Then try it with a bag of bagels. To wit, the stiffer a ring bone is, the more likely it is to break in more than one place. The more flexible it is, the more likely it is to break in just one place. Like the nose, the mandible also has a prominent position on the face, making it a favorite target for either of these mechanisms. Mandibular fractures have traditionally occurred at twice the prevalence of facial fractures, but this ratio has been decreasing with the increasing prevalence of high-speed auto accidents.
Mandibular fractures can occur at any of the following sites.
When double fractures occur, they are usually on contralateral sides of the symphysis. Common combinations include the angle plus the contralateral body or condyle. Triple fractures occasionally occur, and the most common type is fracture of both condyles plus the symphysis. The mandible may also be dislocated without fracture, sometimes spontaneously during a large yawn. The patient usually presents with considerable pain.
