How can a sharp nasal tip be achieved? (photo)

The photo you present is a little fuzzy, so it is hard to tell exactly the skin/tissue thickness.  Otherwise I would achieve the desired effect by using a cartilage graft (taken from inside your nose) to reshape the tip.  Some surgeons prefer to insert the cartilage graft through the inside of the nostril, but I find that method less precise, so I typically use an "open" approach by lifting the skin over the tip to get the exact shape/angle/placement needed.

hi German girl. The type of tip you are looking for requires 3 things. First you need very nonglandular and thin skin. Second you need strong and well defined cartilages (can be surgically made that way). Third you may require an additional cartilage graft in the tip to creat extra definition (also can be done with surgery). If any of those 3 things are not present or not done you won't get the sharpening effect you are looking for. Good luck in finding someone to do your revision. It's not a very complicated request. 

The tip cartimages would need to be redefined to make the tip more pointy. Another good technique is to place a tip/shield graft which will provide a definition you desire.
