Filler Now, Small Revision Rhinoplasty Later for Nose Dent?

A tissue filler can be used as a temporary solution while waiting for further surgery. The filler should be resolved before commencing the Rhinoplasty.

Injectable fillers are very effective for correcting small irregularities of the nose. I generally prefer waiting at least 12 months after a primary rhinoplasty before performing any revision surgery. A filler may be an effective way to optimize appearance while waiting to the appropriate time for revision.

There are several different, safe and proven fillers available now for use in the face and nose. In general I feel much more comfortable using small amounts of filler to correct irregularities of the dorsum (the upper two thirds of the nose) rather than the tip.
The problem with the tip is that there are deep, large pores that are full of bacteria and there is a risk of infection or even possible injury to the skin. You need to make sure the doctor doing the filler understands this and injects deep, below the skin. That being said I prefer to use Radiesse right over the bone or cartilage in the dorsum. It can last for a long time. Hope this helps
