What Is The Best Method Or Material To Use For Forehead Augmentation?
Q: I’m a male in my thirties and I would like to have surgery to give my orbital rim and forehead a more masculine (protruding) appearance. I had a craniotomy 3 years ago which has left a dent on my forehead which I would like to eliminate. I understand that solid HA is more porous than the moldeable putty type which would allow tissue growth and ossification. I would like to know answers to the following questions. 1) In order to make my forehead more prominent would it be possible to use 3-D CT scan technology to customize a solid HA implant instead of using moldable HA paste? 2) Could the customized HA implant be made with an interior mesh to make it less brittle? 3) Would a customized HA implant in solid form be easier to work with than HA in paste? 4) Could using a solid HA implant present problems such as fluid accumulation, visible borders, migration or extrusion. I thank you for your time.
A: Thank you for your excellent and thoughtful cranioplasty questions. I can answer of your HA cranioplasty questions by saying that I really don’t use the HA pastes anymore. In their day they were state of the art and they were wonderfully moldeable, but they are brittle. This is no different that HA blocks or HA custom implants which actually are just as brittle and much harder to work with. The newest and more improved cranioplasty material is Kryptonite Bone Cement. It offers easy molding and shaping into the defect, sets up and gets just as hard as bone, and is truly porous (unlike most HAs which are not except the blocks) which allows tissue ingrowth. This is clearly the superior cranioplasty material and eliminates all of your stated concerns and questions.
Therefore, based on these working properties of Kryptonite, HA is no longer used and a 3-D CT scan model is not necessary beforehand since there is no advantage to making a pre-formed implant. (which is now a disadvantage and very costly)
I see no problems at all doing forehead and orbital rim augmentation and any contouring of a forehead indentation with Kryptonite Bone Cement through your existing scalp scar and open approach.
