Le Fort fractures should not be confused with Lefort osteotomies. Theese fractures are disjunctions happening frequently in accidents that involve human face. Maxillofacial doctors perform deliberately Lefort fractures on patiens who are undergoing a jaw surgery, in order to reposition the upper jaw (maxilla)

Classification[edit | edit source]

  • Lefort frecture I Dentoalveolar dysjunction Fracture lines are transverse through the pyriform aperature above the alveolar ridge and pass posteriorly to the pterygoid region; the diagnosis is suggested by lip lacerations, clinical malocclusion, mobility of the fractures bone when the examiner moves the incisor teeth
  • Lefort fracture II Pyramidal fracture Superior fracture lines are transverse through the nasal bone and/or maxillary articulation; diagnosis is suggested by free mobility of anterior maxilla
  • Lefort fracture III Craniofacial dysjunction Central third of face is separated from base of skull; diagnosis is suggested by major facial edema, ecchymosis, and facile mobility of middle third of face by examiner; LeFort III is the most severe midfacial fracture, and may require open reduction and internal fixation Sabiston, Ed, Textbook of Surgery, 14 th ed, WB Saunders, 1991 [1]
