OBJECTIVES: @entity3541 is a rare but devastating complication of cochlear implant surgery. The aims of the study were to define the incidence of @entity3541 in our series and understand possible mechanisms of injury. STUDY DESIGN: Retrospective chart review and case reports. METHODS: Charts were reviewed of all 705 @entity1 implanted between 1980 and 2002 at the authors' institutions to identify those with postoperative @entity425 and determine incidence. For @entity1 with @entity425 , onset, degree, and timing of @entity912 were noted; clinical findings were correlated to operative report findings. The method of treatment was noted, and the final facial nerve function outcome was recorded. RESULTS: Five @entity1 (one @entity1 and four adults) were found to have postoperative @entity425 , for an incidence of 0.71%. This complication was delayed in all cases, ranging from 18 hours to 19 days postoperatively. All @entity1 were treated with @entity230 or @entity230 combined with antiviral medication, and all ultimately recovered normal facial function. CONCLUSIONS: In the study series, the incidence of @entity3541 following cochlear implant surgery was 0.71%. Possible mechanisms of injury included @entity130 and viral reactivation. All @entity1 presented with a delayed @entity3541 and did recover normal facial nerve function.
