Craniosynostosis refers to the early (premature) fusion of the sutures of the bones of the skull.  Premature fusing of the sutures restricts and distorts the growth of the skull. These cranial growth restrictions often results in increased cranial pressure growth which can cause vision problems and impede intellectual development.  In addition, abnormal head shape is associated with low self-esteem and behavioral problems.  Correction of these deformities can relieve cranial pressure and in the long-term, improve the child's self-esteem.
