Summary
This study presents a new single-stage autologous ear reconstruction technique for microtia, significantly reducing treatment time and improving patient satisfaction with a low complication rate.
Area of Science:
- Plastic Surgery
- Otolaryngology
- Regenerative Medicine
Background:
- Traditional autologous ear reconstruction is a multi-stage process, often requiring 2-4 stages or skin expansion.
- A shortened treatment period for ear reconstruction would significantly benefit patients.
Purpose of the Study:
- To introduce a novel, single-stage autologous ear reconstruction technique.
- To enhance safety and outcomes in ear reconstruction surgery.
- To reconstruct a complete ear contour with postauricular sulcus in one stage.
Main Methods:
- Preoperative design of postauricular skin flap.
- Elevation of a super-thin postauricular skin flap.
- Fabrication of a modified three-layer framework, postauricular fascial flap elevation, skin grafting, and earlobe transposition.
Main Results:
- 245 patients with lobule-type microtia underwent reconstruction between June 2020 and October 2023.
- 91% patient and family satisfaction reported.
- Overall complication rate was 7.5% with follow-up ranging from 6 to 39 months.
Conclusions:
- The modified first-stage autologous ear reconstruction technique offers safe and satisfactory outcomes.
- This approach is effective for lobule-type microtia.
- The technique successfully reconstructs the ear contour in a single stage.
