With implants on your forehead, are the only risks involved infections?

Hello,Often we'll directly shape the bone of the forehead so that you have the shape you want without needing any implants.  I do that about 3-4 times per week for people and we get excellent results.Without a photo it's hard to know what you need, but that is an option.Jeff Spiegel

I would only recommend these types of implants in cases where you have a significant deformity, such as one cause by a severe injury.  Otherwise, stay away from them.

Forehead augmentation can be accomplished with implants as you suggest, and they can be custom made from 3D CAD models off of a facial CT scan.  Risks include infection, numbness or other nerve damage, bleeding, bruising, scarring, etc.  The incision to place larger implants is usually ear to ear across the top of the head.  Alternatively, you can use bone filler that either comes in a paste or putty.  This can be placed with the same type of incision or sometimes depending on the area and volume, can be placed through small endoscopic incisions back behind the hair line.  Any filler in the face around the eyes caries a very low risk of blindness, but this can be mitigated (no studies to back this up yet) by use of blunt tip cannulas.  If the tip is blunt, the chance of injecting filler into a blood vessel that then back flows to the ophthalmic artery is reduced.  You have quite a few choices and the approach should be tailored to your facial structure and desired improvements.  See someone who has experience with the various techniques and only move forward when you find someone you are comfortable with.  All the best!
