title: [Update: catheter-based balloon dilatation of the sinuses without fluoroscopy. Dilation technique with an illumination system].
abstract: BACKGROUND
  Catheter-based balloon dilation of the sinus ostia follows the general guidelines for functional endoscopic sinus surgery with the goal of reopening the sinus ostium to restore ventilation and drainage of the sinus and reestablish normal mucosal function, while maintaining normal mucosal tissue and avoiding scar tissue formation. A main criticism of this procedure questions the necessity of fluoroscopy with the C-arm since its use exposes patients and medical personnel to radiation and the C-arm is not available in every ENT operating room.
  
  
  METHODS
  Catheter-based balloon dilation of the sinus ostia was performed with the Relieva Luma Sinus Illumination System (Acclarent, Inc.) without fluoroscopy.
  
  
  RESULTS
  Using this method of illumination, it was possible to localize the device tip transcutaneously in the maxillary and frontal sinus cavities, making radiological exposure unnecessary.
  
  
  CONCLUSIONS
  The advantages of catheter-based balloon dilation without fluoroscopy lie in the elimination of radiation exposure to the patient and personnel as well as the cost savings. Randomized controlled trials should be planned to further evaluate this technique.
