Sagittal fracture of the maxilla.

Although sagittal fractures of the maxilla are not common, they can be observed in some cases following severe trauma to the facial skeleton. 18 of the 23 cases reported had combined mandibular and midfacial fractures. Sometimes in severe cases they may demonstrate instability with conventional methods of treatment; thus for adequate stabilization they may need a palatal splint, direct wiring (internal fixation in the buttresses), intermaxillary fixation and cranial suspension.
