Closed tip grafting - Would like to add a little more tip to the front of my nose. Is this realistic? (photos)

Hello, if u want cartilage grafts on your nose tip, you should accept that, your nose tip will be more defined and also will be longer and more projected

A rhinoplasty surgeon can certainly add definition and projection to your nose, both with suture techniques as well as cartilage grafting. I disagree with some other comments that seem to indicate cartilage grafting to the tip makes noses bigger -- that is absolutely not true when carved correctly and in an expert's hands.
Wanting this done with a closed technique is more challenging, and very few rhinoplasty surgeons (even experts) perform closed tip rhinoplasty. The benefits of closed tip include no external incisions, but then again I've never had a patient who thought their columellar incision scar was noticeable at the 12 month mark.
The most important piece of your rhinoplasty journey (in my opinion) is that you find an expert surgeon you trust. If the two of you can come up with a shape and plan you love, that's most important. Their technique (closed versus open, ultrasonic versus cold steel, etc, etc) is far secondary to that first element.
Swelling can persist for up to 1 year after rhinoplasty, although probably 80% is gone by 6 months after surgery.
Hope this is helpful!
