The skin is held back, as shown in [Fig. 474], and the same mode of procedure is followed as that just given.

Lateral Nasal Incision (Author’s method).
The operator will have some difficulty to reach the opposite anterior border of bone elevation, especially if the incision has not been made long enough. This should be done. At no time should the assistant employ too much force in retracting the anterior flap to better expose the field of operation; it is certain to cause gangrene of the skin.
To overcome a long scar line, and to facilitate the cutting away of the bone, the author had a special set of chisels made with curved cutting blades, one angular and the other straight-edged. There are two each for working from the right and left sides. The striking point lies midway between the blade and the end of the handle.
They are shown in [Figs. 475 and 476].
