First, consider the calcification factor. Costal cartilage is its own cartilage tissue, which will be calcified more or less after being placed on the nose. There is no way to avoid this situation. You can search the information on the Internet. Therefore, the whole rib will be partially atrophied, not to mention the calcified absorption caused by soft rib cartilage particles.
Second, consider the shaping effect. What do you want for rhinoplasty? The important thing is that the effect is high and natural, and it has certain plasticity. However, the shaping degree of soft cartilage particles must not be as high as that of the whole root, and soft cartilage particles need to be wrapped in artificial dermis for shaping, otherwise it will be more troublesome for soft cartilage particles to be scattered throughout the bridge of the nose.
Third, postoperative safety. If there is something wrong with the whole rib, it is relatively easy to take it out, and there will be no uncleanness or carelessness. However, soft cartilage particles are hard to say. Once there is a problem, if you want to take them out, every particle may be scattered in the cavity of the bridge of the nose.
Therefore, since we have decided to remove the rib by surgery, there is absolutely no need to shape it into particles, just carve the cartilage according to your personal bridge of the nose.
