Hello, all operations are risky. As long as you find an experienced doctor, the risk will be minimized or even zero. Are you satisfied with the height of the tip of your nose? If you are simply dissatisfied with the bridge of the nose, you can pad the bridge of the nose with swelling. If you are not satisfied with the tip of the nose, you can use autologous cartilage as the tip of the nose, which will be much more stereoscopic.
