Suprabullar recess

The suprabullar recess is a potential opening (cleft) between the bulla lamella and skull base located along the posterior margin of the frontal recess with which it may communicate directly. It is present when the bulla lamella is incomplete superiorly.


The term ​sinus lateralis is sometimes used in the literature to refer to both the suprabullar and retrobullar recesses.
