Prevalence of maxillary sinusopathies using cone beam computed tomography
Keywords:Cone Beam Computed Tomography, Maxillary Sinus, Diagnostic Imaging
This study aimed to evaluate the prevalence of sinusitis in MS through computerized tomography of cone beam (CTCB) of the maxilla in patients selected for the planning of dental implant according to gender and age. All 226 CT images were analyzed and visualized independently by three specialized surgeon dentists (SD) to verify the presence of sinusitis. Those changes of normality were classified as: sinus opacification, mucosal thickening, antral pseudocyst, polyps, and pneumatization. We found the presence of sinus diseases in 156 (69%) out of the 226 CTCB analyzed, under the form of sinus opacification in 69 (30.5%), mucosal thickening in 63 (27.9%), pneumatization in 57 (25.2%), antral pseudocyst in 29 (12.8%) and polyps in six (2.7%), which occurred in an isolated way or simultaneously. When we observe the simultaneous association of two or more sinus, we found them in 56 (24.8%) out of all the CTCB observed in the sample. The mucosal thickening and pneumatization were the most frequent association, occurring in 8.4% of the sample. Regarding the gender, no difference was observed between the male and female genders concerning the rate of prevalence of the sinusitis in SM. In relation to age groups, difference was found only for polyp, and individuals aged over 61 years old showed higher prevalence rate. Our study shows the importance of CTCB for implant in posterior maxilla due to the higher prevalence of sinusitis found in asymptomatic patients.
