CT-Based Profile of Mandibular Fractures and Application of the AO CMF Classification: A Study of Cases from Two Hospitals in Yaoundé, Cameroon

Mandibular fractures are common in maxillofacial trauma and require precise diagnosis for optimal management. This study evaluates the applicability of the AO CMF classification system in an African setting, aiming to create a structured CT-based profile of mandibular fractures. A retrospective cross-sectional study was conducted over six months at the Central and University Teaching Hospitals of Yaoundé. CT scans of 201 patients were analyzed, and 82 cases of mandibular fractures were identified and classified. Young adult males were predominantly affected, with motorcycle-related accidents being the main cause. Fractures mostly involved the basal bone, particularly in the symphyseal and body regions. The majority were simple fractures, though displaced and fragmented patterns were also observed. The AO CMF classification allowed for detailed mapping of fracture sites, types, and associated dental injuries. This study highlights the importance of standardized diagnostic tools like the AO CMF classification in improving the assessment and management of mandibular trauma in resource-limited settings.
