Semilunar hiatus

The semilunar hiatus is a crescent-shaped/semicircular/[1]curved[2] slit[3]/groove[4] upon the lateral wall of the nasal cavity[5] at the middle nasal meatus.[3] It is bounded (sources differ) either inferiorly[4]/anteriorly[2][5] by the ethmoid bulla, anteriorly by the uncinate process of ethmoid bone.[5][2] It leads into the ethmoidal infundibulum;[6] it marks the medial limit of the ethmoidal infundibulum.[5]
