Is this amount of reduction possible? (Photo)

From the photo, you are a great candidate for rhinoplasty the bridge can be taken down like you ask. After that, the nasal bones will be brought back together so it will look thinner from the front as well. Be sure to see a rhinoplasty specialist for consultation.

Hello, and thank you for your question. While a face-to-face evaluation is necessary (surgeons will need to see your entire facial profile too) to determine the right nasal shape for you, surgical
rhinoplasty can help those who are unhappy with the appearance of their nasal bridge achieve a more refined and contoured nose. I recommend scheduling an in-person consultation with a reputable board-certified facial plastic surgeon, particularly one with a strong rhinoplasty portfolio. Such experts will have the optimal skills, as well as artistry and knowledge of facial aesthetics, harmony, and proportion, to help you achieve the most natural-looking results. During your consultation, your surgeon will evaluate your nose and facial profile, discuss your concerns and goals, recommend the best surgical approach, use digital photography to show projected results, and ensure the best possible outcome.

Dear Heather199282,
it is hard to tell for sure without an examination. Based on your photos, it looks like your results would be possible, If you are considering surgery, I would suggest you consult a board-certified plastic surgeon. Only after a thorough examination, you will get more information and recommendations.
