Summary
The Tranquilli-Leali and Atasoy volar V-Y advancement flaps have distinct surgical dissections and unique blood supplies, crucial for fingertip amputation reconstruction. This study clarifies their anatomical differences.
Area of Science:
- Anatomy
- Microsurgery
- Plastic Surgery
Background:
- Tranquilli-Leali and Atasoy volar V-Y advancement flaps are standard for fingertip reconstruction.
- Literature descriptions of their surgical dissection and blood supply are often unclear.
- This study clarifies anatomical differences and vascular supply.
Purpose of the Study:
- To differentiate the Tranquilli-Leali and Atasoy volar V-Y advancement flaps.
- To elucidate the distinct blood supply of each flap.
- To provide anatomical clarity for fingertip reconstruction.
Main Methods:
- Dissection of 16 fresh cadaveric fingers (8 Tranquilli-Leali, 8 Atasoy).
- Mapping of arterial blood supply using injectable blue resin.
- Comprehensive literature review.
Main Results:
- Tranquilli-Leali flaps: Supplied by anastomoses between palmar digital arteries and dorsal nail-bed arcades via the fibro-osseous hiatus.
- Atasoy flaps: Perfusion solely through terminal branches of the palmar digital arteries.
- Distinct vascular patterns identified for each flap type.
Conclusions:
- Tranquilli-Leali and Atasoy flaps differ significantly in dissection technique and vascular supply.
- Understanding these anatomical distinctions is vital for successful fingertip amputation reconstruction.
- This cadaveric and literature-based study clarifies specific vascular supply to each flap.
