When should a tongue flap be divided after its placement?

• A. 1 week
• B. 2-3 weeks
• C. 4-6 weeks
• D. Immediately after placement

Answer: (B)

A tongue flap is often used in reconstructive surgery, particularly for defects in the oral cavity, due to its rich blood supply and versatility. After the placement of a tongue flap, it is crucial to allow sufficient time for vascular pedicle integration and to promote healing at the recipient site. Dividing the flap too early can risk compromising its blood supply, leading to flap necrosis, which would defeat the purpose of the procedure. The timeframe of 2-3 weeks after placement is typically recommended because, during this period, the flap should have established a sufficient blood supply to sustain viability after division. This allows for the integration of the flap into the surrounding tissues at the recipient site while minimizing complications. In general, earlier division, such as immediately after placement or within the first week, does not allow enough time for this vascular integration, which can jeopardize both the flap itself and the surgical area it is meant to support. Conversely, delaying division beyond 3 weeks may also pose unnecessary risks such as fibrosis or difficulty in later separating the flap. Therefore, 2-3 weeks strikes the right balance, ensuring optimal outcomes for the surgical reconstruction.
