Islanded perforator flaps offer superior outcomes for syndactyly release compared to traditional methods. This surgical technique, guided by Doppler ultrasound, improves function and aesthetics while minimizing complications in congenital hand deformities.
Area of Science:
- Hand Surgery
- Congenital Hand Deformities
- Microsurgery
Background:
- Syndactyly is a congenital hand deformity requiring surgical correction.
- Traditional dorsal rectangular flaps have limitations, including web creep and residual deformities.
- Islanded perforator-based flaps offer enhanced vascularization for improved surgical outcomes.
Purpose of the Study:
- To evaluate the efficacy of islanded perforator-based flaps for syndactyly release.
- To compare outcomes of islanded flaps versus traditional dorsal flaps.
- To assess the role of preoperative Doppler ultrasound in surgical planning.
Main Methods:
- Prospective observational study of 31 webspaces in 26 patients undergoing syndactyly release.
- Preoperative Doppler ultrasound for vascular mapping in 15 cases.
- Assessment of functional and aesthetic results using Withey score, Visual Analog Scale (VAS), and photographic analysis.
Main Results:
- Improved VAS scores post-surgery, particularly in younger patients and males.
- Islanded flaps showed better long-term VAS scores (1.9±0.83) than dorsal flaps (2.60±0.84).
- Significant improvement in scar quality and minimal complications with islanded perforator flaps.
Conclusions:
- Islanded perforator-based flaps are a promising alternative for syndactyly release.
- Doppler mapping enhances surgical precision and vascular safety.
- This technique yields superior functional and aesthetic results with reduced complications.
