Add height to bridge during revision or with fillers or not at all?

There are several techniques by which you can add height to the dorsum of your nose to correct an over-resected bridge. Without photos or examining you in person, it would be difficult to guide you to the technique that would provide the best result. Fillers, implants, using your own septum as a graft -- there are many possibilities. I suggest you find a board certified plastic surgeon who specializes in revision rhinoplasty and see him or her in person or arrange for a phone consultation.

If she do not like the mild ski slope deformity and you should start with a fillers.  A filler such as hyaluronic acid will give you an idea of what to expect if you get a permanent graft in place.  If you like the appearance after the filler than most likely you like the permanent appearance after a very small graft.RegardsDr. J

While fillers can augment the dorsum, the results will be temporary. You might be better off with a revision rhinoplasty using grafts to augment your dorsum.

There is no way to tell you what maneuvers need to be done without seeing photos.  Regardless of height being the actual issue, there are many things that can be done during a revisions to fix a low perceived height or projection.  Filler is good only for mild irregularities.  No one wants to do filler life long. It would be best to find a revision rhinoplasty expert and get a consultation. One whose results impress you 

Regardless of how little you are trying to raise your nasal dorsum both a non-surgical or surgical approach are effective and reliable techniques; You just have to decide whether you are seeking a permanent or temporary correction.

If you decide to change the height of your bridge do it when you revise the tip so you have permanent correction rather that using fillers that must be injected periodically the rest of your life.
