BACKGROUND: The EarWell System offers a correction opportunity for infants born with ear anomalies. However, the long-term effectiveness of ear molding remains unclear. This study aimed to explore the long-term effectiveness of this novel technique and to determine the risk factors for recurrence. METHODS: This retrospective, population-based cohort study was performed from 2017 through 2021. Infants who completed ear molding therapy and were followed up for longer than 6 months were enrolled. The main outcomes were immediate and long-term efficacy, which were graded by two blinded plastic surgeons. RESULTS: A total of 226 infants (334 ears) were recruited. The most common anomalies were helical deformities [113 ears (33.8%)], and the rarest were cryptotia [five ears (1.5%)] and conchal crus [five ears (1.5%)]. The age at initiation of treatment was a factor affecting both immediate ( P = 0.004) and long-term effectiveness ( P = 0.009). The type of anomaly also influenced long-term molding outcomes. For cup ears, the success rate of long-term outcomes (76.0%) was significantly lower than that of immediate outcomes (98.7%) ( P < 0.001). Prominent ear, cup ear, and microtia were found to be the most likely to relapse during long-term follow-up. The results of logistic regression also demonstrated age, duration time, and the type of anomaly to be risk factors of ear molding effects. CONCLUSIONS: The EarWell System was shown to be a secure and effective method for treatment of co...
