Oral and maxillofacial radiologyPrevalence of pathologic findings in the maxillary sinus in cone-beam computerized tomography
Section snippets
Material and Methods
This retrospective study included 1,029 consecutive patients of whom individual factors of gender, age, and indication for scanning had been recorded. The study was approved by the Ethics Committee of the Medical Faculty of the University of Cologne (approval no. 05-111).
The mean age of the patients was 44.19 ± 20.3 years, the youngest patient was 8 years old, and the oldest patient was 107 years old at the time of the investigation (Fig. 1). For statistical analysis, patients were separated
Results
Pathologic findings in either 1 or both of their sinuses were found in 579 patients (56.3%). Two hundred eighty patients (27.2%) showed pathologic signs in both and 299 patients (29.1%) in either one of their sinus. Four hundred fifty (43.7%) of the 1,029 investigated patient scans showed no pathologic signs within either left or right maxillary sinus. Results separated for the left and right sinus are listed in Table II, Table III.
Either one or both sinuses of 73 patients (7.1%) showed total
Discussion
In this study 1,029 CBCT datasets were retrospectively evaluated for pathologies in the maxillary sinus. The results of this study are in concordance with studies that have previously addressed the topic using different imaging technologies. The prevalence of inflammation in the maxillary sinus based on CT images was reported in the literature to be between 63% and 83.2%.12, 13 Studies based on magnetic resonance imaging (MRI) found a prevalence of 50%, even for children.14 Studies based on
Conclusions
The detection of pathologies in the maxillary sinus seems to be feasible using CBCT imaging. Further studies are required to prospectively compare CT and CBCT in detecting pathologic lesions in the maxillary sinus and planning maxillary sinus surgery. Pathologic changes observed as incidental findings are frequent in CBCT and have to be followed-up accordingly.

2022, Journal of EndodonticsCitation Excerpt :There were statistically significant differences (P < .05) between the type of MS abnormalities and all the variables studied (Table 1). Ritter et al33 measured the prevalence of pathologic findings in the MS using CBCT scans and found a rate of 56.3%; 280 patients (27.2%) had pathologic signs in both and 29.1% in 1 or the other sinus. Both sinuses of 73 patients (7.1%) were totally opacified.
