The median frontal flap described by Kazanjian, a horizontal or slightly oblique frontal flap and the scalp flap described by Converse are discussed. It is shown that each method can be used for specific indications. The choice of method by the less experienced is therefore facilitated. A. The median frontal flap is especially indicated for the grosser defects of the back and the lateral parts of the nose. B. The horizontal or slightly oblique frontal flap is especially indicated for subtotal or total defects of the nasal alae or tip of the older patient, who can not undergo repeated surgery or prolonged hospitalisation. C. The frontal scalp flap is especially indicated for the grosser subtotal or total defects of the external nose. - The fronto-temporal flap, described by Schmid, and the "Island-flap" belong to flaps, who need more experience on the field of plastic surgery. The latter is described in his different variations and it is shown the advantage of "one time" equalization of defects by using this technique. The "bilobed flap" too allowes the "one time" equalization and is suitable for the surgery of defects in the region of the tip of the nose.
