title: Cochlear implantation assisted by noninvasive image guidance.
abstract: OBJECTIVE
  We recently developed a new noninvasive registration method for image-guided otologic surgery (STAMP method). We investigated the benefit and potential drawback of our new method in clinical application and tested the feasibility of routine image-guided surgery.
  
  
  METHODS
  Retrospective case review.
  
  
  METHODS
  Tertiary referral university hospital.
  
  
  METHODS
  Forty-six cases (45 patients) that underwent cochlear implantation in Kyushu University Hospital during the period of 2007 and 2010 were informed of the option to use navigated surgery.
  
  
  METHODS
  Twenty-five cochlear implantations were performed using STAMP-registered image-guided surgery.
  
  
  METHODS
  The error of image-guided surgery and time of surgery were collected and analyzed.
  
  
  RESULTS
  STAMP method offered serviceable accuracy in 18/25 cochlear implantations. The learning curve suggested that the accuracy is at least stabilizing, if not improving, and the success rate is expected to rise. Time of cochlear implant surgery was not significantly extended by the use of image guidance.
  
  
  CONCLUSIONS
  STAMP method had comparable errors with minimal invasiveness. Our new method potentially enables routine use of image-guided surgery.
