title: Implanting common cavity malformations using intraoperative fluoroscopy.
abstract: OBJECTIVE
  To describe a safe and effective technique for the implantation of common cavity cochleae.
  
  
  METHODS
  Retrospective case review.
  
  
  METHODS
  Tertiary referral center.
  
  
  METHODS
  Fifteen cochleae in 9 adults and children with common cavity deformities implanted with and without the use of intraoperative fluoroscopy.
  
  
  METHODS
  : Fluoroscopically assisted cochlear implantation.
  
  
  METHODS
  Rates of extracochlear placement, bending, kinking, intrameatal placement, and complications were analyzed. Numbers of electrodes inserted, number of active electrodes, and speech performance were compared between the 2 groups.
  
  
  RESULTS
  Half of the nonfluoroscopy group had suboptimal placement of their electrode arrays. This group also had a higher rate of complications, lower numbers of electrodes implanted, and lower number of active electrodes at follow-up. Results of speech perception testing suggest that fluoroscopically assisted implantation of the common cavity results in improved performance.
  
  
  CONCLUSIONS
  Intraoperative fluoroscopy is an easy, safe, and effective technique that results in improved outcomes for cochlear implant patients with common cavity deformities.
