Sphenoidal fontanelles

The sphenoidal or anterolateral fontanelles are paired bilateral soft membranous gaps (fontanelles) at the junction of the coronal, sphenofrontal, sphenoparietal, sphenosquamosal, and squamosal sutures. Each sphenoidal fontanelle persists until approximately six months after birth, after which it is known as the pterion.
