoid wing length and gestational age, femur length and biparietal diameter. They also reported that the Sphenoid wing lengths of two microcephalic fetuses were less than 2 SD below the mean, and that the anterior cranial angles were more than 2 SD above the mean in two brachycephalic fetuses 2 . However, the position and complexity of the shape of the Sphenoid Bone are

The 360 photography: a new anatomical insight of the Sphenoid Bone. Interest for anatomy teaching and skull base surgery
Surgical and Radiologic Anatomy, 2017Co-Authors: Timothée Jacquesson, Patrick Mertens, Moncef Berhouma, Emmanuel Jouanneau, Emile SimonAbstract:Skull base architecture is tough to understand because of its 3D complex shape and its numerous foramen , reliefs or joints. It is especially true for the Sphenoid Bone whom central location hinged with most of skull base components is unique. Recently, technological progress has led to develop new pedagogical tools. This way, we bought a new real-time three-dimensional insight of the Sphenoid Bone that could be useful for the teacher, the student and the surgeon. High-definition photography was taken all around an isolated dry skull base Bone prepared with Beauchêne’s technique. Pictures were then computed to provide an overview with rotation and magnification on demand. From anterior, posterior, lateral or oblique views and from in out looks, anatomical landmarks and subtleties were described step by step. Thus, the sella turcica , the optic canal, the superior orbital fissure, the Sphenoid sinus, the vidian canal, pterygoid plates and all foramen were clearly placed relative to the others at each face of the Sphenoid Bone. In addition to be the first report of the 360 Photography tool, perspectives are promising as the development of a real-time interactive tridimensional space featuring the Sphenoid Bone. It allows to turn around the Sphenoid Bone and to better understand its own special shape, numerous foramen , neurovascular contents and anatomical relationships. This new technological tool may further apply for surgical planning and mostly for strengthening a basic anatomical knowledge firstly introduced.
