Pneumatized articular tubercle (PAT) is more prevalent than previously thought. Cone-beam computed tomography (CBCT) revealed a 12.5% prevalence, significantly higher than panoramic radiography
Area of Science:
- Anatomy
- Radiology
- Oral and Maxillofacial Surgery
Background:
- Air cells in the zygomatic arch and articular eminence were first described in 1985.
- These air cells, known as pneumatized articular tubercle (PAT), do not extend beyond the zygomaticotemporal suture.
Purpose of the Study:
- To investigate the prevalence and patterns of pneumatized articular tubercle (PAT).
- To compare diagnostic capabilities of digital panoramic radiography and cone-beam computed tomography (CBCT) for PAT detection.
Main Methods:
- Retrospective analysis of 3000 panoramic radiographs and 200 CBCT scans.
- Evaluation of radiographic features indicative of pneumatized articular tubercle.
Main Results:
- Digital panoramic radiography showed a PAT prevalence of 1.96%.
- Cone-beam computed tomography (CBCT) identified a significantly higher PAT prevalence of 12.5%.
Conclusions:
- This study establishes the prevalence of pneumatized articular tubercle in the studied population.
- CBCT is a more sensitive imaging modality for detecting PAT compared to panoramic radiography.

Computed Tomography
The technique was invented in the 1970s and is based on the principle that as X-rays pass through the body, they are absorbed or reflected at different levels. In the technique, a patient lies on a motorized platform while a computerized axial tomography (CAT) scanner rotates...

Beams
Based on geometry, beams can be straight, tapered, or curved. Straight beams are the most common type and have a constant cross-section throughout their length. Tapered beams, on the other hand, have a varying cross-section along...
