Objective To explore the clinical effect of non-invasive auricle orthosis in the treatment of congenital auricle malformations in children,and analyze the relevant factors affecting recurrence after correction.Methods A total of 453 ears of 292 children with congenital auricle deformities who received EarWell's auricle correction device treatment in our hospital's otolaryngology head and neck surgery from November 2019 to December 2021 were included;All children were strictly wearing braces for 2-8 weeks.Distinguish the≤2-month-old group,3-5 month-old group,and 6-8-month-old group based on the age of the child;According to the types of auricle deformities,the groups of pendulous ears,cup-shaped ears,flaring ears,and auricle deformities can be distinguished.Evaluate the corrective effect of each group 3 months after the completion of correction;Follow up for 1 year to observe the recurrence of deformities,compare the clinical data of the recurrent group and the non recurrent group,and analyze the relevant factors affecting the recurrence of auricular deformities after correction using logistic regression analysis.Results During the correction process,4 children(6 ears in total)withdrew from treatment due to various reasons,and 288 children(447 ears in total)completed the correction.The success rate of correction in the≤2-month-old group was 90.21%(258/286),which was higher than 74.26%(75/101)in the 3-5 month-old group and 53.33%(32/60)in the 6-8-month-old group,with a statistically significant difference(P＜0.05).Among different types of auricular deformities,the success rate of correction of the hanging ear is higher than that of cup-shaped ear,auricular deformities,and flaring ear(94.05%＞80.00%＞59.76%＞41.67%),and the difference is statistically significant(P＜0.05).Following up for one year,out of 365 cases of successfully corrected auricular deformities,47 cases recurred,with a recurrence rate of 12.88%.Multivariate logistic regression analysis showed that the initial correction age(OR=1.832)and the length of appliance wear(OR=0.741)were independently correlated with recurrence after non-invasive correction(P＜0.05).Conclusion The effectiveness of non-invasive correction treatment for children with auricular malformations is related to the age of the child and the type of auricular malformation.The initial correction age and the duration of appliance wear are related to recurrence after successful correction.
