Electrostatic Discharge (ESD) as a Cause of Facial Nerve Stimulation After Cochlear Implantation: A Case Report

Abstract

Objective: To discuss persistent facial nerve stimulation (FNS) related to repeated electrostatic discharge (ESD) shock following cochlear implantation. Methods: Single case report with literature review. Results: FNS 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 seconds of processor attachment caused a significant decrease in the patient’s quality of life, requiring subsequent re-implantation with full resolution. Conclusions: FNS 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.
