Upon birth, the subject has only maxillary sinus and 2 or 3 ethmoidal cells.
The pneumatization of the middle turbinate occurs as an extension of the ethmoidal cells, which extends through the superior meatus or through the frontal recess.
Face sinuses tomography identified a total maxillary veiling to the left and some posterior ethmoidal cells.
We found in all cases that the artery coursed freely through the ethmoidal cells, positioned far from the ethmoidal roof.
They are extramural ethmoidal cells that pneumatize inferiorly to the orbital floor, extending from the ethmoid labyrinth, below the ethmoid bulla, towards the interior of the maxillary sinus Figure 10.
Access was changed to the infranasal or sublabial approaches,which avoided having to enter the ethmoidal cells, thus reducing the risk of infection.
Anatomical variants arising from ethmoidal cells development process are the most common, frequently associated with inflammatory processes and responsible for most of paranasal sinuses revision surgeries.
Computerized Tomography in coronal cutoff with an arrow indicating the concealing of the front and rear ethmoidal cells and of the left maxillary sinus.
For instance, in the frontal recess approach,the presence of some ethmoidal cells may change the anatomy and, consequently, the surgical access such as frontal cell, supraorbital cell, agger nasi cell and ethmoidal bulla which should be described.
Its most anterior portion harbors other relevant structures, such as the agger nasi ethmoidal cells, the lacrimal sac and the nasolacrimal duct NLD.
Computed tomography CT of the face and neck with venous contrast showed an expansive formation with a cystic, septated appearance, measuring 5.8 x 4.8 x 4.0 cm, on the right parotid gland Figure 3, which was indistinguishable from the lesion. The CT also revealed enlarged lymph nodes located in the right submandibular chain and bilaterally in the internal jugular chains,in addition to which the maxillary sinus and the ethmoidal cells on the right side were sealed.
The CT revealed inflammatory sinusopaty with concealing of the maxillary sinus, ethmoidal cells and esphenoidal sinus in the left nasal cavity Pictures 1 and 2.
The computed tomography of the facial sinuses revealed a total left maxillary veiling with affection of posterior ethmoidal cells Figure 2 and 3.
Computerized Tomography in axial cutoff with an arrow indicating the concealing of the front and rear ethmoidal cells and of the left esphenoidal sinus.
The roof of the ethmoidal labyrinth is formed by the fovea ethmoidalis, an extension of the frontal bone orbital plate,primarily separating the ethmoidal cells from the anterior cranial fossa.
The patient underwent routine examination. Skull CT scans were ordered because of the symptoms he manifested, anda tumor with soft-tissue density measuring 19 x 20 x 30 mm was seen in the left posterior ethmoidal cells, in addition to erosion of the lamina papyracea Figure 1.
In order to avoid this complication, it is necessary that the surgeon has the knowledge of the complex anatomy involving the anterior skull base,including the ethmoid fovea, the ethmoidal cells, the lateral lamella and the route of the anterior ethmoid artery which can be demonstrated by tomography.
Thus, preoperative recognition of supraorbitary pneumatization in CT is valuable, as it provides an alert that the anterior ethmoidal artery canal is far from the ethmoidal roof, andcourses freely within the ethmoidal cells; this increases significantly the risk of injury of the anterior ethmoidal artery during a surgical procedure.
This is typically the first ethmoidal cell seen in the coronal plan at the antero-posterior direction and is typically confluent with the uncinated process 12.
Of those patients with abnormalities on computed tomography scans, 100% presented maxillary sinus abnormalities, 94% presented ethmoidal cell abnormalities, 39% presented frontal sinus abnormalities, and 26% presented sphenoid sinus abnormalities.
In many a case, the anterior most ethmoidal cell, the Agger nasi, will be exposed during removal of the most superior and medial portion of the lacrimal fossa bone Figure 6.
Frontal bullar cell is the ethmoidal cell located above the ethmoid bulla that pneumatizes along the skull base towards the frontal sinus, sometimes causing convexity in its floor Figure 12.
