Maxillary fractures are generally clinically typed by LeFort, and can be divided into three types: Type I: i.e., horizontal fracture of the base of the alveolar process, with the fracture line passing through the inferior border of the pyriform foramen, the base of the alveolar process, and around the alveolar ridge of the crown and the maxillary tubercle backward to the pterygoid process.Type II: i.e., maxillary central conical fracture, with the fracture line running from the root of the nose to both sides, passing through the lacrimal bone and infraorbital rim, the zygomaticomandibular suture, and around the lateral wall of the maxilla, backward to the pterygoid process.Type III: That is, a high-risk horizontal fracture in which the fracture line passes through the nasofrontal suture, across the orbital region, and then downward through the zygomaxillary suture posteriorly to the pterygoid process, creating a craniofacial separation.
