Intervention 1: Suture is a non-destructive method and helps maintain the context and integrated structure of cartilage which is helpful in formation of the tip and vestibule. Using this way, each side of the dome can be narrowed down to a limited extent and as a result the tip can also be narrowed down to a certain level. Intervention 2: VDD Method is destructive and as a result cartilage scaffold gets damaged and elasticity characteristic of the cartilage is lost in the place where it is cut. However, using this technique more severe changes in the tip can be made and reduce the width of the tip more.
