Abstract

Case:Transcranial electric stimulation motor-evoked potentials (tcMEPs) are the most sensitive technique in multimodality intraoperative neuromonitoring (IONM) for posterior spinal fusion (PSF). The presence of a cochlear implant (CI) is considered a contraindication to IONM because of theoretical risk of implant device and local tissue damage from voltages induced by tcMEPs. We present the case of a 10-year-old girl with CI who underwent successful PSF with tcMEP and monopolar electrocautery (MoEC) without perioperative complications or CI damage.Conclusion:With proper precautions, such as MoEC usage at a minimal voltage, motor-evoked potential monitoring can be safely performed in pediatric patients with CI undergoing PSF.
