Abstract：【Objective】To explore the effect of noninvasive ear model on infants with congenital auricle malformation of different ages by comparing the auricle morphology data before and after treatment.【Methods】A total of 86 healthy children aged from 2 weeks to 24 weeks who only suffered from unilateral congenital auricle morphological malformation (the malformations showed helix malformation, hidden ear and cup ear) were treated with earwell auricle orthosis. After treatment, the changes of ear morphological data were compared and the curative effect was evaluated combined with various evaluation indexes. 【Results】All children were successfully treated without serious complications. After treatment, facial ear length, morphological ear width, facial ear width and morphological ear length were all longer than before treatment, and the vertical distance between cranial and ear was shorter than before treatment. The differences were statistically significant (P<0.05), However, there was no significant difference in auriculocranial Angle before and after treatment (P>0.05).There were statistically significant differences in treatment cycles, doctors' ratings of efficacy, VAS score of parents' satisfaction and the occurrence of adverse reactions in different age groups (P<0.05). 【Conclusion】The noninvasive ear mold treatment can effectively correct the congenital auricle deformity of infants. And the best effect of wearing ear mold appliance is within 6 weeks after birth.
