Periosteal Flap
A reconstructive flap that incorporates periosteum to provide vascular supply and structural support for complex scalp and forehead defects.
Full Definition
A periosteal flap is a specialized reconstructive technique used in dermatologic surgery that includes the periosteal layer along with overlying tissues. This type of flap is particularly valuable for reconstruction of scalp and forehead defects where robust blood supply and structural integrity are essential. The periosteum provides excellent vascularity and helps ensure flap survival, especially in areas with limited soft tissue coverage. The technique is commonly employed when reconstructing defects over bony prominences or when additional structural support is needed for optimal cosmetic and functional outcomes.
Usage
Usage note: Distinguish from fascial flaps, which involve fascia but not periosteum. Commonly used in scalp reconstruction where bone exposure is a concern.
