Abstract
Through intensive study of the morphology of the humsn nose as well as that of various animals, the author confirmed the presence of two cartilagenous processes in the human nasal septum.
They are the processus sphenoidalis and the processus vomeris.
The latter is found exclusievely in the human nasal septum and has a positive relation with nasal septal deviation, height of the nose and angle of the cranial basis or angle of sella turaca.
In subjects with short processus vomeris the sella turcica in also small and often associated with severe septal deviation and rather high external nose.
The author concluded that the septal deviation which can be recognized by intranasal examination is the deviation within the cartilage and is produced by the active growth of the nasal septum, while the septal deviation within the perpendicular plate of the ethmoid is created passively due to development of the ethmoid cells on both sides.
The active deviation of the nasal septum is also related with metaplastic ossification and this gives a basis for the preservation of the external shape of the nose without being affected by senile atrophy.
Archaeological study has suggested that the processus vomeris first appeared in Homoneanderthal Man.
