Is Injectable Kryptonite Cranioplasty A Good Option for Plagiocephaly?
Q: Hi Dr. Eppley, my question is about the Kryptonite used on plagiocephaly. My 3 yr old son has plagiocephaly with a very flat head which is a little asymmetrical. I have been told that his head is still growing and changing and that it could improve, but I don’t think so. In the past year and a half it has actually gotten worse. I want to know with his head shape if Kryptonite could be a great option for when he gets a bit older. Also are there any side effects? Does it cause irritation of the skin rubbing on the Kryptonite? His head also has a bit of slopping and is more narrow towards the front of his head. I’ve attached photos. Also with the amount of Kryptonite, how much would you say for his case if he is a good candidate for the procedure. Thank you!
A: Injectable Kryptonite cranioplasty can be a good option in the treatment of plagiocephaly because it helps build out the flatter side of the skull through a minimal incision approach. It is an onlay cranioplasty technique that causes no irritation to the underlying bone or the overlying skin. The biggest risk of this cranioplasty method is some irregularities of the augmented area given that it is done without visible molding or contouring of the material. In looking at your son’s photos, I would estimate that the total amount of material needed is about 10 grams, at most 15 grams. The material does expand as it sets so less is always needed than one thinks.
A detailed description and pictures of your concerns allows for the most informed response.
