Reconstruction with Axial Pattern Flaps

1. Introduction
The axial pattern flap is a variant of the transposition flap. The nature of the blood supply accounts for its improved viability and wherever possible, a direct cutaneous artery should always be incorporated into a skin flap.

2. Definition
An axial pattern flap is a transposition flap which incorporates a direct cutaneous artery and vein or their branches into its base. This supplies the subdermal plexus within the skin flap.

3. Indications and use
Advantages of the axial pattern flap, compared to random-pattern subdermal plexus flaps include:
• Development of larger flaps is possible
• More consistent survival due to improved blood supply
• Less reliance on blood supply from the recipient wound
