title: Stereotactic approach to the trigeminal ganglion using a stereotactic frame and intraoperative computed tomography scans: technical note.
abstract: OBJECTIVE
  In this paper, a technique to place a probe at the trigeminal ganglion using a stereotactic frame and intraoperative computed tomography (CT) scans is described.
  
  
  METHODS
  The procedure is performed on the CT table using a stereotactic frame. After the coordinates have been obtained and then adjusted, the target is probed using the frame. In this study, intraoperative scans were obtained to confirm the accuracy of probe placement. After successful stimulation studies, radiofrequency lesions were made. Thirty-two procedures were performed on 26 patients.
  
  
  RESULTS
  Twenty patients were free of pain at a follow-up which lasted a median of 30 months. There was no permanent complication from the procedure.
  
  
  CONCLUSIONS
  The technique is straightforward, accurate and safe. It also enables the surgeon to obtain intraoperative confirmation of accurate probe placement on CT images.
