Filler Now, Small Revision Rhinoplasty Later for Nose Dent?

The filler option is fine, as long as you are about a month or more post revision. If you try to use it too quickly after a surgery, the results are less predictable. The choice of product like restylane, juvederm, or radiesse is not that critical, but if you are looking only for a year effect, stick with restylane or juvederm.
Some long term studies have shown that restylane (and therefore very likely juvederm) induces collagen deposition of your own during healing. So it is possible that you can get more lasting results with only using filler if you wanted to avoid a third surgery. However a couple of injections in series would be required. Just an option. The fillers are very precise, safe and natural.

Soft tissue fillers can be used in certain situations to correct deformities of the nose. One of the more common uses is to fill depressions of the nose especially after surgery. A filler can be used to achieve a temporary result while waiting for revision surgery. In some cases, where a small depression is the only concern, having an injection of soft tissue filler every year or two to maintain the result may be more practical and affordable than undergoing revision surgery. There are several important considerations when using soft tissue fillers in the nose to improve safety and prevent both short and long term complications. Use temporary fillers NOT permanent (Silicone, Artecol). Use gel fillers NOT particulate (Radiesse, Sculptra). The amount of filler injected at one time must not be excessive as this can cause problems with not only the appearance but also the blood supply. Hyaluronic acid fillers are ideal for injection into the nose as they are temporary (usually last for over 1 year) and gel. Additionally, if too much filler is injected or there are problems with blood flow to the nose, an enzyme (hyaluronidase) can be injected to dissolve the product and reduce the risk of skin loss and scarring. Both Juvederm and Restylane are commonly used hyaluronic acid fillers. Another consideration is that you have had previous surgery which causes the skin to be less pliable, so injecting fillers can be more challenging.You would benefit from seeing a board certified plastic surgeon that performs both revision rhinoplasty and soft tissue filler injections into the nose to see what would be an appropriate option for you.

The current role of hyaluronic acid fillers that are non-particulate fillers such as hyaluronic acid fillers like Juvederm or Restylane are good temporizing fillers to correct small nasal indentations that will allow one to wait and look good while you’re waiting for the nose to mature. One can then do a true revision rhinoplasty 12-15 months after the procedure if one is needed.
