INTRODUCTION: Intraoperative electrophysiological studies are increasingly used in spinal surgery. However, its use in myelomeningocele (MMC) surgery is still not widespread. The aim of this study was to present our experience in neural placode (NP) and nerve root stimulations in newborns with open MMC.
METHODS: Eight newborns underwent surgical treatment for thoracolumbar and lumbosacral MMCs. Intraoperative neuromonitoring including free-running electromyography and stimulation of NP, nerve roots, and spinal cord were performed in all cases. Stimulation sites and intensities and distal response's amplitudes and latencies were recorded.
RESULTS: Five patients had thoracolumbar and 3 patients had lumbosacral MMC. Two patients had no movements at the lower extremities while the other had some movements. No response on the lower extremities was obtained in only 1 patient. Responses from the nerve root stimulations were more robust and significant than the placode stimulations.
CONCLUSIONS: It is clear that the NP and nerve roots originating from the placode are mostly functional and should be preserved during the surgery. Intraoperative neuromonitoring and direct stimulation should be performed during the MMC repair in order to obtain a better neurological outcome.
