Outline
Text
Background: Severe hearing loss or deafness are complications of bacterial meningitis in up to 15%. In these cases an auditory rehabilitation by cochlear implant treatment is generally accepted. Early beginning obliteration of the cochlea can lead to a difficult or impossible electrode insertion, to get optimal results a full insertion is to be demanded.
Methods: Due to a retrospective analysis of patients with cochlear implant treatment because of deafness or severe hearing loss after bacterial meningitis in the years 2002-2006 the managment of the preoperative diagnostic and the intraoperativ treatment is described and examples are shown.
Results: With early diagnosis and a fast operative treatment a full electrode insertion was possible in all cases. In case of a beginning obliteration of the inner ear structures a simultan bilateral cochlear implant operation was performed. The MRI is superior to a CT Scan showing early obliteration of the labyrinth.
Conclusions: The diagnosis of bacterial meningitis must lead to an early hearing scan. In case of deafness or severe hearing loss specialiced centers are to be contacted to get a fast imaging of the inner ear structures. Beginning obliteration indicates a quick simultan bilateral cochlear implant treatment. Patients with milder hearing loss should be treated with hearing aids. Due to a possible progressive hearing loss further inspections are necessary.
