How Long After Your Primary Rhinoplasty Will Cartilage Reabsorb?

Cartilage resorption with cartilage grafts is not a desirable or expected outcome.  The cartilage was placed there to provide nasal support and presumably to shape the nasal tip.    Some cartilage resorption may happen over a year but it is usually a small amount and not enough to be clinically significant i.e. to affect the nasal appearance or structure.   In this way, cartilage grafting is a pretty reliable way of influencing the structure, appearance and function of the nose. 

From the description that you have provided. it sounds like your surgeon performed a rhinoplasty with nasal bridge augmentation with the use of auricular cartilage and temporalis fascia.  The auricular cartilage from your ear was used to provide bulk and structure to the bridge of your nose, and the temporalis fascia (the piece of tissue taken from beneath your hair) is used to provide some fullness but mostly used to camouflage the cartilage grafts that are placed.  The good news is that your surgeon used an excellent combination of material for this particular purpose, although I prefer to use septal cartilage for all grafts in primary rhinoplasty as it is readily available and does not require a separate surgical site.  You may still have a bit of swelling where the grafts were placed, but, I would not expect significant resorption of either of these tissues over time.
