Deformities of the nasal septum in human foetuses.

In a seris of 50 embryos and foetuses ranging from 20 mm to 190 mm in length two foetuses of 34 and 37 mm (48 to 50 days old) were found, that presented deformities of the septum of the cartilaginous nasal capsule, representing 4% of our material. The deformities consisted of curves of the nasal septum, located to both vomeronasal nerves. We therefore think that this study is interesting because it adds a new factor, the congenital one, to the etiology of deformities of the nasal septum.
