When performing a rhomboid flap, around what angle must the pivot be maintained?

• A. 60 degrees
• B. 90 degrees
• C. 120 degrees
• D. 180 degrees

Answer: (C)

In the context of a rhomboid flap, maintaining a pivot angle of approximately 120 degrees is essential for several reasons. A rhomboid flap is designed to rotate around a central point to achieve optimal tissue coverage over a defect while preserving the surrounding blood supply. By maintaining this pivot angle, the vascular supply that nourishes the flap remains intact, ensuring viability following the rotation. This angle allows for the appropriate lateral movement of the flap while still supporting its base, reducing tension on the wound edges and promoting better healing. If the angle deviates significantly from 120 degrees, it could compromise blood flow and ultimately the survival of the flap. Understanding this precise angle is crucial for successful flap design in reconstructive surgery.
