Craniosynostosis is a condition in which one or more of the fibrous sutures in an infant skull prematurely fuses by turning into bone (ossification), thereby changing the growth pattern of the skull. Because the skull cannot expand perpendicular to the fused suture, it compensates by growing more in the direction parallel to the closed sutures. The fusion of this suture causes a certain change in the shape of the skull; a deformity of the skull. Sometimes the resulting growth pattern provides the necessary space for the growing brain, but results in an abnormal head shape and abnormal facial features.
There are four types of craniosynostosis:
Craniosynostosis occurs in one in 2000 births. Craniosynostosis is part of a syndrome in 15 to 40% of the patients, but it usually occurs as an isolated condition.
Treating craniosynostosis usually involves surgery to separate the fused bones. If there's no underlying brain abnormality, the surgery allows baby’s brain adequate space to grow and develop. The primary goal in surgical intervention is to allow normal cranial vault development to occur. The few basic elements involved in the surgical intervention aimed at normalization of the cranial vault include: minimization of blood loss and the avoidance of the use of titanium plates in the fixation of the skull.
The ongoing researches in US on Craniosynostosis include: The Impact of Insurance, Race, and Ethnicity on Age at Surgical Intervention among Children with Nonsyndromic Craniosynostosis, Perioperative complications associated with intracranial procedures in patients with nonsyndromic single-suture craniosynostosis, Craniosynostosis with wormian bone, bowing of the long bones, unilateral short femur, and focal fibula deficiency.
