The purpose of this study was to investigate the prevalence of glenoid fossa and condylar fractures in patients with mandibular fractures using multidetector computed tomography (MDCT). %26lt;br%26gt;A prospective study was performed in 227 patients with mandibular fractures who underwent 64-MDCT. Mandibular fractures were classified into four types: median, paramedian, angle and condylar. Statistical analysis of the relationship between prevalence of condylar fractures and mandibular fracture locations was performed using chi(2) test with Fisher%26apos;s exact test. A P value less than 0.05 was considered statistically significant. %26lt;br%26gt;The prevalence of condylar fracture was 64.8 % of all patients with mandibular fractures, 66.7 % of median type (P = 0.667), 45.5 % of paramedian type (P = 0.001) and 12.3 % of angle type (P = 0.000), respectively. Furthermore, glenoid fossa fracture was seen in 1.4 % of patients with condylar fractures. %26lt;br%26gt;The results of the presented study suggest focusing also on incidental findings such as glenoid fossa fractures. %26lt;br%26gt;aEuro cent The prevalence of condylar fracture was 64.8 % in patients with mandibular fractures. %26lt;br%26gt;aEuro cent Glenoid fossa fracture was seen in 1.4 % of patients with condylar fractures. %26lt;br%26gt;aEuro cent The study suggests a focus on incidental findings such as glenoid fossa fractures.
