In traditional Messerklinger FESS technique, the sphenoid sinus is entered through the posterior ethmoid and not through its natural drainage via its ostium in the spheno-ethmoidal recess.
The sphenoid sinus can also be approached through the superior meatus or the spheno-ethmoid recess. As mentioned before, it is better to drain the sphenoid sinus endonasally through its natural ostium and therefore follow the natural pathway of its mucociliary drainage pathway.
