In the plastic correction of lateral deviation of the nasal axis, which is almost invariably a traumatic condition, it is required to move the nose back to the midline. When the deviation is slight, section through the nasofrontal process by the usual intranasal incision will usually permit replacement to the midline, involving only a slight overriding of the frontal process of the superior maxillary bone. In cases of marked deflection, it becomes necessary to remove a triangular wedge of bone from the broad concave side in order to create space for shifting the narrow convex side medially without marked overriding of bone.
After preliminary antisepsis and the production of anesthesia, a curved doubleedged knife is entered at the lateral angle of the apertura piriformis (on the broad concave side of the nose) and directed upward over the outer surface of the nasal bone toward the inner canthus. Care is
