The mandible is one of the most frequently fractured facial bones along with the nose and zygoma, and the most frequently fractured bone in the multiple-injured patient. Mandibular fractures account for approximately 20 percent of all facial fractures. Motor vehicle accidents and physical altercations are the most common causes of fractures of the mandible. Areas of weakness in the mandible are the neck, the subcondylar region, and the angle; these will be the most frequently seen areas to fracture. The presence or absence of teeth will also contribute to the location of the fracture. Greater than one half of all mandible fractures are multiple; therefore, one should always look for a second site of fracture. Mandibular fractures may be open or closed either through the skin or intraorally through mucosa (compound fractures). |
