Can my nasion be lowered through Rhinoplasty? (photos)

You have high and prominent frontalis nasal extension, this is the cause of your high radix; this can be corrected during a rhinoplasty along the rest of features you wish to change on your nose.

Based on your photos- it appears that you would benefit from rhinoplasty. Seek an experienced Board Certified PS for in-person exam, view the surgeon's before/after photos.
