Abstract:
Endoscopic sinus surgery as a surgical technique for chronic sinusitis has become very popular. So, surgeons should be familiar with the structures and variation of the paranasal sinus to avoid the risks of endoscopic sinus surgery. Many investigations were performed to measure the sinus structure with CT and cadaver dissection. But, there were not to be performed precise measurements in paranasal sinus during operation. The authors measured the distance between anterior nares to intranasal structures such as uncinate process, bulla ethmoidalis, basal lamella, maxillary ostium, posterior wall of ethmoid sinus, anterior wall of sphenoid sinus and posterior wall of sphenoid sinus in 86 patients during endoscopic sinus surgery which were performed by one surgeon. The authors analyzed between measured distance in paranasal sinus and circumference and anteroposterior diameter of head using t-test. The results were as followed. 1) The distance from anterior nares to uncinate process was 45.3+/-2.8mm, to basal lamella 57.9+/-4.6mm, to maxillary ostium 48.3+/-4.7mm, to anterior wall of sphenoid sinus 69.9+/-3.6mm, and to posterior wall of sphenoid sinus 83.7+/-4.3mm. 2) There were no significant difference between sex, circumference and anteroposterior diameter of head.
