Is Lowering the Nose Tip Difficult After a Previous Surgery? (photo)

Although it is hard to tell from just one view it appear that you have an over-resected bridge and perhaps even a pollybeak - revision surgery, possible with rib graft, would be needed.

The typical rhinoplasty is usually to make a nose smaller and shorter. However, we can also raise the bridged of a nose and lengthen a nose as well. This can be performed in both primary and revision Rhinoplasty. Grafts of your own cartilage are used to make these changes. This is a challenging procedure and I recommend you seek out a Rhinoplasty specialist for nasal lengthening surgery.

Certainly revision rhinoplasty can be performed on your nose in order to narrow and refine the dorsal aesthetic lines. Pushing the tip down is possible through different suturing tip techniques. It appears in the picture that you may have some alar flair and this can be brought back down with composite grafts from the ear. Finding an experienced rhinoplasty specialist for a complete evaluation would be necessary prior to making an informed decision of what would be appropriate for revision rhinoplasty on your nose. 

Yes, any secondary Rhinoplasty is difficult but lowering the tip in a predictable manner is very challenging.

The nose can be lengthened and the bridge augmented with rhinoplasty surgery. Most often, your own cartilage is used to achieve the desired length and definition. In your case see an experienced revision rhinoplasty surgeon.
