Summary
Noninvasive ear molding effectively corrects auricular morphological deformities (AMD) with an 85% success rate. Early treatment initiation (≤7 days) and shorter wear times (≤28 days) significantly improve outcomes for ear deformities.
Area of Science:
- Plastic Surgery
- Pediatric Otolaryngology
- Biomedical Engineering
Background:
- Auricular morphological deformity (AMD) encompasses various conditions affecting ear shape.
- Noninvasive ear molding devices offer a potential treatment strategy for these deformities.
- Evaluating the long-term efficacy and clinical application of these devices is crucial.
Purpose of the Study:
- To systematically evaluate the clinical application and long-term efficacy of ear molding devices for AMD.
- To explore future treatment strategies for auricular morphological deformity.
- To analyze correction outcomes for different types of AMDs.
Main Methods:
- Retrospective collection of clinical data from 102 patients with AMDs treated between 2017 and 2022.
- Inclusion of patients who underwent noninvasive ear molding correction with over 3 years of follow-up.
- Detailed analysis of correction for prominent ear, cup ear, cryptotia, and lop ear, recording outcomes.
Main Results:
- An overall correction success rate of 85.29% was achieved.
- Age at treatment initiation and total wear time significantly influenced correction outcomes.
- Early treatment (≤7 days) and shorter wear time (≤28 days) were independently associated with better results. Only one case reported significant eczema.
Conclusions:
- Noninvasive ear molding demonstrates favorable long-term outcomes for auricular morphological deformities.
- Correction outcomes are comparable across different morphological types of AMD.
- Treatment success is primarily influenced by the age of initiation and total device wear time.
