Abstract:
Background: Fracture of the vertical mandibular units caused by trauma are very common, difficulty in clinical diagnostics, if the emergency management is incorrect it will be dangerous to life of patients. Objective of this study: describe the clinical and radiological characteristics of fracture of the vertical mandibular units. Materials and method: Cross-sectional descriptive methods on 71 patients with the fracture of the vertical mandibular units caused by trauma, examined and treated at the Hue University Hospital and Hue Central Hospital from 05/2012 to 04/2013. Results: the majority of the patients were males (83.1%), 19 - 39 years of age (63.4%), the most common cause was road traffic accident (77.5%). The majority of them had associated fractures (74.6%), associated horizontal mandibular fracture (63.4%), occuring often in parasymphyseal region (49.4%). The majority of the vertical mandibular fracture were caused by traumatic force on parasymphyseal region (49.4%) and direction of traumatic force on one side of mandible (63.3%). Condylar fracture (55.0%) was the most fracture of vertical mandibular units, followed by mandibular angle fracture (38%); mandibular angle fracture is often unfavorable (92.6%) and displaced (63.0%) fracture; the majority of the condylar fracture was condylar head (48.7%) and displaced fracture (61.5%). The most common symptoms were difficult chewing (97.2%), painful swelling (91.5%), limited mouth openning (88.7%), throbbing pain (85.9%) and malocclusion (77.5%). The rate of films used to diagnose including panorama (97.2%), facial film (54.9%), oblique lateral film (45.0%) and CT Scans (39.4%). The rate of fractured detection of CTScans is 100%, of panoramic and posterior-anterior radiographs in mandibular angle fracture was in succession 100% and 94.4%, in condylar fracture was 94.9% and 26.3%. Conclusion: vertical mandibular fracture occured often in condyle and angle, associated often with parasymphyseal fractures; clinical diangosis based on limited mouth openning, throbbing pain and malocclusion; radiographs used often and had high rate of fractured detection were panorama and CT Scans. Key words: vertical mandibular fracture, clinical and radiological characteristics
