Objective To explore the effect of using porous high-density polyethylene material combined with autologous auricular cartilage for nasal tip scaffold construction in nasal tip plasty. Methods A total of 56 patients who underwent nasal tip plasty at the Fifth Affiliated Hospital of Xinjiang Medical University from October 2023 to October 2024 were selected as the research subjects. According to different rhinoplasty methods, they were divided into the control group and the observation group, with 28 patients in each group. The control group was treated with autologous auricular cartilage for nasal tip scaffold construction, and the observation group was treated with porous high-density polyethylene material combined with autologous auricular cartilage for nasal tip scaffold construction. Expanded polytetrafluoroethylene was used for nasal dorsum filling in both groups. The nasal measurement indexes, satisfaction and complications were compared between the two groups. Results After operation, the nasal dorsum length and nasal tip height of the observation group were greater than those of the control group, and the nasolabial angle and nasal tip angle were smaller than those of the control group (P <0.05). The satisfaction rate of the observation group (96.43%) was higher than that of the control group (78.57%) (P <0.05). The incidence of complications in the observation group (7.14%) was lower than that in the control group (10.71%), but the difference was not statistically significant (P >0.05). Conclusion The application of porous highdensity polyethylene material combined with autologous auricular cartilage for nasal tip scaffold construction in nasal tip plasty can effectively improve the nasal appearance without increasing the risk of complications, which is beneficial for improving patient satisfaction and is worthy of clinical application.
