What's the difference between sphenoid and sphenoidal?
Sphenoid
Definition:
(a.) Wedge-shaped; as, a sphenoid crystal.
(a.) Of or pertaining to the sphenoid bone.
(n.) A wedge-shaped crystal bounded by four equal isosceles triangles. It is the hemihedral form of a square pyramid.
(n.) The sphenoid bone.
Example Sentences:

(4) The other structures or regions that were involved, in decreasing order of frequency, were the sphenoid sinus (26.7%), nasal fossa (21.8%), and ethmoid sinus (18.3%).
(5) A case of isolated sphenoidal tumor localization in a child without any endocrinological disorder and revealing an histiocytosis X is reported.
