Patients who required other nasal procedures like septoplasty, conchoplasty, and clearance of agger nasi
cells were included in the study.
The basal lamella of the ethmoid, the ethmoid strut, the anterior and posterior ethmoid cells, the medial wall of the ethmoid sinus, and the agger nasi
cell (if one had been present) were all removed (figure, B).
Twelve areas were specifically looked at for anatomical variations (Table 1) including; Type of skull base, Anterior ethmoid artery, Agger nasi
cells, Haller cells, asymmetry in anterior ethmoidal and onodi cells.
The agger nasi
cells (Latin for 'nasal mound') are the most anterior ethmoid cells.
is the second most common anatomical variant.
Computed tomography (CT) of the sinuses showed bilateral mucosal thickening in the frontal sinuses and the presence of a well-defined left-sided agger nasi
cell (figure, A).
The obstruction was caused by agger nasi
cells in 6 (43%), ethmoidal bulla or accessory cells in 4 (28.
The mass was opened with a microdebrider (figure, B), and it was identified as a hyperpneumatized agger nasi
cell (figure, C).
This finding is similar to that encountered in a study, in which DNS was the most common anatomical variant followed by agger nasi
cells seen in 44% and 40% cases of sinusitis respectively.
During surgery, we were able to visualize the natural ostium of her left agger nasi
The parameters used for correlation were- Deviated Nasal Septum, Inferior Turbinate Hypertrophy, Middle Turbinate abnormalities, Concha Bullosa, Agger Nasi
cells, Haller cells, Frontal recess, Infundibulum, Hiatus semilunaris, Uncinate process attachment, Intrasinus mucosal disease of Maxillary, Ethmoids, Frontal and Sphenoid detailed history, clinical examination and routine investigations were done for the patients.
Computed tomography (CT) of the sinuses showed opacification of both maxillary sinuses, a large and well-developed right agger nasi
cell, and a vertical insertion of the right middle turbinate (figure, A).
