What Does It Cost to Reduce Nasal Flare?

The cost of rhinoplasty involves the surgeons fee, the anesthesia fee and the facility/hospital fee. Prices vary widely depending on the surgeon and the city/location. Rhinoplasty is not usually broken down al-a-carte, since the nose should be viewed a while - making a change in one part can affect other parts. Good luck with your procedure.

The general use of ear cartilage grafts is for augmentation of nasal structures that either need more support, or more projection in certain parts of the nose. 
Although cartilage grafts could work for strengthening of the alar rim (nostril), in general this would not reduce flare to a great degree.  Alar base reduction using incisions to remove skin from this area is more consistent for reduction of alar flare. 
You can see some examples on my website.
I hope this helps.
