The roof of the ethmoid bone is formed by the fovea ethmoidalis laterally and the cribriform plate medially.
9) In 1962, Keros studied 450 skulls and described 3 types of olfactory fossas which are formed by cribriform plate and the fovea ethmoidalis.
Four patients had their leaks identified in the area of fovea Ethmoidalis (Anterior Ethmoid cells) and one patient had a large defect in the sphenoid sinus following trans sphenoid resection of pituitary adenoma.
The medial division was attached superiorly to the middle concha, and the lateral division was attached to both the fovea ethmoidalis and the lamina papyracea.
3) The most common location of the defect is the region of the fovea ethmoidalis and posterior wall of frontal sinus followed by the cribriform plate of ethmoid and the sphenoid sinus.
The tissue removed included the root of the superior middle turbinate and the anterior skull base mucosa adjacent to the superior-most anterior ethmoid cell next to the fovea ethmoidalis.
Skull Base Configuration: The roof of the ethmoid bone is formed by the fovea ethmoidalis laterally and the cribriform plate medially.
One of the characteristic radiographic findings of olfactory neuroblastoma is a dumbbell-shaped mass that extends across the cribriform plate; erosion of the cribriform plate, lamina papyracea, and/or fovea ethmoidalis may also be seen.
The ethmoid sinuses are divided into groups of cells by bony basal lamellae that extend laterally to the laminae papyracea and superiorly to the fovea ethmoidalis.
The multiple defects involved the anterior and posterior walls of the frontal sinuses, the fovea ethmoidalis bilaterally, the cribriform plate, the far-right lateral floor of the sphenoid sinus, and both lateral sphenoid walls.
