Abstract

Purpose: The temporal bone depicts a variety of pneumatization patterns which are incidental findings but have a great clinical significance for planning surgical procedures in this area. The purpose of the present study was to evaluate the prevalence and incidence of pneumatization of articular tubercle and roof of glenoid fossa. Methods: 520 CBCT scans of 260 patients were evaluated to determine pneumatized articular eminence prevalence and characteristics. Gender, laterality and type of pneumatization were observed for both the left and right sides. Chi-square test was used to evaluate the relationship between pneumatized articular eminence and roof of glenoid fossa and gender and type. The software used for the statistical analysis was SPSS version 21.0 and the p-value < 0.05 were considered to indicate statistical significance. Results: PAT was detected in 180 (34.6%), consisting of 105 (20.2%) unilocular and 75 (14.4%) multilocular. PRGF was observed in 224 (43.1%) patients, consisting of 80 (15.4%) unilocular and 144 (27.7%) multilocular. There was 102(19.6%), 93(17.9%) unilateral PAT and PRGF and 44 (8.5%), 74 (14.2%) bilateral PAT and PRGF respectively. Significant corelation was observed for the distribution of types of PAT according to gender (p-value= 0.001).
