a. Fractures of the Maxilla. Fractures of the maxilla commonly occur as
horizontal fractures through the floor of the nose, horizontal fractures of the premaxillary
area, tuberosity fractures, alveolar process fractures, and nasal process fractures. The
nasal bone is the most common facial bone fracture. See figure 3-2.
