A shallow circular pit or depression, which resembles a small ulcer or punched out lesion can sometimes be seen on the anterior cartilaginous nasal septum. This is known as "Jacobson's Organ",...
The Normal Nasal Cycle
The state of vasodilatation [engorgement] and vasoconstriction of the erectile tissue of the inferior turbinate and of the nasal septal swell body normally alternates between the nasal cavities, i.e....
The Nasal Septal Swell Body
A discrete area of erectile tissue is present in the submucosa over the anterior cartilaginous nasal septum in some individuals. Vasodilatation of the septal swell body can be a cause of significant nasal...

In this next coronal section one can see the anterior end of the bony inferior turbinate. Courtesy of the visible human project.
Coronal Anatomy of the Nose and Paranasal Sinuses:...
This series of photographs demonstrates the anatomy of the nose and paranasal sinuses as seen from anterior to posterior. In this section one can see the anterior and of the bony nasal septum and the...

In this next slice one can now see the anterior ends of the middle turbinate and the anterior portion of the maxillary sinuses. Courtesy of the visible human project.
Steroid-Mixed Eardrop Dessicated Granules
This white salt-grain appearance of the external auditory canal finding is not uncommon after usage of steroid (fluocinolone acetonide)-mixed antibiotic eardrop. It is firmly attached to the epithelial...
Exostosis of the External Canal CT Scan
The dense ivory bone of exostoses arising from the anterior surface of the tympanic bone can be seen in this axial high-resolution CT scan.
Small Solitary Exostosis of the External Ear...
Exostoses of the bony ear canal are the result of localized areas of benign bony hypertrophy, which are thought to result from stimulation of the periosteum covering the medial surface of the tympanic...
