Will my rib cartilage become weaker after rib-harvesting rhinoplasty?

A small portion of the cartilaginous portion of the rib is taken (for my patients usually 4 cm from the right 6th rib).  You will not have any untoward effects in terms of health or function, and this is well tolerated even in my patients who are professional boxers and mixed-martial artists.  The biggest downside to have rib cartilage harvested is a thin 2 cm scar which will be present in the crease under your right breast.  

Asian rhinoplasty without using rib cartilage is something I have done for 35 years. I use only septal and ear cartilage and have never had to use rib. Choose an experienced rhinoplasty surgeon who does many revisions without using rib.

Rib is preferred by some surgeons for source of  cartilage to augment an Asian nasal dorsum.  Other surgeons like to avoid rib if possible.  Harvesting rib cartilage will not weaken your chest wall.  Some anxiety regarding an upcoming surgical procedure is normal. Its good that you have gone on multiple consultations.  Have confidence in your selection of surgeon and try and relax.  All the Best,Dr. Brian Reagan
