It can be used.
However, if you want to make the tip or bridge of the nose higher than in the first surgery, you will need a larger and stronger support structure than the septal cartilage used previously. So, if you want a higher nose, it is recommended to use a firmer material than the septal cartilage used in the first surgery. That is why rib cartilage is commonly used in revision surgery. Some people want revision surgery using ear cartilage, but ear cartilage is usually smaller and less supportive than septal cartilage, so it is not suitable for revision surgery intended to make the nose higher.
Then, if you are making the nose higher, does that mean the septal cartilage used in the first surgery cannot be used?
That is not the case. During revision surgery, we can graft the previously used septal cartilage onto the nasal tip to sculpt and shape the tip. It can also be used to add volume to the bridge or other areas. However, if the existing septal cartilage is too small, ear cartilage may be harvested and grafted onto the nasal tip as well. This depends on the situation, so sufficient discussion before surgery is necessary.
