LeFort fracture

Orthopedics A bilateral fracture of the maxilla, which is divided into 3 types, defined by R LeFort in 1901
LeFort fractures  
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
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
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

Zygomatic and lefort fractures accounted for most of the isolated midfacial fractures which is in accordance with previous studies conducted in Lahore and international studies but it is in contrast with a regional study conducted in Rawalpindi, Pakistan.
Oral intubation per se interferes with checking the dental occlusion, while nasotracheal intubation is usually contraindicated in the presence of nasal bone fractures present in isolation or as a component of LeFort fractures.
External compression of a nasotracheal tube due to the displaced bony fragments of multiple lefort fractures.
Nasotracheal intubation was clearly contraindicated because of Lefort fractures.
