What Are The Potential Complications From A Forehead Cranioplasty With Kryptonite?

Q:  Dr. Eppley, can we practice an onlay cranioplasty with tkryptonite in the front of the skull and end up having a smooth forehead shape? Are the most common complications of kryptonite cranioplasty surface irregular and a palpable demarcation between the bone of the skull and the kryptonite in certain areas? What is the likelihood that a second would be needed to smooth the surface of the kryptonite? If the demarcation between the bone of the skull and the kryptonite is especially annoying on the forehead after surgery, what is the solution?

A:  In answer to our specific questions:

1) It will not likely create a smooth contour.  

2) What you have mentioned are the two aesthetic complications with an injectable or minimal incision kryptonite cranioplasty.

3) It can be done endoscopically (small scalp incisions) with a long handled rasp.

4) It will be and it is corrected secondarily as mentioned in #3.
