Background: Somatosensory evoked potentials test is a functional assessment for the sensory pathways in the dorsal column of the spinal cord. It can be used for compression diagnosis in cervical disc prolapse. Objective: To compare the SEP values in cervical disc prolapse patients, preoperatively and postoperatively and to correlate these with the clinical improvement. Methods: Twenty cervical disc patients, indicated for surgery were included in this study. All were evaluated clinically and by SEPs before and 1st, 3rd and 6th month after surgery. Results: The statistical data of N14 wave latency originating from the nuclei of the dorsal column of the medulla spinalis has statistical significance (p<0.05). Conclusion: This study concluded that SEPs test is an accurate and prognostic indicator for dorsal column dysfunction resulting from compression, especially during the postoperative period.
