Superior Nasal Concha

The small, delicate seashell shaped bone located above the two other turbinates, projecting toward the perpendicular plate from the ethmoid bone is the superior concha or superior turbinate ^[1]. It is considered a part of the ethmoid bone.

Located underneath and lateral to this bone is the superior meatus ^[2], a narrow oblique fissure where the posterior ethmoidal cells open ^[4]. The sphenoethmoidal recess, the narrow opening of the sphenoidal sinus, is situated directly above the superior concha ^[3]. The superior meatus and the sphenoethmoidal recess are separated from each other by this concha ^[5].
