Sagittal fractures of maxilla and palatal bones.

Isolated injuries of these bone structures is very rare, they are usually combined with other fractures of this facial part. A fracture line runs in most cases through the suture connecting palatinal processes of both maxilla s and horizontal lamellae of palatal bones. At the front part, it runs through foramen incisivum and between alveoli of the upper middle incisor teeth. Widening of the palatal suture causes the periosteum, that is firmly attached to bones, to break off thus creating an oro-nasal connection.

A sagittal fracture occurs most often upon a force acting from below to the lower jaw and by transfer of impact to the upper teeth that causes the aforementioned breakage at the palatal suture.
