Is it possible to get a more curved / concave nose bridge particularly where the nose joins the forehead? (photo)

The point at which the nose enters the forehead( radix and glabella)  can be reduced with a combination of osteotomes and rasps to deepen the nasal frontal crease. Osteotomies of the nasal bones will most likely be required, otherwise a flat top nose will result.  A full set of facial photographs and an in-person examination going to be required to make that determination. For many examples, please see  the link below to our rhinoplasty photo  gallery

The radix can be reduced through a closed approach.Select a plastic surgeon who performs hundreds
of rhinoplasties each year, has great reviews, and great before and
after pictures.Kenneth Hughes, MDLos Angeles, CA

This area can be made more deep. There are three ways to do this.  There is a special osteotome.  There are handheld curved rasps (I don't find these to be that useful).  One can also use an electric shaver/burr that is used for arthoscopic surgery.  This is my preferred method because it is precise and efficient.
