Abstract:
Objective:To investigate the efficacy and safety of auricular composite tissue particle injection in the treatment of nasal collapse.Methods:Patients with flat nose in Yuyao People′s Hospital of Zhejiang Province from June 2021 to June 2023 were retrospectively enrolled, and were divided into two groups according to the treatment methods: Observation group, 41 cases were treated with ear complex tissue granule injection, including 16 males and 25 females, aged 19-45 (27.2±1.6) years; Control group, 54 cases underwent silicone prosthesis implantation, including 21 males and 33 females, aged 18-46 (26.4±1.8) years. The satisfaction rates of nasal tip and nasal shape at 1 week, 6 months and 1 year after surgery were compared between the two groups, and the effect maintenance rates of patients at 6 months and 1 year after surgery were compared between the two groups, and the occurrence of adverse reactions in the two groups was recorded.Results:The satisfaction rates of nasal tip at 1 week, 6 months, and 1 year after surgery were 79.6% (43/54), 64.8% (35/54), and 48.2% (26/54) in the control group, and 92.7% (38/41), 78.1% (32/41), and 63.4% (26/41) in the observation group, respectively, and the difference was not statistically significant (all P>0.05). The satisfaction rates of nasal shape at 1 week, 6 months and 1 year after surgery were 79.6% (43/54), 55.6% (30/54) and 40.7% (22/54) in the control group and 90.2% (37/41), 75.6% (31/41) and 56.1% (23/41) in the observation group, respectively, and the difference was not statistically significant (all P>0.05). There was no significant difference in the effect maintenance rate between the two groups at 6 months and 1 year after surgery (all P>0.05). The total incidence of adverse reactions in the observation group was 4.9% (2/41), which was lower than that of 27.8% (15/54) in the control group ( P=0.004). Conclusion:Compared with silicone implantation, there is no significant difference in the nasal tip, nasal shape satisfaction rate and effect maintenance rate of the auricular composite tissue particle injection in the treatment of flat nose , and the incidence of adverse reactions is low.
