Abstract
Fluid communication may be improved for an ethmoid sinus by installing a port or wick in the wall of the ethmoid sinus to provide a fluid passageway across the wall of the ethmoid sinus. Fluid communication for an ethmoid sinus may also be improved by inflating a balloon in a retrobullar space, remodeling the posterior wall of the ethmoid bulla to expand the transition area in the retrobullar space. In addition, a wall defining the retrobullar space may be pierced to provide a passageway for fluid communication.
