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
