Soonest you can move a flap in a delayed flap technique?

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

Answer: (B)

In a delayed flap, the tissue is preconditioned to develop its own increased blood supply from the bed before final transfer. After the delay, the flap undergoes neovascularization and improved arterial inflow and venous outflow, which typically matures over about two weeks. By around fourteen days, the flap usually has enough perfusion to survive when moved, making this the earliest safe time to transfer in many cases. Transferring earlier, such as around seven days, risks insufficient perfusion and partial necrosis because the new blood supply hasn’t fully developed yet. Waiting longer than about two weeks generally doesn’t add much benefit and can complicate healing.
