Agger Nasi

Agger Nasi. The agger nasi (from agger meaning “mound or heap”) is a small ridge on the lateral side of the nasal cavity It is located midway at the anterior edge of the middle nasal concha directly above the atrium of the middle meatus.

Depending on the degree of pneumatization agger nasi cells can be bounded anteriorly by the frontal process of the maxilla anterolaterally by the nasal and lacrimal bones posterolaterally by the lamina papyracea superiorly by the frontal sinus inferolaterally by the uncinate process and posteriorly by the anterior ethmoid complex.

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 They are located within the lacrimal bone and therefore have as lateral relations the orbit the lacrimal sac and the nasolacrimal duct.

Role of the agger nasi cell in chronic frontal sinusitis

Agger nasi cells contribute to nasofrontal duct (NFD) obstruction and chronic frontal sinus disease To investigate this relationship we conducted a review of the surgical outcome and computed tomographic imaging in 26 patients with chronic frontal sinusitis Coronal and sagittal images were used t Author Joseph B Jacobs Barry A Shpizner Eugenie Brunner Richard A Lebowitz Roy A HollidayCited by Publish Year 1996.
