I want to get a cartilage based rhinoplasty only and wanted to see if that is possible for nose bridge narrowing? (Photos)

Why limit what can be achieved? Why handcuff the surgeon by telling her or him that they cannot do a typically necessary step?
IF your nose bridge is wide from bone, removing or adjusting bone is needed.

Hello and thank you for your question. Based on your photographs, you may benefit from a tip refining rhinoplasty. A surgeon can accomplish this by trimming, suturing, and reshaping the cartilage in your lower nose. Fascial grafts may also be used to help improve tip refinement. With good surgical technique, you could have an outstanding result. I recommend that you seek consultation with a qualified board-certified rhinoplasty surgeon who can evaluate you in person.

Best wishes and good luck.

Based on the photographs, it appears possible to reshape your nose by altering and refining the cartilage. Of course, the excess soft tissues would also need to be removed. However, I should also say that in noses like yours, even if the bony part is addressed, it is possible to carry out the operation using preservation techniques which maintain the bone-cartilage integrity, enabling a comfortable surgical process.For our patients we use 3D imaging to show how it would look with just a cartilaginous rhinoplasty as well as with a full rhinoplasty. I would recommend that you have a professional consultation so you can receive further information.
