title: Straight versus modiolar hugging electrodes: does one perform better than the other?
abstract: OBJECTIVE
  To determine differences in speech perception outcomes for patients who received a CI422 and a Contour cochlear implant.
  
  
  METHODS
  Retrospective case review.
  
  
  METHODS
  Tertiary referral center.
  
  
  METHODS
  Thirty-two adults who underwent cochlear implantation.
  
  
  METHODS
  Cochlear implantation using a CI422 or Contour device.
  
  
  METHODS
  Bamford-Kowal-Bench (BKB) speech perception scores at 3 and 9 months after activation.
  
  
  RESULTS
  The mean BKB scores at 3 months for the CI422 device were 86.0% in quiet and 55.1% in noise. This compares with 86.0% in quiet and 62.3% in noise for the Contour device. At 9 months, the mean BKB scores were 85.9% in quiet and 67.1% in noise for the CI422 and 90.1% in quiet and 77.6% in noise for the Contour device. There was no statistically significant difference (p > 0.05) between speech perception outcomes at 3 or 9 months.
  
  
  CONCLUSIONS
  This study suggests that CI422 and Contour electrode both improve speech perception outcomes postoperatively, and there does not appear to be any significant difference in outcome between the two types of devices.
