Purpose We developed a surgical navigation system that warns the surgeon with auditory and visual feedback to protect the facial nerve with real-time monitoring of the safe region during drilling. Methods Warning navigation modules were developed and integrated into a free open source software platform. To obtain high registration accuracy, we used a(More)
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. STUDY DESIGN Retrospective case review. SETTING Tertiary referral university(More)
This work proposes an image-guided robotic Mastoidectomy. A surgical navigation software was developed to guide the robot without damaging the critical area. A forbidden-region virtual fixture is implemented for safety. A human-robot collaboration control mode is used to allow the human intervention during surgery, to compensate tremor by operator, and to(More)
   Image-guided otological surgeries require minimal invasiveness and high accuracy, and these two factors usually compete with each other. Our recently developed registration method, called the STAMP method, showed minimal invasiveness with accuracy comparable to that of the current more invasive registration methods used in image-guided temporal bone(More)
Purpose The temporal bone that is drilled in otologic surgery conceals important organs inside small area, e.g. carotid artery, jugular vein, facial nerve, inner ear etc. Surgeons will reach some of these organs as surgical targets while not injuring others. Three dimensionally located complex anatomical structures in the bone imply a necessity for(More)
