The advantages of domestic ear molding system in molding bilateral neonatal congenital auricular deformities

Background There are different types of ear molding devices on the market. However, due to high cost, the wide application of the ear molding is hindered, especially for children with bilateral congenital auricular deformities (CAD). This study is designed to correct the bilateral CAD with the flexible use of Chinese domestic ear molding system. Methods Newborns diagnosed with bilateral CAD were recruited in our hospital from September 2020 to October 2021. For each subject, one ear wore a set of domestic ear molding system, while the contralateral ear used only matching Retractor and Antihelix Former. Medical charts were reviewed to collect data on the types of CAD, the incidence of complications, the initiation and duration of treatment, as well as the satisfaction after treatment. Treatment outcomes were graded into three levels: excellent, good, and poor, according to the improvement of auricular morphology evaluated by both doctors and parents, respectively. Results A total of 16 infants (32 ears) were treated with the Chinese domestic ear molding system, which contains 4 cases with Stahl’s ear (8 ears), 5 cases with Helical rim deformity (10 ears), 3 cases with Cup ear (6 ears), 4 cases with Lop ear (8 ears). All infants accomplished the correction completely. Both parents and doctors were satisfied with the outcomes. No obvious complication was observed. Conclusions Ear molding is an effective nonsurgical treatment for CAD. Molding with Retractor and Antihelix Former is simple and effective. Domestic ear molding system can be flexibly used in correcting bilateral CAD. With this approach, infants with bilateral CAD will benefit more in the near future.
