A frontal flap, as outlined in the same illustration, is now cut from the forehead, leaving a pedicle as shown, and containing a section of bone at its median line. This is rotated downward and into place, and sutured along the same margin to which the genian flap is fixed, as shown in [Fig. 378].
When the frontal and genian flaps have become well united, the latter’s pedicle is cut when the freshened lateral margin of the frontal flap is sutured into place.
A subseptum is now made or deemed necessary by this surgeon.
At a later period the pedicle of the frontal flap is cut, and fixed by suture and some cutting, to reduce the resultant prominence thereof.

Helferich Method.
Preidesberger Method.—This author cuts away the skin surrounding the arch of the old nose, and turns this flap downward to form the lining to the flap made from the forehead made in the same manner as Helferich.
The bone section is made in the median line, and is one centimeter wide and four long.
