The use of conchal cartilage in restoring cephalic strip to enhance the size of tip orientation.

Your nose warrants a very diligent examination. As far as I can tell form the photos, the cartilage that is missing in your nose will need replacement. The decision where to harvest the cartilage from would be made during surgery. Nasal septum or ear cartilage are the likely choices. Your nose can be corrected through an endonasal approach, the incision accross the columella can be spared.

The appearance of the tip of your nose is due to the vertical orientation of the lateral crus of the lower lateral cartilage.   I woulld discouragee over resection of the cephalic margin of this cartilage because it will  create retraction  of the nostril margin and a surgical appearence.   The lateral crus of your  lower lateral cartilage needs to be  reoriented in a more horizontal position and  refined.  This willl improve the nostril margin as well as refinement the width of the nasal tip.  Cartilage  grafting is sometimes necessary to achieve this change.  Since you have had previous nasal surgery it is hard to say that  adequate cartilage which still exist inside  the nose and cartilage may need to be harvested from the ear or rib.
