Abstract
OBJECTIVE: The aim of this study was to determine the prevalence and characteristics of pneumatization of the articular tubercle (PAT) and pneumatization of the roof of the glenoid fossa (PRGF) in a large population using cone-beam computed tomography (CBCT). MATERIALS AND METHODS: This study was designed to evaluate the CBCT images of 1000 patients. The prevalences of the pneumatizations by age, sex, locularity, and laterality were determined. The significance of differences between variables was evaluated by the Chi-square test and analysis of variance. RESULTS: PAT was detected in 28.4% of the zygomatic bone sides and PRGF in 29.6%. Bilateral PAT was detected in 176 (17.6%) patients and bilateral PRGF in 195 (19.5%). The mean age of patients with PAT was 47.33 years and that of patients with PRGF was 45.62 years. Multilocular appearance was observed significantly more often than unilocular type for both pneumatizations (p < 0.01). Unilateral PAT cases were slightly, but significantly, higher than bilateral PAT cases (p = 0.047), while no significant difference was observed between unilateral and bilateral PRGF cases. CONCLUSIONS: In conclusion, PAT and PRGF can be assessed more accurately on CBCT images than on plain radiographs. During routine radiological investigations, maxillofacial radiologists should be aware of zygomatic air cells.
