title: The prediction of CSF gusher in cochlear implants with inner ear abnormality.
abstract: CONCLUSIONS
  The incidence rate of the cerebrospinal fluid (CSF) gusher in cochlear implant with inner ear abnormality is 30%. Bony defect in the fundus of the internal acoustic meatus is most often responsible for the occurrence of CSF gusher. This feature of the CT scan can be used to predict the occurrence of a CSF gusher.
  
  
  OBJECTIVE
  To predict the occurrence of CSF gusher in cochlear implants with inner ear abnormality.
  
  
  METHODS
  This was a retrospective analysis of 442 patients with inner ear abnormality who underwent cochlear implantation from February 1998 to July 2011. The patients were reviewed for the findings on temporal high resolution computed tomography (HRCT) scans and the complication of CSF gusher in cochlear implantation.
  
  
  RESULTS
  Among the 422 cases, 134 (30%) suffered from the complication of CSF gusher during the operation. They were all found to have a bony defect in the fundus of the internal acoustic meatus on the CT scans.
