Abstract：Objective: To explore the growth of reconstructed auricles and analyze the related factors affecting the formation of cranioauricular angle. Methods: The clinical data of 120 patients with unilateral auricular reconstruction were retrospectively analyzed. The auricle projection areas of reconstructed ear and normal ear were compared before operation and at 3 months, 6 months and 12 months after operation. According to formation of cranioauricular angle of reconstructed ear, the patients were divided into poor group (n=24) and satisfactory group (n=96). The clinical data of the two groups were compared by univariate analysis, and the items with statistically significant differences in the comparison result were given Logistic multivariate stepwise regression analysis. Results: At 3 months, 6 months and 12 months after operation, the auricle projection area of reconstructed ear was significantly higher than that before operation, and there was no statistically significant difference compared with that in normal ear at the same time (P>0.05). There were no significant differences between the two groups in gender, reconstructed auricles, skin blisters, ear piercing or skin care (P>0.05), but age≥13 years old, scar hyperplasia and no use of ear protectors were independent risk factors for poor formation of cranioauricular angle (P<0.05). Conclusions: Auricle growth is good in patients after auricle reconstruction, and the surgical procedure is very feasible. And the effect of cranioauricular angle formation is closely related to age, scar hyperplasia and the use of ear protectors. Clinical diagnosis and follow-up interventions are required to cause enough attention.
