Cavernous sinus contents (mnemonic)
Updates to Article Attributes
Body
was changed:
The structures inside and beside the cavernous sinus and their relative position can be recalled with the following mnemonic:
- O TOM CAT
Consider a coronal view of the cavernous sinus.
'O TOM' are the first letters of components of the lateral wall of cavernous sinus considered vertically, from the top to the bottom. CA are the first letters of the structures located within the sinus. CA continues virtually at the level of the T of 'O TOM'. So that the T represents the point of conjunction of the two words. See belowFigure 1 for further illustration:

O TOM CAT
Remember two things:
- the mandibular branch of the trigeminal nerve is not associated with the cavernous sinus since it has descended vertically through the foramen ovale underneath the trigeminal ganglion (Gasser ganglion), which is anatomically posteriorly to the cavernous sinus
- the maxillary branch of the trigeminal nerve is external but immediately adjacent to the lateral wall of the cavernous sinus, which becomes important in the differential diagnosis of lesions of the cavernous sinus - lesions of this nerve tends to distort the sinus rather than occupy it
