Ethmoid infundibulum

The ethmoid infundibulum is a curved cleft of the ethmoid bone which leads into the anterior portion of the hiatus semilunaris. It is bordered medially by the uncinate process and laterally by the orbital plate of the ethmoid. The infundibulum is often continuous with the frontal recess into which the frontal sinus often opens. The anterior ethmoidal cells and maxillary ostia can also open into the infundibulum.
