ABSTRACT

Chronic paranasal sinusitis has been a trouble-maker in the field of otolaryngology. But nowadays, functional endoscopic sinus surgery is popularized with the help of ostiomeatal CT scan for the purpose of reestablishing ventilation, and mucocilliary clearance of the sinuses. With its increasing use, the importance of OMU CT scan is well-known and it is now playing an important role not only in screening but also in predicting any anatomical variation with its outstanding resolution power.

400 sides of OMU CT scans taken in 200 patients with symptoms of chronic paranasal sinusitis were analyzed according to the bony anatomical variants and mucosal involvement to get their prevalences. The purposes of this study are to determine the background prevalence of bony anatomical variants and mucosal abnormalities of the paranasal sinuses and to assess the possible pathogenicity of their findings in patients with sinusitis.

The results were as follows:

  1. We could observe septal deviation in 38.3% of cases, concha bullosa in 14.5% of cases, paradoxical curvature of the middle turbinate in 32.3% of cases, Haller’s cell in 30.3% of cases, lateralized uncinate process in 9.8% of cases, hypertrophic uncinate process in 30.0% of cases, defect in the lamina papyracea in 6.8% of cases, type I cribriform plate in 49.0% of cases, prominent optic nerve and internal carotid artery within the sphenoid sinus in 8.0% and 28.0% of cases, respectively.

  2. The prevalences of mucosal involvement were in the order of anterior ethmoid, maxillary sinus, posterior ethmoid sinus, frontal sinus and sphenoid sinus.

  3. The relationship between nasal septal deviation and sinus disease and that between disease of anterior ethmoid or ethmoidal infundibulum and sinus disease were statistically significant.

  4. The relationship between concha bullosa or paradoxically curved middle turbinate and sinus disease was not significant.

  5. The average distance from the anterior nasal spine to the anterior wall of the sphenoid sinus was 60 mm in males and 57 mm in females.
