Jerry,
We do use fillers for the nose on occasion, but you have to have a specific deformity for them to work. If your hump is small and you have a low point superior or inferior to the hump then you can use filler to build up the nose around the hump and camouflage the hump. If the hump is large or the areas surrounding the hump are not deficient however then this is not possible. There is not a permanent filler I would recommend for the nose. Especially if you are considering rhinoplasty. The temporary fillers last at least 12 months in the nose however, are easy to do in the right person and are relatively low cost.
