Retrobullar recess

Dr Henry Knipe and Dr Maxime St-Amant et al.

The retrobullar recess is a small potential opening (cleft) rather than an actual air cell located superior and posterior to the ethmoid bulla, separating it from the skull base and basal lamella. The ethmoid bulla usually opens posteriorly in the retrobullar recess.
