Is Nose Hump Made of Flexible Cartilage or Bone?

In most people, the highest point of a nasal hump is actually the junction between bone and cartilage. These are both rigid structures and need to both be addressed in nasal hump removal. Reducing the bone is by using a special surgical rasp or an osteotome (looks like a chisel). Reducing the cartilage is by using a special scissors and/or a surgical blade.

In fact its more cartilage than bone. You can't change the shape by pressure. Over time cartilage can change shape. Its thought to be due to continued slow growth possibly accelerated by injury. Short of surgery there isn't any way to change the shape.
