Anatomical Presentation of Sinus Membrane and Ostium in Cone Beam Computed Tomographic Scan

Abstract

Abstract: Objective: To analyze the characteristics of sinus membrane and ostium by cone beam computed tomographic, and to assess the correlation between them. Methods: The study included 150 CBCT radiographs (300 maxillary sinuses). The sinus membrane thickness was assessed by three-dimensional reconstruction,and recorded the radiographic findings of sinuses. Additionally, ostium patency was classified as patent or obstructed. Results: The mean sinus membrane thickness was 9.53mm. Mucosal thickening was found in 65.67% of the maxillary sinuses, and was most frequently observed between 2 and 5mm. Ostium obstruction was observed in 10.67% sinuses. Both type and degree of membrane thickening demonstrated significant bivariate associations with ostium obstruction. Conclusion: CBCT scan is recommended to expand to include the maxillary sinus ostium. An ENT consultation is recommended for patients with ostium obstruction and sinus disease, especially for those whose mucosal appearance was classified as ploypoid thickening, partial opacification with liquid accumulation, and total opacification or membrane thickening was more than 10mm.
