What intraoperative monitoring was used in the laminoplasty/laminectomy in OPD7390?

During spinal decompression like laminoplasty or laminectomy, the goal is to keep the spinal cord functioning while removing compression. Somatosensory evoked potentials monitor the sensory pathways that travel through the dorsal columns of the spinal cord. By constantly stimulating peripheral nerves (for example, a limb nerves) and recording the brain’s or sensory cortex responses, this method provides real-time feedback on whether the spinal cord’s sensory tracts are intact. If the SSEP signals change—such as a drop in amplitude or a change in latency—the surgeon can quickly adjust the procedure to protect the cord, for instance by reducing pressure, reassessing blood flow, or loosening hardware. This makes SSEPs a practical choice for spinal decompression, because they directly reflect the functional status of the spinal cord itself. In contrast, EEG measures global brain activity and isn’t specific to the spinal cord; EMG monitors muscle activity and nerve roots, which can alert to peripheral nerve irritation but not reliably detect central spinal cord injury. Thus, for monitoring spinal cord integrity during laminoplasty/laminectomy, somatosensory evoked potentials are the most informative option.
