What is the scarring like with brow bone reduction?

Brow bone reduction in the male. The scar initially won't show.  The incision is made in the existing hairline where. you have thick hair and if this area should become bald in  the future you will need hair transplants or the Fleming Mayer  flap for this. See a very experienced surgeon with these techniques. 

Thank you for your question. I suggest that you move forward and consult with a board certified facial plastic surgeon. It would be important for you to learn more about your desired outcome, and the procedures available to you.
Best wishes,

contouring the bone can be done endoscopically with a Stryker mini burr.  There still needs to be an access incision but in the hair bearing temple area it will be concealed--unless you plan to shave your head--then any incision no matter how short or where placed will be visible.  While I have personally never done this through an upper eyelid incision there may be others who can--make sure you're not the trial patient!

The incision for brow bone reduction is hidden by hair when it is made in the hairline using the Irregular Tricophytic Hairline Incision technique that we described many years ago. However it is very important that you be examined and your family history of male pattern baldness reviewed because with significant alopecia later in life that incision can become exposed which would be problematic for a man who does not have enough donor for hair replacement surgery.
