I ACKNOWLEDGE with a deep sense of my professional obligations the very close relationship that exists between the science of laryngology and that of orthodontia, and that from a practical, clinical point of view the sincere cooperation of these two great groups is essential to the best interests of the patient. I note with satisfaction that excellent results are now being secured in the management of certain cases where the value of cooperative effort is recognized. Deformities of the nose may be grouped under two main divisions: congenital and acquired. The physical qualities of each may be due t,o distortion, to deficiency or superabundance of the material constituting the structure of the nose Congenital deformities of the nose are practically always accompanied by abnormalities in the development of the bones and soft tissues of t,he face and mouth. In some instances (as in wolf-nose) the skull itself is seriously involved. The treatment of severe congenital deformities is sometimes a. difficult problem; usually it is best solved through the concerted efforts of the orthodontist and the rhinologist. By operative measures and by the use of molding appliances, we try to alter the misdirected forces of Nature and guide them along lines that will eventually result in the construction of a normal organ. In the correction of congenital deformities during early childhood, it is seldom necessary to resort to the transplantation of bone or cartilage. In these cases we confine our efforts to transposition and molding of the actively growing tissues that are already there. It is now conceded by all who accept the laws of biology and physiology as being fundamental, that bone or cartilage from the patient’s own body should be used as a transplant in any part of the body where tissues having the quality of rigidity or resiliency have been destroyed and need to be replaced in order to restore the part to its anatomic and physiologic perfection. The use of foreign materials of any kind whatsoever, as implants into the living tissues, should be condemned unconditionally. By foreign substances I mean any material that is incapable of being nourished by the blood and being incorporated as a part of the living body. If it can possibly be avoided, one should never concede to the wishes of a patient, who prefers to have a foreign body introduced into his tissues rather than submit to the slight additional inconvenience attendant upon the transference of tissue from one part of his body to another. It. is unnecessary for me to say that excellent primary results in the correction of certain nasal deformities may be secured by the implantation of a
