Is there any other way to lengthen nose besides adding cartilage graft?

There isn't a great way to lengthen the nose without the use of cartilage grafts. Sometimes tip suturing or other maneuvers can help add length, but without a graft of some sort to maintain that length it is not stable. The good news is that, in primary rhinoplasty, that cartilage graft almost always can come from your nasal septum, so there is no secondary donor site. We also have fresh frozen cadaveric rib cartilage which is a great source of graft material in revision noses and difficult cases where the septal cartilage is insufficient.

Is there any way to lengthen a nose other than by cartilage grafting? Cartilage grafting is the only way I know of to lengthen a nose, and even that is not very effective in lengthening it by more than a very small amount.

Hi there! To increase the length of the nose, there are options. Non-surgically, filler is one choice and can easily be done in clinic. Some surgeons will place PDO threading. Suturing techniques do exist through a closed approach. Cartilage is ideal, though, because it provides a framework of support. Over time, the nose will tend to droop without proper stability. Hope that helps.

Hi and welcome to our forum!
Without photos, I cannot visualize your specific concern.
In general, a minimal degree of nasal lengthening can be accomplished local tissue rearrangement, but more significant lengthening requires the use of a cartilage graft, a bone graft, or with insertion of prosthetic material (such as silicone rubber).
Visi a board certified plastic surgeon for evaluation of your specific condition and discussion.
