AbstractThe authors present a review of their experience of cranioplasty in cases showing of skull defects. Forty recent case reports were retained out of a total of 125 cases and of these, 15 showed neurological deficiency prior to cranioplasty. In 7 out of these 15 cases cranioplasty appeared to have no effect, but in the 8 remaining cases, an improvement in the neurological condition was observed. In connection with these clinical observations, a recent study of a small group of patients with skull defects used the Xenon 133 inhalation method to investigate cerebral blood flow. In all cases these was a significant postoperative improvement in cerebral blood flow. The rate varying from 15 to 30% and this improvement was even observable in the case of small skull defects of the order of 10 cm2. The mechanism giving rise to such improvements is discussed; it may be related to cerebral hemodynamic normalization after skull restoration. The improvement in cerebral blood flow brought about by cranioplasty in all the cases studied suggests that this technique may be important not only for simple skull repair but also to improve neurological function.
