Summary
This study explores a new radial forearm flap dissection starting from the radial side. This approach offers early access to critical vessels and nerves, enhancing reconstructive surgery safety and efficacy.
Area of Science:
- Anatomy
- Surgical Technique
- Reconstructive Surgery
Background:
- The radial forearm flap is a vital component in reconstructive surgery.
- Traditional dissection begins from the ulnar side.
Purpose of the Study:
- To evaluate an alternative radial forearm flap dissection initiated from the radial side.
- To assess the feasibility, safety, and efficacy of this novel approach.
Main Methods:
- Anatomical dissection of a formalin-fixed human specimen.
- Flap designed around the radial artery.
- Dissection initiated radially, followed by ulnar-side dissection.
Main Results:
- Early access to the distal radial artery and venae comitantes was achieved.
- Preservation of the superficial radial nerve and lateral antebrachial cutaneous nerve was facilitated.
- Identification and preservation of tendons were successful.
Conclusions:
- Initiating radial forearm flap dissection from the radial side provides early vascular control and precise neural/vascular preservation.
- This method shows procedural benefits for reconstructive surgery.
- Further clinical studies are needed to confirm efficacy in live surgical procedures.
