Summary
Site-specific incisions and radiotherapy significantly reduce keloid recurrence after ear reconstruction. This innovative approach improves patient satisfaction and aesthetic outcomes for auricular keloids.
Area of Science:
- Plastic Surgery
- Dermatology
- Oncology
Background:
- Auricular reconstruction patients face high keloid development risks.
- Traditional keloid excision incisions may not suit reconstructed ear biomechanics.
Purpose of the Study:
- To evaluate site-specific incisions combined with radiotherapy for auricular keloids.
- To assess recurrence rates and patient satisfaction post-treatment.
Main Methods:
- Retrospective cohort study of 86 patients (90 ears) with post-reconstruction auricular keloids.
- Keloid core removal surgery with site-specific incisions (earlobe, helix, crus of helix).
- Superficial low-dose radiotherapy (3 Gy/session x 4) administered 24-48 hours post-surgery.
Main Results:
- Reduced recurrence rate of 6.7% compared to traditional methods.
- High patient satisfaction rate of 92.2%.
- Significant improvement in Vancouver Scar Scale (VSS) scores (p < 0.05).
Conclusions:
- Site-specific incisions and postoperative radiotherapy effectively decrease keloid recurrence.
- This combined approach yields optimal functional and aesthetic results for reconstructed ear keloids.
