Prevalence of Pneumatized Articular Eminence of the Temporal Bone and Its Importance in Maxillofacial Surgery

Abstract

Objective: Pneumatization is the presence of air filled cavities in a bone. They are seen in the root of the zygomatic arch of the temporal bone and in the articular eminence. The aim of this research was to determine the prevalence and type of pneumatized articular eminence of the temporal bone (PAT) among the patients of the dental clinic and to explain its importance in maxillofacial surgery. MaterialsandMethods:Analysis of 8400 panoramic radiographs was performed. Age and sex of all the patients were recorded. Results: PAT was discovered in 334 patients, accounting for prevalence of 3.9%. For these 334 patients, 138 (41.3%) were male and 196 (58.7%) were female. Two hundred ninety (65.6%) occurred unilaterally and 115 (34.4%) bilaterally. Two hundred fifty one (55.9%) of PAT presented with multilocular type, 182 (40.5%) with unilocular type, and 16 (3.5%) with trabecular appearance. In 194 (58%) cases, PAT was located between the deepest point of the glenoid fossa to the crest of the articular eminence (grade 2), and in 140 (42%) cases, PAT extended beyond the crest of the articular eminence (grade 3). PATs were found more common in females in the third decade of life. Conclusion: Due to the fragile nature of these defect, surgeons who are planning to carry out temporomandibular joint surgery should be extra cautious when dealing with pneumatized articular eminence especially in third decade female people in population. Amaç: Pnömatizasyon, bir kemikte hava dolu kavitelerin varlığıdır. Temporal kemikte, zigomatik ark kökü ve artiküler eminenste görülebilirler. Bu çalışmanın amacı diş kliniği hastaları içinde temporal kemikte pnömatize artiküler eminens (PAT) prevalansını ve tiplerini saptamak ve maksillofasiyal cerrahideki önemini vurgulamaktır. Gereç ve Yöntemler: Sekiz bin dört yüz panoramik radyografinin analizi yapıldı. Tüm hastaların yaş ve cinsiyetleri kaydedildi. Bulgular: Üç yüz otuz dört hastada PAT görüldü ve prevalansı %3,9 olarak hesaplandı. Bu 334 hastanın 138'i (%41,3) erkek, 196'sı (%58,7) kadındı. İki yüz dokuz PAT (%62,5) tek taraflı, 115 (%37,5) bilateraldi. Multiloküler tip 251 (%57,1), uniloküler tip 172 (%39,1) ve trabeküler tip olarak 16 (%3,6) PAT mevcuttu. Yüz doksan dört (%58,0) PAT olgusu glenoid fossanın en derin noktası ile artiküler eminens arasında

Articular eminence pneumatization in patients with different sagittal skeletal patterns: Cone-beam computed tomography study

“…CBCT images do not affect from superimpositions, thus the higher prevalence of multilocular PAT might be related to the use of CBCT images. [7,10,14,21] At the present study, the prevalence of multilocular PAT was higher than unilocular PAT in studies by Akyol and Orug, [28] Khojastepour et al, [16] Chicarelli et al, [17] Orhan et al, [13] Ladeira et al, [7] Sallı et al, [18] and Ilgüy et al [10] In the present study, multilocular pneumatization (94.5%) was more frequent than the unilocular type (5.5%), similarly to other studies.…”

“…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.…”

“…This outcome is in concordance with findings from prior research conducted by Gupta et al [ 32 ]. However, Akyol et al, have reported gender differences in ZACD prevalence, suggesting that gender may not consistently predict ZACD occurrence across all populations [ 33 ]. Carter et al [ 3 ].…”
