The morphology of the sphenoid air sinus from childhood to early adulthood (1 to 25 years) utilizing 3D reconstructed images.
Various types of intrasinus (axessory or partial) septa of the sphenoidal air sinus (axial and midsagittal views).
warned, that surgery in this area should always be done under consideration of the sphenoid air sinus pneumatization, in order to avoid damage of the optic nerve and internal carotid artery.

The air sinus is often described as an asymmetrical pair (Anusha et al.), separated by a septum which commonly deviates to one side (Tan & Ong, 2007; Anusha et al.).
Only one study analyzed the sphenoid air sinus utilizing three dimensional reconstructed images (Li et al.).
