Surgical dissection of the ethmoid labyrinth dates back to before 300 BC when Hippocrates removed polyps and parts of ethmoid cells with a sponge attached to strings.
Other findings include attenuation of the nasal septal and sinus trabeculae, and opacified ethmoid sinuses with bulging lateral walls.
As a result, the ethmoid air cells are rarely limited to the lateral ethmoid masses; they often extend into the turbinates, crista galli and the neighbouring frontal, maxillary, sphenoid and palate bones.
Similar to the study population overall, tumors with osteoblastoma-like features occurred most frequently in the frontal (59%) and ethmoid sinuses (44%).
1,2) These include: paranasal sinusitis, especially of the frontal sinuses (1-14) with the extension of infection from the sphenoid and ethmoid sinuses being relatively uncommon; (2) osteomy-elitis of the skull, which can be associated rarely with Pott's Puffy Tumor; (3,4,5) direct extension from the middle ear, the mastoid, or the orbit; trauma resulting in skull fracture; iatrogenic causes like craniotomy, skull traction for cervical fractures or scalp venous catheters in the pediatric population; (6) and hematological spread from a remote focus of infection.
A follow-up MRI scan in 2009 showed contrast-enhancing soft tissue abnormalities within both of the frontal sinuses and the left ethmoid sinus (Figures 1 and 2).
Specimens from right and left ethmoid sinus, as well as right maxillary sinus contents, were submitted.
One Year Results: Transantral balloon dilation of the ethmoid infundibulum" ENT Journal February 2010 Volume 89, Number 2.
Computed tomography (CT) of the sinuses showed right frontal and ethmoid sinusitis together with the right polypoid mass filling the lower posterior airway (figure 1, C).
The agger nasi cells (Latin for 'nasal mound') are the most anterior ethmoid cells.
Magnetic resonance imaging (MRI) demonstrated a round mass in the left nasal cavity, involving the sphenoid sinus and ethmoid sinus and compressing the left orbit and nasal septum, but without intracranial component (Figure 1).
1 FinESS dilates the ethmoid infundibulum, the main drainage pathway in the osteomeatal complex (OMC), with balloon dilation which preserves tissue, bone and ciliary function.
An unusual finding on the CT scan was what appeared to be an ostium or drainage pathway from the left ethmoid sinus into the superior portion of the left middle meatus (figure, A).
They are extramural cells (not confined within the ethmoid bone) and extend anteriorly into the lacrimal bone.
