Ethmoid

(3) 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%).
(4) The richly vascularized gland is supplied on its medial surface by large branches of the supraorbital and ethmoidal arteries.

(8) The occurrence of an ethmoid exposure in the orbit of Indri suggests that this trait is not a simple function of orbital size and convergence.
(9) The cerebrospinal rhinorrhea recurred four and six months after operation in the two patients with fistulas to the posterior ethmoids probably due to surgical, technical problems in one patient and to less support by the plaster of Paris, when the fistulas end in this region.

Mesethmoid
Definition:
(a.) Of or pertaining to the middle of the ethmoid region or ethmoid bone.
