Injury to the Facial Nerve Associated with the Use of a Disposable Nerve Stimulator

Abstract

Clinical observations and experimental data from this study support the thesis that the disposable Weck nerve locator/stimulator may induce neural damage. This potential damage may cause at least a temporary paresis. Although more study is required to better document the method, degree, and factors influencing injury, we believe that enough evidence is present to induce caution and warrant further study. We recommend that the stimulators be used with caution on the lowest setting possible and with as little contact with the nerve as possible.
