Forehead flag flap.

We present a modification of the Okada and Maruyama's flap for forehead reconstruction, based solely on the supratrochlear vessels. The flap is raised extra-periosteally but in the area of the pedicle the periosteum is included in the flap to protect the vessels. The flap is advanced and rotated to cover full thickness defects on the contralateral hemi-forehead, like a flag on its flagpole. We have treated six patients with large malignant tumours of the forehead which required excision including the periosteum. The flap survived in all cases and no necrosis was observed in any. The main advantage of this flap is that it is relatively straightforward to raise, being a good solution in selected cases (elderly patients). The main disadvantages of this flap are that the supraorbital nerve is sacrificed and some distortion of the eyebrows occurs.
