The goal of any rhinoplasty is to produce a nose that looks natural and functions well. One of the most common reasons that patients seek rhinoplasty consultations is to learn about dorsal hump reduction.
A dorsal hump is comprised of bone and cartilage. To remove the hump, the rhinoplasty surgeon files down the bone and trims the cartilage to the appropriate height to give the profile the desired contour.
Sometimes, it is possible to correct one isolated problem -- such a a dorsal hump -- without having to change or disrupt other parts of the nose. More frequently, small adjustment need to be made to other parts of the nose to keep the nose proportional and in balance with the other facial features.
One of the most beneficial aspects of a rhinoplasty consultation is having your photographs morphed (computer simulation) to give you an idea of how your nose might look with various changes. Recently, 3D imaging has become available (see link below).
