Anatomical terminology] |
The ethmoidal infundibulum is a funnel-shapedanterior ethmoidal air cells,[4][2]: 612 and (usually[2]: 612, 690 ) the frontonasal duct (which drains the frontal sinus[1][4])[1][4][2]: 690 open into the ethmoidal infundibulum.[1] The ethmoidal infundibulum extends anterosuperiorly from its opening into the nasal cavity.[3][2]: 612
Anatomy
The ethmoidal infundibulum is bordered medially by the
uncinate process of the ethmoid bone, and laterally by the orbital plate of the ethmoid bone.[3]
The ethmoid infundibulum leads towards the
anterior ethmoidal cells open into the anterior part of the infundibulum.[6]
Variation
The frontonasal duct may or may not drain into the ethmoidal infundibulum - this is determined by the place of attachment of the
middle meatus.[6]
