How to Make a Do-It-Yourself Disposable Bite Guard Using Easily Available Materials to Prevent Tongue and Lip Injuries During Motor Evoked Potential Monitoring in Neurosurgery

摘要

We describe a do-it-yourself method of making a bite guard, using pairs of Foley catheters and surgical gloves to prevent tongue, lip, and other injuries during the monitoring of transcranially elicited motor evoked potential. We have used it in five cases, and have found that the hack is particularly cost-effective and reliable. We describe the technique here using multiple photographs.
