Objective To analyze the aesthetic effect of combined application of autologous auricular cartilage nasal tip shaping and prosthetic rhinoplasty in nasal aesthetic plastic repair. Methods A total of 90 patients who underwent nasal aesthetic plastic repair in Xi'an Chang'an Wuwei Meidu Medical Beauty Clinic from February 2023 to February 2024 were selected as the research subjects, and they were divided into the reference group and the experimental group by the random number table method, with 45 patients in each group. The reference group was treated with prosthetic rhinoplasty, and the experimental group was treated with autologous auricular cartilage nasal tip shaping on the basis of the reference group. The surgical indicators, aesthetic effect and complication rate were compared between the two groups. Results There were no significant differences in operation time, intraoperative blood loss and nasal septal cartilage harvesting amount between the two groups (P >0.05), but the postoperative wound healing time in the experimental group was (10.15±1.27)days, which was shorter than (12.47±1.30)days in the reference group (P <0.05). The postoperative nasal tip length and nasal tip height in the experimental group were higher than those in the reference group, and the nasal labial angle was better than that in the reference group (P <0.05).The incidence of complications in the experimental group was 4.44%, which was lower than 26.67% in the reference group (P <0.05). Conclusion Prosthetic rhinoplasty combined with autologous auricular cartilage nasal tip shaping in nasal aesthetic plastic repair can shorten the postoperative wound healing time, improve the aesthetic effect, and reduce the incidence of complications.
