“…In terms of the type of pneumatization, most researchers found an almost equal distribution of unilocular and multilocular types (5, 8, 9, 10, 14, 15), except Orhan et al (15) and Laderia et al (2), who reported a higher incidence of the multilocular type (75% and 98.7%, respectively). The present study determined a higher prevalence of the multilocular type for PAT (86.1%, Table 1).…”

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 accessory air cells are believed to begin to pneumatize after puberty and achieve full size several years later as mastoid air cells [7,25]. Moreover, the puberty period has been designated to commence at 12-13 years of age [6,7,24]. In contrast to this statement, Hoffman et al [10], Orhan et al [7], and Yavuz et al [5] detected cases of PAE at 7, 11, and 10 years of age.…”

“…Moreover, less superficially located regions (such as the medial portion of the articular eminence) may only be visible by CT. Among these reports, few studies [6,24] were conducted in the childonly population, and only a single study [24] investigated the correlation between orthodontic malocclusion and PAE. Therefore, data on pneumatization in this region are limited.…”

“…Therefore, data on pneumatization in this region are limited. Additionally, subjects with malocclusions have been suggested to display a significantly higher prevalence of signs and symptoms of temporomandibular joint (TMJ) dysfunction than others, and may undergo TMJ surgery [24]. The presence of PAE in these patients may be a contraindication for surgical intervention.…”

Pneumatized articular eminence in a cohort of orthodontic patients with different sagittal skeletal anomalies: a retrospective cone beam computed tomography study

Objectives The aim of this study was to determine the prevalence and characteristics of pneumatized articular eminence (PAE) in dental patients using cone beam computed tomography (CBCT) with respect to age, sex, and type of skeletal anomaly. The results were then compared to prevalence studies regarding PAE in the literature. Study design A retrospective study of 603 orthodontic patients aged between 6 and 24 years was performed using sagittal and coronal CBCT images at the Department of Oral and Maxillofacial Radiology (Erzurum, Turkey). The age, gender, skeletal anomaly, and lateral were recorded for all patients, and the types were noted for cases of PAE. The chi-squared test was used for statistical analyses. Results Sixty-four PAEs were found in 39 orthodontic patients, representing a prevalence of 6.47%. No significant differences in sex (p = 0.153), age (before and after puberty, p = 0.389), and type of skeletal anomaly were observed (p = 0.271). Conclusions A higher frequency of PAE was detected among dental patients aged 6-24 years when compared to previous studies, most likely because of the use of CBCT images. No significant relation was observed between PAE and the type of skeletal anomalies. One, however, must be aware of these structures to avoid complications in cases for which surgical treatment is planned due to the occlusion and recognize its role in the onset or perpetuation of temporomandibular joint dysfunction.
