Summary
A novel hyaluronic acid injection technique offers a simple and effective solution for correcting prominent ear deformities. This minimally invasive approach significantly improves ear shape and patient satisfaction with minimal complications.
Area of Science:
- Plastic Surgery
- Dermatology
- Aesthetic Medicine
Background:
- Lying-ear deformity, characterized by excessive backward auricle bending and prominent antihelix, traditionally requires complex surgical intervention.
- Surgical correction often involves prolonged recovery periods and specialized surgical expertise.
- There is a need for less invasive and more accessible treatment options for ear deformities.
Purpose of the Study:
- To evaluate the efficacy and safety of a simple hyaluronic acid (HA) injection technique for correcting lying-ear deformity.
- To assess the impact of HA injections on auricle shape and patient-reported aesthetic outcomes.
- To compare postoperative measurements with pre-treatment values and analyze patient satisfaction.
Main Methods:
- A prospective study involving 20 patients with lying-ear deformity who underwent treatment with multiple HA injections.
- Postoperative outcomes were evaluated using objective measurements (auriculocephalic angle, conchoscaphal angle) and subjective patient grading via a visual analog scale (VAS).
- Interrater reliability for VAS scores was assessed using intraclass correlation coefficients (ICCs).
Main Results:
- Significant improvements were observed in auriculocephalic angle (25.11° to 32.72°) and conchoscaphal angle (87.69° to 95.94°).
- Patient-reported outcomes showed a substantial increase in VAS scores from 4.40 to 8.57, indicating high satisfaction.
- No serious complications such as infection or embolism were reported; fair to good interrater reliability was noted for VAS scores.
Conclusions:
- Hyaluronic acid injection is a safe, effective, and minimally invasive method for correcting lying-ear deformities.
- This technique significantly enhances outer ear shape and improves perceived facial aesthetics, leading to excellent patient satisfaction.
- The proposed injection protocol provides a valuable alternative to traditional surgical interventions for prominent ear correction.
