What type of facial fracture is classified as LeFort I?

  1. Nasal fracture

  2. Maxillary fracture, straight

  3. Frontal fracture

  4. Orbital fracture

The correct answer is: Maxillary fracture, straight

LeFort I fractures are specifically classified as horizontal maxillary fractures. This type of fracture involves the separation of the maxilla from the base of the skull, typically creating a fracture line that is transverse across the maxillary area, just above the upper teeth. The occurrence of a LeFort I fracture often results from significant trauma, such as a motor vehicle accident or a severe blow to the face. The fracture is characterized by the displacement of the maxilla, which can lead to mobility of the dental arcade and potential disruption of the anterior nasal spine. This injury must be identified and managed appropriately to avoid complications such as malocclusion or airway obstructions. The other choices reflect different types of facial injuries. Nasal fractures pertain only to the nasal bones without involving the maxilla. Frontal fractures specifically involve the frontal bone of the skull, while orbital fractures relate to injuries to the bones surrounding the eye. Understanding these distinctions is essential for clinicians in diagnosing and effectively treating facial fractures.
