The etiology of osseous deformities of the head, face, jaws and teeth . very marked and noticeable deformity. The dental arch iswell developed. Occasionally the turbinated bones are so situated that theair will deflect the vomer to one side or the other in such amanner that there will be a deformity at right angles, justbelow the inferior turbinated bone. This, however, cannot 266 ETIOLOGY OF OSSEOUS DEFORMITIES OF be located very near its place of attachment, for the reasonthat the vomer commences to enlarge or thickens as it reachesthe nasal spine, thus preventing the bend. The drawings of Zuckerkandl arc here given because theyillustrate the very points which I have made, and because theyare true to life. Fig. 77 shows the bone very unevenly developed. Thisis partly due to an excessively developed antrum upon theleft side and a correspondingly small one upon the right will be noticed that the turbinated bones and vomer are sodistributed that there is a uniformity of space throughout thecavity. The vomer even has deflected to the right in order. Fig. 78. to produce this harmony. It will be observed, however, thatthe bone is not broken, but simply bent, and that this bend isabout opposite the enlarged left inferior turbinated the face is very asymmetrical, the bones, which areintended for the purpose of warming the air, are nicelyarranged. The right cavity is considerably lower than theleft; the inferior turbinated has lengthened to has separated the lateral halves of the vomer, andthe space has filled in with bone. Fig. 78 is quite another case. Here we see the facial boneuniformly developed; the antra are comparatively uniform;the turbinated bones, however, are very unevenly developed. THE HEAD, FACE, JAWS AND TEETH 267 The bend and break in the vomer are about at a pointbetween the two turbinated bones, and exactly opposite theexcessively developed right inferior turbinated bone. It willbe observed that the bend is no
