Ear Molding Therapy of Congenital Ear Anomalies: Long-Term Aesthetic Outcomes and Caretaker Satisfaction

INTRODUCTION

Ear molding is a safe, non-surgical approach to treat newborns with congenital ear anomalies. In this study, we aimed to investigate long-term aesthetic outcomes and caretaker satisfaction from ear molding therapy.

METHODS

A retrospective chart review from 2018 to 2020 was conducted for infants who underwent ear molding treatment at our institution. Patient demographics and treatment related variables were collected. Caretakers were surveyed regarding their experience, expectations, and aesthetic outcome at 1 year (short-term) and 3 years (long-term) from treatment. Independent physicians evaluated treatment efficacy. Responses were converted to a Likert scale (1-5), with 5 representing most desirable.

RESULTS

Overall, 38 of 42 patients participated in our long-term study (90%) for a total of 62 ears. Average follow-up was 3.31 ± 0.50 years after completion of treatment. Mean age at treatment was 23.2 ± 19.7 days with a mean treatment duration of 21.7 ± 7.7 days. Caretakers' satisfaction regarding auricular appearance remained high (short-term: 4.18 vs. long-term: 4.17, p = 0.54) and anticipated social distress decreased over time. Physician aesthetic evaluations were favorable between "somewhat effective" and "very effective" and remained consistent over time (short term: 3.46 vs. long-term: 3.31, p = 0.31). Furthermore, physician evaluations were higher for deformations than malformations (p = 0.04) and in children who began treatment by 30 days old (p = 0.04).

CONCLUSION

Caretaker satisfaction from ear molding therapy remained high after long-term follow up, and social distress from the perception of their child's ears decreased with time. Physician aesthetic ratings confirmed efficacy, with better outcomes seen in deformations than in malformations.

Non-surgical Correction of Congenital Ear Anomalies: A Review of the Literature

Congenital ear anomalies have been known to cause lasting psychosocial consequences for children. Congenital ear anomalies can generally be divided into malformations (chondro-cutaneous defect) and deformations (misshaped pinna). Operative techniques are the standard for correction at a minimal age of 5–7, exposing the children to teasing and heavy complications. Ear molding is a non-operative technique to treat ear anomalies at a younger age. Having been popularized since the 1980s, its use has increased over the past decades. However, uncertainties about its properties remain. Therefore, this review was conducted to look at what is known and what has been newly discovered in the last decade, comparing different treatment methods and materials. A literature search was performed on PubMed, and 16 articles, published in the last decade, were included. It was found that treatment initiated at an early age showed higher satisfactory outcome rates and a shorter duration of treatment. A shorter duration of treatment also led to higher satisfactory rates, which might be attributable to age at initiation, individual moldability, and treatment compliance. Complications were minor in all articles. Recurrence rate was low and mostly concerned prominent ears, which proved to be the most difficult to correct deformity as well. Malformations, however, were even more difficult to treat than deformations. Our analysis shows ear molding to be a successful treatment method for ear anomalies with a preference for early diagnosis and treatment.

Efficacy and Timing of Neonatal Ear Correction Molding

BACKGROUND AND AIM

Given the incidence of congenital auricular anomalies varies racially, this study aimed to investigate the efficacy and timing of ear correction molding in infants with auricular anomalies.

MATERIALS AND METHODS

A total of 141 auricular anomalies of 100 infants less than 4 months of age were treated using the Earlimn molding system. Treatment outcomes were graded (three categories) in terms of auricular morphology. The efficacies and outcomes of modeling were evaluated in infants according to age and anomaly type.

RESULTS

The mean age at which correction was initiated was 35.13 days of life, and the average treatment duration was 17.81 days. Of all anomalies, 86% were corrected. Both deformations and certain malformations were satisfactorily corrected. The outcomes of children with conchal crura and mixed anomalies were relatively poor. Although no differences in treatment efficiency were evident among the three age groups, infants < 3 weeks old required shorter treatment courses than those > 6 weeks old. The only complications were mild skin ulcers.

CONCLUSIONS

Ear correction molding is remarkably effective for infants with auricular deformations/malformations. Molding efficacy depends on the type of anomaly. Initiation of molding at less than 6 weeks of age is essential to minimize treatment duration.
