Textural differences
When an advancement flap is utilized to repair a defect, the advanced tissue typically
has an excellent color and texture match to the native skin. However, for defects bridging cosmetic subunits, advancement flaps may fill the defect with skin of a different texture, hair density, or thickness. In such cases, it may be helpful to thin the dermal component of the flap to match the thickness of the skin surrounding the defect.
CONCLUSIONS
Advancement flaps represent a versatile workhorse reconstructive approach, particularly for defects close to free margins. Appropriate design and execution require mastery of several key concepts, including appreciating the direction of the primary tension vector; handling the displaced standing cones; balancing local factors that impact flap vascularity; and deciding when to alter the defect prior to tissue advancement. Thoughtful incorporation of these concepts, while keeping in mind the fundamental principles of flap dynamics, results in predictably reliable outcomes.
