L-shaped prosthesis is easy to "bulge" from the tip of nose after pressure impact, so it is suggested to use auricular cartilage pad as the protective pad of L-shaped nasal prosthesis. A small piece of auricular cartilage is usually placed between the prosthesis and the skin and soft tissue at the tip of the nose. Its main function is not only to cushion the height, but also to cushion the pressure impact of the prosthesis on the nasal tip and prevent possible skin penetration problems. Without self-rejection, you can better integrate.
