Multimodality evoked potentials (somatosensory and acoustic) have been recorded before surgery in children selected for surgical treatment for different kinds of craniostenosis and craniofacial stenosis. Evoked potentials were found to be deranged on at least one recording in 50% of cases, suggesting a significant incidence of neurophysiological alterations in these patients. No correlation was found between evoked potentials' derangements and clinical status, radiological findings, or different kinds of craniostenosis; moreover, a significant correlation was found between neurophysiological alterations and the age of the children. These preliminary data might define the possible role of neurophysiological tests in the presurgical evaluation of craniostenosis and craniofacial stenosis
