Craniosynostosis occurs in the infant skull when premature fusion of the segments of the skull takes place. This condition does not allow room for the brain to grow. It can result in an abnormal shaped head and, sometimes, distorted facial features. Craniosynostosis can affect sight and mental abilities. Surgery must be performed early to make room for growth, usually between six and twelve months of age and eliminate the possibility of brain damage and long-term effects. For a successful surgery, the physician must determine which and how much of the fusions to separate to accomplish the room necessary for normal development without going to extremes. A 3-D cranial model best demonstrates the actual portions of the skull and lines where the plates join. This visual hands-on tool aids in pre-planning surgery for the best results. A well-planned surgery takes less time to achieve desired results. Less time in the operating room leads to a shorter time in regaining normalcy, and also can save thousands of dollars.
