title: [Computed tomography analysis of anatomic structure related to endoscopic axilla approach for surgery of frontal sinus].
abstract: OBJECTIVE
  To observe the CT imaging features of anatomic structure related to endoscopic axilla approach for surgery of the frontal recess and frontal sinus.
  
  
  METHODS
  Thirty patients without a history of frontal sinus disease were undergone 16 line high speed spiral computed tomography. The computed tomographic images were analyzed to measure the related structures.
  
  
  RESULTS
  The vertical distance from the front attachment point of the middle turbinate to the skull base was 13.88 +/- 2.59 mm. The horizontal distance from the top point of the axilla of the middle turbinate to the anterior wall of the frontal sinus outflow tract was 5.77 +/- 12.32 mm, to the anterior wall of the nasal cavity was 13.67 +/- 12.54 mm, to the lamina papyracea or lacrimal sac was 5.89 +/- 1.69 mm.
  
  
  CONCLUSIONS
  Sixteen line high speed spiral computed tomography is helpful to endoscopic axilla approach for surgery of the frontal recess and frontal sinus.
