Objectives: Cochlear implantation (CI) is a safe and effective procedure for hearing rehabilitation, with few major complications. Device exposure or extrusion is a rare but major complication that often necessitates explantation due to wound dehiscence or infection. The objective of this report is to present a previously undescribed case in which the cochlear implant grounding wire extruded in 16-month-old patient 3 months post-operatively in the absence of trauma or infection. Methods: We reviewed the case report and the pertinent literature. Results: A 16-month old male suffered extrusion of his left cochlear implant grounding wire without known etiology 86 days post-operatively after bilateral cochlear implantation. The patient was taken for surgery, and the electrode was reimplanted without complication followed by 48 hours of prophylactic intravenous antibiotics. Nine month follow up revealed the implant functioning appropriately, with no further major complications encountered. Conclusion: We present this unique case to demonstrate that a cochlear implant grounding wire extrusion is not necessarily an indication for explantation in the absence of infection.
