Abstract

This article shows that subdural gas can accumulate and alter upper-extremity SEPs in patients in the sitting position. Preservation of lower-extremity SEPs in the presence of such subdural air affirms the benignity of this condition. Intraoperative skull radiography can demonstrate subdural gas under the parietal electrodes and obviate a potentially dangerous alteration in standard surgical technique.
