The olfactory fossae, or, recesses, of the cribriform plate are shallow depressions located within the ethmoid bone in the anterior cranial fossa. The floor is formed by the medial lamella of the cribriform plate and it is bordered laterally by the lateral lamellae. Its medial border is the perpendicular plate.

The depth of the olfactory fossa is determined by the length of the lateral lamellae of the cribriform plate. The Keros Classification is a means of classifying the depth of the olfactory fossa, as this area of thin bone is at risk during endoscopic nasal surgery.
