“…[16] reported a prevalence of 76.7% on CBCT, which was higher than the present study. e prevalence of PAT reported in other studies ranged from 8%, [14] 14.7%, [18] 16.4%, [17] and 21.3% [7] to 65.8% [10] on CBCT. is wide range of prevalence in the literature can be attributed to the variety and size of the populations studied.…”

“…A PAT may be a limitation for surgeries involving the articular tubercle and TMJ. [7,14,15,17,[25][26][27] During surgeries such as eminectomy, eminoplasty, or miniplate insertion, a PAT may be found in the surgical area and the existence of a PAT increases the risk of perforation and untoward complications. [4,7,14,27] PATs are well-defined, asymptomatic, non-expansile, and non-destructive.…”

“…Clinicians should make the differential diagnosis of PAT with these diseases. [1,4,5,22,28] e previous studies about articular eminence pneumatization on panoramic radiographs, CT images, and CBCT images [1,[3][4][5][6][7][8][9][10][12][13][14][15][16][17][18] have reported the prevalence of PAT to be 1-6.2% on panoramic radiographs and 8-76.7% on CBCT images. [9,16,17,28] In studies that used panoramic radiographs as the imaging method, the prevalence was low because of the complexity and superimpositions of the adjacent structures on the examined area.…”

“…[4,16] e articular eminence pneumatization and the roof of the glenoid fossa were assessed bilaterally on axial, coronal, and sagittal sections in all CBCT images. Pneumatization type was classified as unilocular (well-defined, single, and oval radiolucent defect borders) and multilocular (numerous radiolucent small areas) [7,17,18] [Figure 1], and the degree of pneumatization was divided into four groups according to Al-Faleh and Ekram as follows: [19] Grade 0: Pneumatization limited to the mastoid process; Grade 1: Pneumatization between the mastoid process and the glenoid fossa; Grade 0 was evaluated as no PAT in our study.…”

Objectives: This study objectives to evaluate the type and degree of articular eminence pneumatization in individuals with different sagittal skeletal patterns. Material and Methods: Cone-beam computed tomography images of 139 patients were included in the study. The population was divided into groups according to their sagittal skeletal anomalies by A point-nasion-B point angle measurement. The laterality, grade, and type of pneumatization were recorded. Pearson Chi-square test and Fisher’s exact test were performed to evaluate gender, sagittal skeletal anomalies, pneumatization type, and grade. Results: A pneumatized articular eminence (PAT) was found in 74.8% of the population. Grade 1 pneumatization and the multilocular type where the most common pneumatization. There were no correlations between sagittal skeletal anomalies and pneumatization grades. Conclusion: The prevalence of PAT was high concerning the previous studies. However, there were no correlations between the sagittal skeletal anomalies, pneumatization type, and grade. Clinicians must always be aware of the potential for pneumatizations as they may cause untoward complications.

To determine the prevalence and characteristics of the zygomatic bone pneumatization (ZBP) and the presence and diameter of zygomaticofacial (ZFF), zygomaticoorbital (ZOF) and zygomaticotemporal (ZTF) foramina, correlating the findings with sex, age and facial skeletal pattern using cone beam CT (CBCT). 563 CBCT scans (1,126 ZB) were assessed and the type (uni/multilocular) and laterality of ZBP were determined, in addition to the presence and diameter of ZFF, ZOF and ZTF. Data was correlated with sex, age and facial pattern. 64 patients (11.37%) presented ZBP, with no differences among sex, age, facial patterns and types (p>0.05). Most pneumatizations were bilateral (68%; p<0.01). ZFF, ZOF and ZTF were detected in 926 (82.2%), 988 (87.7%) and 818 (72.6%) ZB, respectively. Differences were found for ZFF between age groups (p <0.005; >21-60 years). No differences were found for diameters (p >0.05). There is no relationship between sex, age and facial skeletal pattern with the presence of ZBP. The presence of ZFF was related to the age group. The knowledge about ZB anatomy and its variations is helpful for image interpretation as part of clinical and surgical treatment planning for this region.
