Own Rib cartilage graft vs cadaver rib, are they equally strong for Rhinoplasty? Are they the same risks?

For more than 35 years of rhinoplasty I have rarely had to use rib cartilage of either type.  The patient almost always has enough cartilage in the septum and ears for all that is needed!

Your own tissues will always be a better source of graft material than cadaver tissues or foreign substances such as silicone. These alternative graft sources carry a higher risk of resorption, exposure, or infection.  Although septal cartilage is frequently used in primary and sometimes secondary (or revision) rhinoplasty, it is often underestimated how much is required to achieve a specific goal, especially during secondary rhinoplasty.  The question of whether or not to use a rib graft is largely related to the severity of the nasal deformity and the goals that one is trying to achieve.  

I do never recommend using tissue bank cadaver cartilage, always own patient's tissues are the rule in my practice. In spite some thorough studies about irradiated cadaver rib show their efficacy... it is hard to believe from my side, since that is "dead" by irradiation tissue, its long term stability should be seriously questioned.
