Reduction of the prominent brow bones can be done by two basic techniques and is done for different reasons/patient populations. (e.g., prominent male brow, part of facial feminization surgeries) The type of patient and the degree of brow bossing will determine the best surgical technique. In some cases augmentation of the forehead above the brow bone can also help reduce its appearance, either done alone or in combination with actual brow bone reduction.

Brow Bone Reduction by Burring X-Ray Dr Barry Eppley IndianapolisThe thickness of the brow bones (technically the thickness of the anterior bony wall of the frontal sinus) will largely determine the surgical technique of choice. When combined with the degree of brow prominence needed, the choice of reduction technique will be clear. The best way to determine the thickness of the anterior bony wall is a CT scan. This will allow one to measure the thickness of the anterior wall the whole way across the width of the brow bossing. A side to side assessment is very important and can not be judged just based on a lateral plain skull film alone. (better than no x-ray at all however)

Brow Bone Rerduction by Burring Dr Barry Eppley Indianapolis Preoperative X-RayIf the anterior wall of the brow bone is thick enough (usually 5mms or greater), a burring technique for reduction can be used. This is the simplest brow bone reduction technique and allows for the best degree of reshaping with a low risk of frontal sinus exposure. It is a technique much more commonly used in women than men because the degree of brow  bone reduction needed is often less. But is some men with adequate bone thickness, burring alone may be adequate for the central and adjoining medial brow areas where men have the greatest protrusions.

Male Brow Bone Reduction Mid Forehead Approach Dr Barry Eppley IndianapolisThe problem with brow bone reduction in men is usually one of access. While a full coronal scalp or frontal hairline incision is typically used, such incisions in men often poses aesthetic challenges based on their hairline location, density and pattern. One incisional option for a few select men is a horizontal forehead wrinkle. (if they have a fairly prominent one.

Mid-Forehead Approach for Brow Bone Reduction by Burring Dr Barry Eppley IndianapolisDirect Brow Bone Reduction by Burring with Supraorbital Nerve Isolation Dr Barry Eppley IndianapolisThrough a central horizontal forehead wrinkle incision, the brow bones can be easily accessed. One important feature of this forehead incision is not to make it too far lateral to avoid transecting the supraorbital nerves and causing permanent forehead and anterior scalp numbness. This allows a burring reduction technique to be done under direct vision where the exit of the supraorbital nerves can be seen and protected. Reduction can be aggressively done in the glabellar and medial half of the supraorbital rims with relative ease.

The central forehead incision for male brow bone reduction requires a thick anterior frontal sinus wall, an evident horizontal forehead wrinkle and an aesthetic reduction amount that does not exceed the bone wall thickness.
