Curvature Nose

septum, suffers and tip

NOSE, CURVATURE OF.A deformity which is due principally to a bending of the dividing wall of the nose. Slight curvatures are so frequent that they may almost be called the rule ; and usually they cause no dis turbances. More marked degrees of curvature prevent the free passage of air, and also change the external shape of the organ, so that it is either curved in its entirety or suffers a double deflection (the root being turned to the left and the tip to the right, or vice versa).

Curvature of the nose may result from blows, knocks, or falls ; or it may be due to a disturbance of the growth of the facial bones. Slight injuries to the nose, leading only to insignificant haemorrhages, may fracture the delicate cartilage of the septum, or displace it from its groove. If medical aid be procured at once, it is possible, by packing the nose, to replace the deflected part of the septum without much trouble. It may, however, heal in an incorrect position, in which case special treatment may be required later. A child which, after an injury to the nose, breathes with difficulty

through that organ, or suffers a change in the sound of its voice, should be carefully examined for possible nasal injuries and defects.

If the septum of the nose be bent in consequence of defective growth, it is mostly due to an arch-like curvature of the palate. The so-called " aquiline " nose (see Fig. 296) is not caused by the deflection of the septum, but by projection of the nasal bones ; and it does not necessarily cause disturbances of breathing. Depression of the septum in consequence of ulcerative processes (syphilis) gives rise to a so-called " saddle-nose." The bridge of the nose is broad and fallen in, the tip is raised, and the nostrils face slightly forward and upward (see Fig. 297).
