CEREBROSPINAL-FLUID SPACES BEFORE AND AFTER INFANT FRONTO-ORBITAL ADVANCEMENT IN UNILATERAL CORONAL CRANIOSYNOSTOSIS

Computed tomographic scan-based examination of the cerebrospinal fluid -filled spaces before and after fronto-orbital advancement in infants with unilateral coronal synostosis was performed. In infants who had n ot undergone surgery, pronounced compression of the ipsilateral fronta l brain substance, frontal subarachnoid space, and frontal horn of the lateral ventricle were evident, with deviation of the interhemisphere fissure. After infant fronto-orbital advancement, frontal dead-space is obliterated early by expansion of the frontal subarachnoid space. A symmetries in the brain substance lateral ventricle and interhemispher ic fissure are slower to adapt and may be persistent some years later.
