Depends on several factors

It is quite difficult to answer the question without seeing a photo. Lengthening the nose can be done several ways depending on what the problem is. If someone needs a radix graft, this is determined by the profile view as well as width of the face, eye width, etc. See a revision rhinoplasty specialist to give you the answer to the multifaceted issues involved.

You asked a very good question about nasal aesthetics and the impact of grafting on different views. It is true that a washed out nasal bridge can give the sense that your eyes are farther apart. Conversely, adding height to the bridge can theoretically give the sense that eyes are drawn closer together.

But (and this a big but here), you must think about where you are coming from. If your bridge was taken down too low during a previous surgery and you are considering adding back some natural height and length to balance your nose, then the impact of a radix graft on the appearance of your eye width will be minimal. On the other hand, improving a washed out appearance of your bridge would have the effect of creating more nasal narrowing and refinement from the frontal view. And, this is hopefully what you're trying to accomplish.

Best of luck with your revision.
