I know that dorsal humps can only be removed by surgery. Can the hump grow and get worse throughout my future?

The paired nasal bones which form part of the dorsal hump along with the septum will not grow further after you reach facial skeletal maturity usually in your late teens after puberty.  Changes to the facial skeleton do occur later in life but mostly consist of loss of bony volume and soft tissue volume with age.  

Thank you for your question.  No, once you are an adult and fully grown, a dorsal (nasal bridge) hump should not continue to grow.  A dorsal hump can be acquired if you break your nose, and the nasal bones shift.  In addition, a hump can be caused by both cartilage and bone within the septum, which both need correction. We usually refine and reduce a dorsal hump in conjunction with a rhinoplasty.  Most often, and depending on the severity of the hump, you may need osteotomies (a precise cut in the nasal bone) to close what is called an open roof deformity.Finally, be sure to consult with someone who is specialized in rhinoplasty. A dorsal hump can "reappear", not because it grew back, but because the nasal tip drops.  It is important that the nasal tip be supported during your initial surgery to prevent this. Consult with a board certified facial plastic or general plastic surgeon who specializes in rhinoplasty. I hope that this helps, -David Gilpin

Dorsal nasal hump does not continue to grow.  Once adulthood has been reached the growth of the nasal bones stops.  During most of the adult life it is not noticeable in terms of any change or growth.  However once you grow old and the tissues become loose and sagging it can enhance the appearance of a nasal hump.RegardsDr. J
