RABBIT SNOUT GROWTH AFTER DISLOCATION OF NASAL SEPTUM.

Introduction and Purpose Any interference which will affect growth centers of bones will alter the orderly progression of development and will result in faulty growth. The degree of the subsequent deformity will depend not only upon the type, intensity, extent, and chronology of the noxious agent, but also upon the site and its particular susceptibility and growth activity. Thus, effects of trauma to different sites of growth of bones may be quite variable. It has been demonstrated that areas of cartilaginous growth are more susceptible to trauma than those of sutural growth. 1 The relationship of trauma to development of the nose and related structures is of clinical importance. In a previous experiment on young growing rabbits, varying amounts were extirpated of the septovomeral joint, the cartilaginous nasal septum, vomer, and maxillary process of the premaxilla. 2 Severe alterations of growth were noted. The snout was shorter, broader, and angulated
