Background and purpose: Many studies recommend nonsurgical auricular correction during the early postnatal period, when cartilage plasticity is high; however, many patients are not eligible for the procedure. This study compared different timings of nonsurgical auricular correction to investigate benefit after the optimal period for correction.
Methods: In this prospective study, 53 ears from 35 patients with congenital auricular anomaly were assigned to two groups according to age at correction: the "early-group" with correction within 2 weeks of birth and "late-group" with correction 8 weeks after birth. Aesthetic outcomes, caregiver satisfaction, detachment rates and mean device-wearing periods, were compared.
Results: Thirty-one ears from 20 patients comprised the early-group, and 18 ears from 12 patients comprised the late-group. Mean time to treatment after birth was 9.09 days in the early-group and 134.7 days in the late-group. In the early-group, detachment occurred in 4/31 ears (12.9%), and in the late-group, detachment occurred in 12/18 ears (66.7%), which was statistically significant (p<0.01). The average period of applying devices was 4.7 ± 1.2 weeks in the early-group and 8.5 ± 4.1 weeks in the late-group, with a significantly longer treatment time in the late-group (p=0.001). The early-group had 87.1% "good" results vs. 55.6% in the late-group, with a statistically significant difference.
Conclusions: The correction period was shorter, detachment rate was lower, and treatment outcome was better in the early-group. However, successful correction was also present in the late-group, showing that the patients who have passed the optimum correction period should proceed after counselling.
