Abstract

Background: The articular tubercle is a site prone to pneumatization within the
cranial bones. Knowledge of the anatomical variations of pneumatization adjacent
to the temporomandibular joint (TMJ) is an important issue. Air cells exhibit decreased
resistance to trauma, facilitate the spread of various pathologies in the TMJ,
such as inflammation, tumours or fractures. Articular tubercle pneumatization may
cause complications during TMJ surgery. Information of possible location allows
to detect and conduct differential diagnosis of pneumatization of the articular
tubercle (PAT) during cone-beam computed tomography (CBCT) examinations. The
aim of this study is to determine the prevalence and characteristics of PAT, with
respect to age, gender, location and type through assessment in CBCT images.
Materials and methods: Articles were selected through database search (PubMed,
Scopus, Google Scholar), in which the main objective was to assess the prevalence
of articular tubercle pneumatization using CBCT. Search strategies included the
following keywords: “pneumatized articular eminence” and “CBCT”, “pneumatized
articular tubercle” and “CBCT” and “zygomatic air cell defect” and “CBCT”.
A meta-analysis of prevalence using a random effects model was performed.
Results: Fifteen studies met the selection criteria. The results showed that an
overall prevalence of articular tubercle pneumatization was 25.22% (n = 6393;
95% confidence interval [CI] 15.84–35.94). The occurrence of PAT in females was
25.14% (n = 3064; 95% CI 14.96–36.94). The frequency of PAT in males was
25.81% (n = 2671; 95% CI 15.30–37.99).
Conclusions: There was no correlation between the frequency, location or type
of PAT with age and gender.
