How to Fix Wide Nose Bridge?

When osteotomies are needed to narrow a wide nasal appearance, this is typically performed at the time of rhinoplasty. Depending on your examination, you may require medial osteotomies (along the roof of your nasal bridge), and lateral osteotomies ( along the path where your nasal bones meet your facial bones. Hope this is helpful. Dr Joseph

It appears that your nose may also be underprojected which would be better determined with a profile photo.  If this is the case, the treatment should involve a combination of  osteotomies to narrow the bones, in combination with some cartilage grafting which will both improve the projection but also provide a more narrow bridge.

Judging from the photo you provided, you have a depressed nasal profile where the tip is more prominent than the remainder of your bridge; this is called a saddle nose. This flattening makes a nose look very wide.
Saddle nose deformities are common after nasal trauma, severe nasal infection, prior nasal surgery - to name just a few reasons. Or, it may just be the way your nose has developed.
In this situation, an augmentation of your nasal bridgewill provide the appearance of a more balanced and narrower nose, even without narrowing anything. Sometimes, the more narrowing can be achieved by moving your nasal bones closer together.
