Which of the following type of Le Fo fracture is known as craniofacial disjunction?
Correct Answer: Le Fo III
Description: Le Fo I fractures occur transversely across the alveolus, above the level of the teeth apices. In a pure Le Fo I fracture, the palatal vault is mobile while the nasal pyramid and orbital rims are stable. The Le Fo II fracture extends through the nasofrontal buttress, medial wall of the orbit, across the infraorbital rim, and through the zygomaticomaxillary aiculation. The nasal dorsum, palate, and medial pa of the infraorbital rim are mobile. The Le Fo III fracture is also known as craniofacial disjunction.
