This accomplished, the wound is temporarily dressed. The cartilage is then fashioned to suit the required size and shape.
It is thinned down on its lower surface to about three millimeters in diameter. This thickness is maintained to a length of two and a half centimeters, the part being intended for the subseptum.
A notch is made on the upper surface at this distance from the end, which marks the point at which it must be eventually bent to form the point of the nose. This notch is cut to two thirds of the entire thickness.
The required length, that of the nasal line and its added septal length, is preserved.
The cartilage being prepared is now ready for the insertion under the frontal periosteum at the site already marked.
For this purpose a vertical incision one and a half centimeters, extending down to the bone, is made, as shown in [Fig. 391].

The periosteum is peeled away from the bone with the dull or rounded handle of a knife.
