Abstract:
Objective:To investigate the self-healing of congenital auricular deformity (CAD) and the efficacy of the auricle corrector in infants.Methods:The infants with CAD who were born in the Affiliated Maternity and Child Health Care Hospital of Nantong University from January to December 2020 were collected. The patients who disagreed with the use of auricle corrector were included in the observation group. The patients were followed up on the day of one month and one year after birth by phone or WeChat, and the self-healing rate (the proportion of the number of ears found to be healed in the total number of affected ears after follow-up) of auricle was calculated. The patients treated with auricle corrector were included in the non-invasive correction group, which was treated with domestic auricle corrector. And according to the initial correction age, the patients were divided into ≤7 d, 8-28 d and >28 d three subgroups. The patients were followed up on the day of one month and one year after treatment by phone or WeChat, and the effective rate(the proportion of healed ears to the total number of affected ears after treatment) was calculated. And statistical analysis was used in the three subgroups of initial correction age ≤7 d, 8-28 d, >28 d. Variance analysis was used for general comparison between three groups, and LSD- t test for the comparison between two groups. P<0.05 was considered statistically significant. Results:A total of 43 children (71 ears, 34 left ears and 37 right ears) were included in the observation group, including 21 males and 22 females, (2.1±0.3) days after birth. In the non-invasive correction group, 24 children (41 ears, 20 left ears and 21 right ears) were included, including 8 males and 16 females, (29.1±23.8) days after birth. There were 6 cases (10 ears) in the initial correction age group ≤7 days, 6 cases (9 ears) in the 8-28 days group, and 12 cases (22 ears) in the >28 days group. In the observation group (71 ears), the rates of self-healing on the day of one month and one year after birth were 29/71 and 30/71, respectively, including 23/31 and 24/31 for lop ear, 3/6 for Stahl’s ear, 3/3 for complex deformity, and 0 for other ear deformities. The effective rates were 41/41 and 35/41 one month and one year after treatment in the 24 children (41 ears) in the non-invasive correction group, respectively. Among them, the helical rim deformity was 12/12, lop ear 3/3, cup ear 7/7 and 5/7, Stahl’s ear 4/4, contracted ear 6/6, 5/6, prominent ear 2/2 and 0, the complex deformity 6/6 and 5/6, and microtia(Ⅰ) 1/1. The auricular deformities reoccurred in a total of 4 children (6 ears) 1 year after the end of treatment. According to the initial correction age into three groups, the treatment duration of the auricle corrector was (31.8±11.2) days, (31.3±10.1) days and (41.8±13.8) days, and the difference among the three groups was statistically significant ( F=3.42, P=0.043). There was no statistical significance between the groups ≤7 days and 8-28 days ( P=0.936), but there was statistical significance in the treatment duration between the groups ≤7 days and >28 days ( P=0.043), and between the groups 8-28 days and > 28 days ( P=0.041). Conclusion:CAD can self-heal to some extent. Self-healing rate is higher in lop ear and Stahl’s ears. The domestic auricle corrector has a good effect on CAD. The older the age of initial correction is, the longer the time of correction is. The type of CAD has a certain influence on the correction effect.
