In practically all rhinoplasties it is necessary to reconstruct the tip of the nose so that it will appear well proportioned and natural. In attempting to establish an ideal procedure for such a difficult problem, it was necessary to consider the advantages and disadvantages of a great number of prevalent methods as described, observed, discussed, and practiced.
Over many years of constant application and modification of various phases of existing acceptable methods, certain significant observations were made. In the first place, when the usual intercartilaginous and transfixion incisions were made, there developed certain anatomical landmarks which were most helpful and practical guides in producing a pleasing and natural tip. These landmarks are distinctive "red areas" and inverted "V" slits and are always present after the intercartilaginous and transfixion incisions are made. They are also found in secondary cases. For the sake of simplicity it seems logical to designate these landmarks
