“…Diagnosis of pneumatization of the articular eminence and TMJ fossa is important because it is a defect that facilitates the spread of various disease processes along the joint, including tumors, inflammation, and fractures due to minimal resistance (11). Also, in cases where it is necessary to surgically manipulate the articular eminence, PAT should be considered a complicating factor (4,12). Determination of these structures prior to surgical intervention may be helpful in the prevention of possible complications.…”

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.

“…The incidence of PAT was previously assessed on panoramic radiographs, and the prevalence was reported to be between 1% and 3.42% (4,6,8,9,13,14). In the literature, a few studies have assessed the prevalence of PAT on CBCT images (2,15).…”

“…Pneumatic bone cavities of the articular eminence are anatomical variations, and panoramic radiography appears to be an efficacious method to display their presence [27]. Degenerative joint diseases also affect articular eminence, and concavity replaces the normally convex eminence in severe cases [28].…”

The effects of compression on the image quality of digital panoramic radiographs

Size reduction through compression is an important issue that needs to be investigated for possible effects on image quality. The aim of the present study was to evaluate the subjective image quality of digital panoramic radiographs which were lossless and lossy compressed for the visualization of various anatomical structures. Fifty-five digital panoramic radiographs in Tagged Image File Format (Tiff) were used in the study. Two types of lossy (Joint Photographic Experts Group (Jpeg)) and one type of lossless (Lempel-Ziv-Welch) compression were applied to the original radiographs. These radiographs were evaluated by two observers separately for the visibility of some anatomical structures with visual grading. Mean quality number for each radiograph was obtained. The differences between the mean quality numbers in each compression and original image mode were evaluated with Friedman test. Pair-wise comparisons revealed that there were statistically significant differences between all groups (p = 0.000) for all comparisons except for Jpeg_1 and Jpeg_2 groups. Kappa statistics was used to evaluate inter- and intra-observer agreements. Intra-observer agreements were ranging from 0.229 to 1.000 and inter-observer agreements were ranging from 0.154 to 1.000. The observers had better inter- and intra-observer agreements in highly compressed Jpeg_1 images. The anatomical structures evaluated in this study had better visibility in Tiff images than Jpeg images except for mandibular canal and mental foramen. While Jpeg compressed images offer high inter- and intra-observer agreements, the visibility of anatomical structures are better in Tiff images except for mandibular canal and mental foramen.

“…The term PAT was used for the first time by Tyndall and Matteson to define air cells that arise in the roof of the zygomatic arch and in the articular eminence of the temporal bone, that is, similar to air cells in the mastoid process and ethmoid bone (5). Tyndall and Matteson also reported about the anatomical relationship of PAT with mastoid air cells.…”

Introduction: The aim of this retrospective study was to identify the prevalence and properties of pneumatized articular eminence (PAT) in a group of Turkish population using CBCT.Material and Methods: The subjects for this retrospective study consisted of all 300 adult patients who referred to the Department of Oral Diagnosis and Radiology, Marmara University Faculty of Dentistry, and underwent a single CBCT examination from 2016 to 2017. Age and gender were noted for all patients, and for the cases of pnuematization, sides and type were recorded.Results: Of the 300 patients, 98 (32,0%) had PAT, of whom 43 were female and 55 were male. PAT was seen 14% on bilateral sides, 10% on the right side and 8.7% on the left side. 51% of those which had pneumatization were unilocular and 49% were multilocular Conclusion: CBCT images are a true and confident tool for the exploration of the definite size and pattern of pneumatization and the relationship of pnuematization to the adjacent tissue. ın case of surgical treatment is planned or for the differential diagnosis of suspected cases, panoramic radiographs should be supported with CBCT.
