Objective To study the clinical effect of non-surgical correction of congenital auricular deformities in infants.Methods A retrospective study was performed to 201 infants (318 ears) treated with non-surgical auricular correction from January 2019 to December 2021 in our hospital. According to the age of starting treatment, they were divided into 3 groups:the infants younger than 14 days of age belonged to group 1 (109 infants, 181 ears), infants aged 14-42 days to group 2 (75 infants, 117 ears), and those aged 42-89 days to group 3 (17 infants, 20 ears). Then their outcomes, treatment durations, and complication rates were calculated and compared.Results Of all the 201 infants (318 ears), the total success rate was 93.4%, the average treatment duration was (32.4±10.8) days, and the incidence of complication was 45.9%. The success rates of the three groups were 96.7%,90.6% and 80.0%,respectively (χ²=10.479,P=0.005), indicating statistically significant differences. The treatment durations were (30.2±10.4), (35.2±10.8) and (35.5±9.7) days respectively, and their differences were statistically significant (F=8.940,P=0.000). The incidences of complication were 37.0%, 59.8%, and 45.0% respectively, and the differences were also statistically significant (χ²=14.900, P=0.001).Conclusions Non-surgical correction of auricular deformities in early time has a significant molding effect. Treatment within 14 days is beneficial to improving treatment efficiency, shortening the treatment duration, and reducing the incidence of complication.
