Objective
Ear molding for treatment of congenital ear deformities is effective and safe, so the use of ear correction devices is increasing in newborns. But there is no unified standard grading for evaluation the outcomes of ear molding.
Methods
We investigated how each study evaluated the effectiveness after ear molding. The search encompassed English databases and full text except case study including Pubmed from January 2016 to April 2026. Key search terms included “ear molding, auricular deformities, ear correction, ear devices, non-surgical ear correction, EarWell and other related keywords.
Results
A total of 22 studies about ear molding were eligible. 6 studies use ‘effective rate’ and 3 studies use from 1 to 5 scores to evaluate the result of ear molding. The rest of 13 studies use 3 or more things of Excellent, Good, Fair and Poor.
Conclusion
It is expected that various ear correction devices will be developed and applied. To assess the corrective effect, we suggest standardizing grades the assessment of ear molding to ‘Excellent/Good/Poor’ and refer to it as “Nathan`s grades of newborn`s ear molding”.
