Rib cartilage makes an excellent building material for noses but must be indicated--meaning that you have no better donor sites. Rib also varies with patient age. In young patients (under 40), rib is white and elastic, so it can curl after surgery and may need revision. Over 40, it begins to get calcified and therefore keeps its surgical shape more easily. I am not sure what "dire" means, but if your nose has healed from the last surgery, find a surgeon who can show you results using rib cartilage that you like, and is someone you can trust. You want to minimize the chances of another disappointment. Good luck!
IMHO, after performing Rhinoplasty and revision Rhinoplasty for over 20 years, rib grafts, bone grafts and banked, irradiated cartilage all historically dissolve unevenly over the years. Do a medline article search on irregular absorption of rib grafts for a more detailed picture but I do not use these grafts in Rhinoplasty and have had to remove partially dissolved grafts of rib, bone and banked cartilage and replaced them with stable, more reliable straight silastic nasal implants for the nasal bridge and conchal ear cartilage grafts for the nasal tip. Have a few more consultations, IMHO.
