The cartilage of the removed auricular cartilage was cut at the thin tip with a length of 5 mm and a width of 8 mm and was used as a cap graft or shield graft at the tip of the nose (Video 3; Figure 1).

At this point, an intact ear cartilage scaffold was formed (Video 4; Figure 2). Finally, the prepared otoconia cartilage was sutured and fixed at the tip of the nose as a cap graft or shield graft, and the fascia muscle tissue on the back of the removed otoconia cartilage was covered on the shield graft or cap graft so that the tip of the nose was basically formed (Video 5; Figure 2).
