When the blow is more severe, it may fracture the nasal bones, dislocate them from the ascending process of the maxilla or fromthe nasal spine of the frontal bone, or separate the internasalsuture. These injuries not only drive the bridge of the noseinward and cause flattening or a saddle-like appearance, but the GUNSHOT AND OTHER FRACTURES OF THE FACIAL BONES. 185 dorsum of the organ is widened or perhaps deviated laterally.Combinations of injuries of the nasal bones, the cartilaginousdorsum, and of the septal structures give rise to much variationin the degree and character of the distortion of the nose. When the upper lateral cartilage is dislocated from the lowerborder of the nasal bone, there occurs a hollow in the dorsum ofthe nose at about the junction of the middle and the lower thirds.It should be reduced and supported. The quadrangular, car-tilage of the septum is luxated quite often from the perpendicu-lar plate of the ethmoid. The cartilage is shoved backward JUjLsal.

Thus the cartilagetakes an oblique position and obstructs both nostrils; one withits posterior, the other with its anterior portion. It may bedislocated from the maxillae. These dislocations should berecognized and reduced before swelling occurs. The fingerin the nares is a useful means of replacing the displacedstructures. Splints, plugs of gauze, a cork, or pins may be usedfor retention. Fracture of the nasal bones is more likely whenthe force comes from the side than otherwise; hence lateraldeviation as well as depression is common in nasal injuries. l86 WAR SURG
