Forehead Feminization

Male foreheads differ from female foreheads by having a bony prominence (supra-orbital ridge or brow bone) over the eyebrows. In other words, the bone over the eye sockets projects farther forward than the bone in female foreheads. Additionally, the forehead above this prominence is usually flatter or occasionally tilted backwards compared to the female forehead, which is usually more vertical or even slightly rounded or convex. Located behind these ridges are the frontal sinuses. However, they are absent in 5% of the population and only on one side in 15%.

To reduce the brow bossing, an incision is made in the scalp which allows the forehead skin to be elevated for access to this area. It is then burred down with an electric drill. In patients with very flat or posteriorly directed foreheads, a synthetic material (methyl methacrylate) is occasionally used to produce the more feminine, rounded contour. And, finally, if the frontal sinuses are very enlarged, the anterior wall may, at times, have to be set back.
