I had a TBI when I was 6 years old and had plastic fitted into the back of my head to close it (cranioplasty). Some time ago however, I started getting some sudden pain (once I felt an electric current running through the back of my head; at age 40). After an MRI and CT Scan, it was found that I somehow developed a crack in the plastic part of my skull. I am told that it can heal as the bone has merged with the plastic. The pain is less frequent now but it still returns from time to time.
Has anybody had any problems with their cranioplasty becoming damaged over time? If so, how long did it take for it to heal? What sorts of material was your cranioplasty made of and what side effects did you have?
