Abstract Since its introduction over 2 decades ago, functional endoscopic sinus surgery (FESS) has revolutionized the surgical management of chronic sinusitis. Agger nasi cells (AN) and ethmoid bulla (EB) are derived from pneumatization of the first and second basal lamellae. Coronal image with arrowhead showing Agger Nasi air cell. 6. In patients with larger agger nasi cells comprising a significant portion of the frontal recess, this cell can be confused with the frontal sinus recess itself. 2. Gender: Female. Anatomic variations, such as deviation of the nasal septum, concha bullosa or paradoxical middle turbinate, ethmoidal bulla hypertrophic, agger nasi cell, lateral or medial bending of uncinate process (UP) and Haller cell are common and emphasized in routine evaluation of computed tomography (CT) images.

Agger nasi air cells are the most anterior ethmoidal air cells lying anterolateral and inferior to the f rontal recess and anterior and above the attachment of the middle turbinate. The frontal cells, located above the agger nasi cells, form the anterior wall of the frontal recess. Secondary middle turbinate (SMT) is a rare variation of the nasal cavity, which arises from the lateral nasal wall and usually projects superomedially, without obstructing the ostiomeatal unit .

Concha bullosa is the most commonly observed anatomical variation of the lateral nasal Agger nasi's location below the frontal sinus also defines the anterior limit of the frontal recess. Ethmoidal bulla dissection. The term frontal cells (frontoethmoidal cells) is currently used to describe a group of anterior ethmoidal cells that have been classified by Kuhn et al. Role of the agger nasi cell in chronic frontal sinusitis Agger nasi cells contribute to nasofrontal duct (NFD) obstruction and chronic frontal sinus disease. . Their location is anterior, lateral, and inferior to the frontal recess [ 1, 11 ]. The agger nasi cell can be located: 1) anterior to the middle turbinate origin or 2) directly superior to the most anterior middle turbinate insertion into the lateral nasal wall. The presence of frontal cells, type 1 to 4 should be looked for. Supra Agger Cell This is an anterior-lateral ethmoidal cell that sits superior to the agger nasi cell but does not pneumatize into the frontal sinus. The (*) highlight the hiatus semilunaris. Discover Cskm in Hajd-Bihar (Hungary). According to Van Alyea," the agger nasi cell is the most anterior and the most consistent of the ethmoid cells. There was a significant association between clinoid process pneu-matization and protrusion of internal carotid arteries and optic nerves into sphenoid sinus (P < 0.001).

There is septal Deviation to the left, a left-sided septal Fuspur (dotted white arrow), paradoxical curvature of the right middle turbinate (solid white . It usually borders the primary ostium or floor of the frontal sinus; thus, its size may directly influence the patency of the frontal recess and the anterior middle meatus. The frontal recess is behind the beak of the frontal bone between the lamina papyracea and superior portion of the middle turbinate. The infraorbital ethmoidal cells extend downward underneath the medial floor of orbit lying adjacent to and above the ostium of maxillary sinus and lateral to the infundibulum. Anatomical variants of the ethmoid bone have a special importance in several fields, especially in otolaryngology; a precise understanding of the complex anatomy and anatomic variations of the ethmoid bone is crucial for radiological diagnosis of paranasal pathology and for surgical work-up in order to avoid potential complications.
