Evoked cervical endoscopy

Details and patient eligibility

About

Cervical foraminotomy is used to treat recalcitrant foraminal stenosis in the cervical region. This foraminotomy can be performed under endoscopy. The irrigation pressure used to allow adequate visualization of the anatomical structures is usually between 40 and 50 mmHg. This pressure has no adverse effect intraoperatively on motor evoked potentials but its effect on somesthetic evoked potentials has not yet been studied. The purpose of this study is to validate the absence of disruption of somatosensory evoked potentials by endoscopic cervical foraminotomy
