In a delayed flap technique, when is flap mobilization typically performed?

• A. 14 days
• B. 7 days
• C. 21 days
• D. 28 days

Answer: (A)

In a delayed flap, the tissue is first given time to develop a richer blood supply before it is moved into place. The timing hinges on when enough neovascularization and perfusion have occurred to support flap survival during advancement. Mobilizing the flap around two weeks after the delay stage provides a balance: by this point, new circulating vessels have formed well enough to reduce the risk of partial flap necrosis, while tissue remains pliable enough to allow safe movement and inset. If you move it too early, the flap may not have adequate perfusion and can fail; if you wait too long, tissue contraction and stiffness can complicate mobilization and healing. Therefore, mobilization at roughly two weeks (about 14 days) is the typical, best-tolerated interval.
