Intra-parenchyma Pneumocephalus: a Complication of Cochlear Implant

Objective: We report an extremely rare case of pneumocephalus after cochlear implantation. Method: Case report and a review of the world literature on pneumocephalus after cochlear implantation. Results: We present a case of uneventful cochlear implantation in a patient with nasal polyposis. Pos -operative nose blowing resulted in subcutaneous emphysema pneumocephale presenting five weeks post surgery. This resolved on conservative therapy, and the patient went on to use her implant successfully. Conclusion: To our knowledge this is the first report in the world literature of delayed onset as well as asymptomatic pneumocephalus after cochlear implantation
