ABSTRACT
Background: Detection of air cavities, so called pneumatizations, nearby to the temporomandibular joint (TMJ) area is important, as they represent sites of minimal resistance and facilitate the spread of various pathologies into the joint as inflammation, tumor or fractures and serve as a possible complicating factor in TMJ surgery. Aims: To determine the prevalence of pneumatization of the articular eminence (PAT) and roof of the glenoid fossa (PRGF) using cone-beam computed tomography (CBCT). Study Design: Cross-sectional study. Methods: Acquired images of 111 patients (222 TMJs) were evaluated. The presence of pneumatization was recorded at the articular eminence and roof of the glenoid fossa. Age and gender were recorded for all patients and type (unilocular or multilocular) and laterality were noted for the cases of pneumatization. Results: The mean age of the study group was 48.86±18.31 years. Among all the patients, 73 (65.8%) had PAT, while 13 (11.7%) had PRGF. Forty-two (37.8%) of the patients had PAT bilaterally; whereas 3 of them (2.7%) presented PRGF bilaterally. The percentage of PAT was higher for females (73.6%) than males (51.3%) (p<0.05). Conclusion: CBCT images are an accurate and reliable means of detection of the exact size and type of pneumatization and the relationship of pneumatization to the adjacent tissues. This is especially significant before a surgical intervention is planned in this region, in order to make a sound diagnosis.
