Abstract

Aim: The aim of the present
study is to determine the prevalence of the Pneumatized Articular Tubercle
(PAT) and to evaluate the characteristics of PAT in Cone-Beam Computed
Tomography (CBCT) images.

Material and Methods: A retrospective
study was performed using tomographic images of 276 patients (133 male, 143
female) aged between 12-85, who had attended to Oral and Maxillofacial
Radiology Department for different CBCT indications. Age, gender and presence
of PAT were recorded for all patients and, for cases of PAT, laterality and
radiographic types were also recorded. Obtained variables were entered SPSS 20
software and the prevalence of PAT was evaluated with chi-square test according
to genders and age groups.

Results: The mean age of the subjects
was 37.75 ± 17.1. Of the 276 patients, 39 (14.1 %) had PAT, of whom 22 were
female (15.4 %) and 17 were male (12.8 %). This difference was not
statistically significant (p=0.535). PAT was most common (25.6 %) in patients
aged between 20-29 years and least common (6.4 %) in patients aged between 50-59
years. The difference was statistically significant between age groups
(p=0.008). Of the 39 cases, 22 (56.4 %) had unilateral, and 17 (43.6 %) had
bilateral PAT. 35 (62.5%) PATs were multilocular and 24 (37.5%) were
unilocular.

Conclusion: PAT was
found to be a common anomaly on CBCT images. Presence and characteristics of
PAT should be evaluated with CBCT to avoid possible complications especially in
patients who will get a surgical intervention to the articular eminence region.
