Anterior ethmoidal foramen

Other Terms: Foramen ethmoidale anterius, Foramen ethmoïdal antérieur


The anterior ethmoidal foramen is a small opening formed when the anterior ethmoidal notch on the superior margin of the ethmoid bone corresponds to a similar small notch in the frontal bone creating a small foramen in the sutural junction of the two bones. The foramen transmits the anterior ethmoidal nerve, a branch of the nasociliary nerve, into the anterior and middle ethmoidal sinuses and nasal cavity. Sometimes this small foramen forms entirely within the orbital plate of the ethmoid bone.
