title: Is image guidance accurate in children sinus surgery?
abstract: OBJECTIVE
  To compare the precision of the calibration of a 3D navigation system for endoscopic sinus surgery in children and adults. To compare the complication and calibration failure rates of the system in both populations.
  
  
  METHODS
  The precision of the calibration of the Stryker navigation system (Stryker Neuronavigation ENT 2.0 Software) was found in the charts of children and adults operated on for various nasosinusal procedures between May 2008 and February 2013 in a tertiary care center. Demographic characteristics and complication rates were also noted.
  
  
  RESULTS
  Thirty-eight adults and 21 children were included in the study. No statistically significant difference was found between the two groups with an identical mean precision of 0.7mm (p=0.90). The rate of precision unreliability and calibration failures was not statistically different between the two groups (14% children vs 5% adults). No major complications occurred in both groups (p=1.00). No demographic characteristic predicted a failed calibration (height, weight, BMI, age).
  
  
  CONCLUSIONS
  The Stryker image-guided system can provide a precision level that is equivalent in both children and adults. This study also demonstrated an absent/low complication rate respectively for children and adults post endoscopic surgery.
