My Side Profile is Fine but my Nasal Bone is Too Wide

Yes, it is possible to narrow a nose without effecting the "roof" or dorsum and creating further elevation of that area. The procedure is done slightly differently and I would make sure you see a rhinoplasty expert to achieve that type of correction.

You do not need to have a dorsal hump removed to narrow your nose. Lateral osteotomies, and sometimes medial osteotomies are performed during rhinoplasty Surgery to narrow the front view of your nose. This does not need to affect the appearance of your profile or the height of your nasal bridge.

I hope this is helpful for you.
