Description
Summary:Abstract Purpose The purpose of this study was to retrospectively investigate the aetiology, pattern, and treatment of mandibular condylar fractures in our department over the past 22 years. Patients and methods Data of patients who sustained mandibular condylar fractures from 1988 to 2009 were recorded, including fracture aetiology, pattern of condylar fracture, time, age, sex, associated injury, patient transferred by other clinics, lag time and treatment method. Data analysis included X2 test, Fisher exact test, t -test, Ridit analysis and Logistic regression analysis. Results The sample was composed of 549 patients (749 condylar fractures), 404 male and 145 female (male:female = 2.79:1), with a mean age of 30.12 ± 14.44 years. Road traffic accidents were the most common cause (248, 45.2%). Condylar head fractures were significantly related to a fall at ground level ( p  = .001). A fall from a height had a 3.19-fold risk of bilateral condylar fractures (odds ratio, 3.19; 95% confidence interval, 1.33 to 7.65; p  = .010). A majority of the condylar fractures (693, 92.5%) were treated by a surgical procedure. Condylar head were mostly removed (95.0%, p
