Summary
Microsurgical thumb reconstruction using great toe flaps achieved 100% survival and excellent functional and aesthetic outcomes in 43 patients. This technique minimizes scarring for improved thumb appearance and function.
Area of Science:
- Microsurgery
- Plastic Surgery
- Reconstructive Surgery
Background:
- Thumb defects can significantly impair hand function and aesthetics.
- Microsurgical reconstruction offers a potential solution for complex thumb defects.
Purpose of the Study:
- To evaluate the efficacy of microsurgical reconstruction for thumb defects.
- To assess flap survival and functional outcomes in reconstructed thumbs.
Main Methods:
- Microsurgical techniques were employed in 43 patients for thumb reconstruction.
- Great toe and adjacent structures were used as donor sites.
- Adventitia removal from vascular pedicles and subcutaneous tunneling minimized scarring.
- Nail width and pulp volume were matched to the defect pre-transfer.
Main Results:
- Achieved 100% flap survival in all reconstructed thumbs.
- Demonstrated functional improvement with near-normal appearance post-reconstruction.
- Subcutaneous tunneling and meticulous donor site selection minimized scar formation.
Conclusions:
- Microsurgical reconstruction using great toe flaps is a highly effective method for thumb defects.
- The technique yields excellent functional and aesthetic results with high flap survival.
- Careful donor site selection and surgical technique are crucial for optimal outcomes.
