It is readily diagnosed ; there is usually much external deformity, the nostril on the affected side is occluded (for it is usually one-sided, though it may be double), and there is a corresponding concavity on the unaffected side. If the subject is directed to obstruct each of the nasal openings separately, and to blow, a free current of air will pour out of the cavity on the unaffected side, while a very thin current of air or none at all ap- pears at the occluded side.

Asa result, which illustrates the effect of stenosis on the development of the bones, there was observed a deviation of the intermaxillary bone and the sagittal suture towards the occluded side, a shortening of the nasal bone, frontal bone, horizontal plate of the palate bone, flattening of the alveolar process, and a reduction of the distance between the auditory canal and the alveolar process, as well as between the zygomatic arch and the supra-orbital border.
