Roof Of Ethmoid Sinus Radiology

The anterior ethmoidal air cells drain to the hiatus semilunaris and middle meatus via the ethmoid bulla which forms parts of the ostiomeatal complex.

Roof of ethmoid sinus radiology.

Objective we evaluated the extent of asymmetry evident in paranasal sinus computed tomography ct scans of turkish patients without sinusitis in the ethmoid roof. An ethmoid mucocele is a form of a paranasal sinus mucocele involving the ethmoid air cells. It is a very dangerous area with respect to surgical dissection 3 11. The ethmoid roof is primarily formed by the fovea or fossa ethmoidalis an extension of the orbital plate of the frontal bone 4 6 10.

The anterior middle and posterior ethmoidal air cells. The lateral lamella joins the cribriform plate to the fovea ethmoidalis. This page provides a gallery of images that presents the anatomical structures found on orbit ct. Ethmoid mucoceles are considered the second most commonest in location 2.

Our data contribute to the body of knowledge on the subject. Depending on its anterior and or posterior location they can also include nasoethmoid and sphenoethmoid mucoceles. The middle group are now incorporated into the anterior group. The very thin horizontal cribriform plate lamina cribrosa of the ethmoid bone is bounded laterally by the vertical lateral lamella.

The ethmoid labyrinth is covered by the fovea ethmoidalis of the frontal bone and separates the ethmoidal cells from the anterior cranial fossa.
