Abstract:Objective To evaluate the effect of noninvasive auricular orthosis in the treatment of children with congenital auricular malformation, and to explore the influencing factors. Methods A total of 353 children (490 ears) with congenital auricular malformation who received EarWell auricular orthosis at Huangshi Maternal and Child Health Care Hospital from June 2020 to August 2023 were included in this study. According to the age of starting treatment, they were divided into three groups, Group A (≤7 days, 128 cases, 202 ears), group B (8-42 days, 123 cases, 162 ears), and group C (43-90 days, 102 cases, 126 ears). The clinical effect and complication rate among the three groups were compared. The children were followed up and divided into a good prognosis group and a poor prognosis group according to their prognosis. Logistic regression analysis was used to explore the factors affecting the prognosis of children with auricular malformation. Results The clinical effective rate of group A was higher than those of group B and group C (P<0.05). The incidence of adverse reactions in group A was lower than those in groups B and C (P<0.05). The results of follow-up revealed that 283 cases had good prognosis and 70 cases had poor prognosis. The differences in age, facial ear length, Max classification of auricle malformation and atresia grade between the two groups were statistically significant (all P<0.05). Logistic regression analysis showed that age and Max classification of auricular deformity were the factors affecting the prognosis of EarWell auricular orthosis correction.Conclusions Orthotic treatment has a remarkable effect on the correction of congenital auricular deformity. Age and Max type of auricular malformation are the key factors affecting prognosis.
