Electrostatic Discharge (ESD) as a Cause of Facial Nerve Stimulation After Cochlear Implantation: A Case Report.
Abstract
OBJECTIVE\nTo discuss persistent facial nerve stimulation (FNS) related to repeated electrostatic discharge (ESD) shock following cochlear implantation.\n\n\nMETHODS\nSingle case report with literature review.\n\n\nRESULTS\nFNS is a feared complication after cochlear implantation, occurring in approximately 7% of cases, with most patients having anatomic abnormalities. The presented case has no anatomical abnormalities but reported frequent environmental static shock. FNS during the first 1 to 3\u2009seconds of processor attachment caused a significant decrease in the patient s quality of life, requiring subsequent re-implantation with full resolution.\n\n\nCONCLUSIONS\nFNS is a complication of cochlear implantation that can cause a great deal of distress and discomfort. Frequent electrostatic discharge (ESD) contributed to device malfunctioning and FNS in a patient with otherwise normal anatomy and should be avoided if possible.
