Is There a Relationship Between Optic Canal, Foramen Rotundum, and Vidian Canal?

Journal of Craniofacial Surgery, 2015
In this retrospective study, we investigated the relationship between paranasal sinus, optic canal, foramen rotundum, and vidian canal measurements.Computed tomographic (CT) images of 320 adult subjects and 640 sides (right and left) were used. Paranasal sinus dimensions, optic canal (OC), foramen rotundum (FR), vidian canal (VC), bilateral FR (FRFR ...

Endoscopic Anatomical Study of the Skull Base with Poor Pneumatization: A Quantitative Analysis Based on Cadaveric Specimens [PDF]

Brain Sciences
Background: The endoscopic endonasal approach (EEA) has been widely applied in the surgical treatment of skull base tumors. However, poor pneumatization of the skull base—such as inadequate sphenoid sinus pneumatization and dense clival bone—can severely
