简要总结
This retrospective observational study aimed to investigate the aetiology and fracture patterns among patients with mandibular condylar fractures (MCF) who were treated at a trauma center in Shiraz, Iran, between 2018 and 2020. A total of 122 patients were included. The study involved collecting data on fracture characteristics, including anatomical location, classification (MacLennan and Loukota systems), angle of fracture lines, and the presence of concomitant maxillofacial injuries. The objective was to examine correlations between these characteristics and demographic or clinical factors such as age, sex, and mechanism of injury.
详细描述
This is a retrospective cohort study conducted at a major trauma center affiliated with Shiraz University of Medical Sciences, Iran. The study enrolled patients diagnosed with unilateral or bilateral mandibular condylar fractures between January 2018 and December 2020. Data were extracted from clinical records and radiographic evaluations. Fractures were classified according to the MacLennan and Loukota systems, and relevant demographic and injury-related information was recorded. No interventions were administered as part of this registry. All procedures were conducted under approval from the institutional ethics committee. The primary aim was to investigate patterns in fracture characteristics and their associations with trauma mechanisms and patient demographics.
