Abstract

Intra-operative SEP monitoring was performed in nine patients with cervical syringomyelia undergoing myelotomy and syringo-endoscopy. Several cortical and subcortical SEP components were evaluated. Pathological latency shifts of brain stem P14 were seen in two patients; other SEP components did not worsen nor recover intra-operatively. The clinical and pathophysiological significance of the data is briefly discussed.
