The practice of infraction toward the septum of the middle turbinate bone is widely known and is a method frequently resorted to in order to improve drainage of the paranasal sinuses of the anterior group, but one rarely hears of the process of deliberate displacement of the inferior concha.
It is often found that patients with septal deviation have enlarged turbinate bodies, in most cases the inferior on the concave side. This side is the larger and is rendered more or less normal by this "physiologic" hypertrophy. Otherwise, the natural respiratory functions of the nasal mucous membrane, i. e. warming, moistening and cleansing of the incoming air, would be continuously and adversely affected.
After correction of a septal deviation, the formerly narrow side is adequately distended, but frequently the originally large side has become too narrow. This condition is due to the above mentioned conchal hypertrophy. To save the patient
