Are there any risks associated with adding cartilage on the bridge of nose after rhinoplasty to straighten the bridge?

If you're own cartilage from the nasal septum or the ear is added to the nasal dorsum.  It should work well.  The risk of the cartridge moving is always there but it is very small compared to an implant.RegardsDr. J

You have to understand that there is no such thing as the “perfect” nose. As rhinoplasty surgeons, we are able to improve the structure and function of the nose to address specific issues you have with how your nose looks and and how well you can breathe. Perfect symmetry does not exist in nature. Attempts to improve the symmetry of your nose should be aimed at achieving an improvement in your asymmetry to the point where it is no longer very noticeable. If you look carefully enough, you will always be able to find imperfections. The goal is a normal looking nose that is in harmony with the rest of your anatomy.

The risks of adding cartilage to an overresected dorsum are graft malposition.  I recommend relaying your concerns to your surgoen, or if you don't feel comfortable, an experienced rhinoplasty surgeon will be able to discuss the options with you.  I recommend consulting with a Board-Certified plastic surgeon who will accurately examine you, create a simulation based on what you could look like with revision surgery, and develop a plan tailored to your needs.  Best wishes!

Cartilage grafting is one way to treat the low dorsum. The cartilage can warp and bend as a risk of surgery. Best of luck.

Using cartilage grafts over nasal dorsum to increase dorsal height and improve the profile is a commonly performed procedure. The sources of cartilage may be nasal septum (unless your septum was already operated), ear cartilage, or rib cartilage. The main problem with cartilaginous dorsal inlay grafts is malpractice/ asymmetry. There are various techniques to minimize this risk, such as wrapping the cartilage in soft tissue, mincing the cartilage, or suturing the cartilage, however none of these techniques are perfect. There is a role for filler injection to correct the dorsum, which has its pluses and minuses. You should consult a rhinoplasty specialist to discuss your options. 

There are risks with every surgical procedure. Having said that there are several ways to augment the bridge successfully. Cartilage strips or fascia can be added but I prefer to use diced cartilage and fascia grafts. Consult with a revision rhinoplasty specialist.
