A series of 314 posterior fossa duraplasties in children were performed at the Department of Neurosurgery, Hradec Králové, over the past 33 years. Computed tomographic (CT) imaging was used to compare the healing of various kinds of collagenic dural substitutes - allogeneic fascia lata, allogeneic dura mater and xenogeneic pericardium. Early (8 days to 3 months following surgery) and late (1-18 years following surgery) axial CT scans with sagittal reconstruction for duraplasty in 55 children were evaluated. In early postoperative CT scans, epidural collections of cerebrospinal fluid, sanguinolent liquid or haematoma and/or pseudocysts or pseudomeningoceles appeared. In late CT follow-up, calcifications and ossifications in the 'suboccipital coverings complex' (SCC) gradually developed and pseudocysts or pseudomeningoceles rarely persisted. It is concluded, on the basis of perioperative, clinical, and CT examinations, that posterior fossa duraplasties in children formed an important anatomical barrier and regardless of the type of graft had a favourable outcome; CT was shown to be a suitable method for the demonstration of dural grafts at the site of craniectomies.
