The suprabullar cells are a subset of variably present frontal recess cells located above the ethmoid bulla.

Terminology

They are nearly identical to frontal bullar cells. The distinguishing features with the latter are that the suprabullar cells are located entirely below the frontal ostium and do not extend into the frontal sinus.

When significantly pneumatized above the orbital roof, they are referred to as supraorbital cells.

Gross anatomy

The suprabullar cells are located above the ethmoid bulla. Their superior wall is the skull base. They contribute to form the posterior wall of the frontal recess.
