I barely have cartilage in my nose tip, what can be done and how much will it cost?

Without a full set of pictures, it is impossible to give an opinion on whether the tip rhinoplasty alone or a full rhinoplasty as necessary. In our practice, the majority of patients must undergo full rhinoplasty rather than just the tip due to the relationships of the cartilages bone and skin of the nose.   Digital computer imaging would be helpful to understand what can be accomplished with your nose upon your facial features.To prevent the tip from drooping when smiling and talking, releasing the depressor septi ligament can be performed at same time as the rhinoplasty. For many examples, please see the links below

It sounds like you would benefit by a tip rhinoplasty where cartilage is added by a columellar strut to give the tip more support and resist displacement with facial motion. Expect to pay $4000 to $4500 total cost for the procedure.
