Summary
This study introduces a novel surgeon-engineer approach for customized polyetheretherketone (PEEK) implants to correct paranasal concavity. The method significantly improved facial aesthetics and patient satisfaction, offering an effective solution for this aging concern.
Area of Science:
- Plastic Surgery
- Biomaterials Engineering
- Facial Aesthetics
Background:
- Paranasal concavity contributes to a prematurely aged facial profile, particularly in East Asian females.
- Customized polyetheretherketone (PEEK) implants offer a solution, but design challenges persist.
- An optimized interdisciplinary approach integrating clinical and engineering expertise is needed.
Purpose of the Study:
- To introduce a novel design strategy for customized PEEK implants in paranasal augmentation.
- To investigate the clinical outcomes of this interdisciplinary approach.
Main Methods:
- Enrolled 36 female patients with bilateral paranasal concavity.
- Established a surgeon-engineer collaboration workflow for implant design (position, size, thickness, screw channel, surface morphology).
- Evaluated outcomes using objective quantitative measurements and subjective patient questionnaires.
Main Results:
- Significant reduction in paranasal concavity depth (e.g., right side from 5.45 mm to 1.64 mm).
- Statistically significant increase in nasolabial angle (from 90.49° to 95.33°).
- High patient satisfaction (83.33% for aesthetic improvement) and confidence enhancement (72.22%).
Conclusions:
- The novel surgeon-engineer collaborative design strategy for PEEK implants is effective for paranasal concavity correction.
- This interdisciplinary approach achieves satisfactory aesthetic enhancement.
- The integration of clinical expertise and engineering precision is crucial for optimal outcomes.
