Summary
This study introduces a novel prefabricated free flap technique for eyelid reconstruction using the contralateral lower eyelid. This method demonstrates successful long-term perfusion and tissue viability for severe soft-tissue trauma repair.
Area of Science:
- Ophthalmology
- Plastic Surgery
- Microsurgery
Background:
- Severe soft-tissue trauma to the eyelids presents significant reconstructive challenges.
- Existing methods for eyelid reconstruction may have limitations in achieving optimal functional and aesthetic outcomes.
Purpose of the Study:
- To evaluate the efficacy of a novel prefabricated free flap technique for eyelid reconstruction.
- To assess the viability, perfusion, and long-term outcomes of flaps created from the contralateral lower eyelid.
Main Methods:
- A prefabricated free flap was created from the contralateral lower eyelid in a rabbit model.
- The flap was tunneled and delayed before transfer to reconstruct full-thickness upper eyelid defects.
- Vascular patency and perfusion were assessed using Microfil injection and long-term follow-up.
Main Results:
- Prefabricated free flaps demonstrated long-term patency and full-thickness perfusion from the neopedicle.
- Flaps maintained size, shape, and accessory skin appendages superiorly compared to control grafts.
- Successful reconstruction of 50% full-thickness eyelid defects was achieved.
Conclusions:
- Prefabricated free flaps from the lower eyelid are a viable option for reconstructing eyelid defects.
- This technique offers a promising approach for managing severe eyelid trauma.
- A surgical technique for potential application in human subjects was proposed.
