title: Multiplanar sinus CT: a systematic approach to imaging before functional endoscopic sinus surgery.
abstract: OBJECTIVE
  The purpose of this essay is to present a systematic approach to the use of coronal, axial, and sagittal images for CT evaluation of the sinuses before functional endoscopic sinus surgery (FESS).
  
  
  CONCLUSIONS
  We present a systematic approach to the use of coronal, axial, and sagittal images in CT evaluation before FESS. Each imaging plane is valuable for displaying anatomic variants, which can predispose a patient to recurrent disease and affect the surgical approach, and critical variants, which can make surgery hazardous.
