The hemifrontal flap is an efficient way of reconstructing large unilateral defects that involve the hemiforehead. Six patients had their foreheads reconstructed after the excision of neglected tumours in the frontal region. The flap was designed to provide adequate repair of large defects including the periosteum. The width of the flap above the eyebrow is almost equal to the vertical height of the forehead in the midline. Efficient reconstruction of the primary defect including surface and depth was achieved in all patients. There were no complications with the viability of the flap. The hairline and the line of the eyebrows were preserved in their original sites, with no alteration in the aesthetic landmarks of the forehead in 3 cases, where there was no invasion of tumour.
