Objective:
To observe the CT imaging features of anatomic structure related to endoscopic axilla approach for surgery of the frontal recess and frontal sinus.
Method:
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.
Result:
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.
Conclusion:
Sixteen line high speed spiral computed tomography is helpful to endoscopic axilla approach for surgery of the frontal recess and frontal sinus.
