Study Notes
Le Fort Fracture Classifications
-
Le Fort Type I
- Known as "floating palate" and classified as a horizontal fracture.
- Separates the teeth from the upper face.
- Fracture line follows the alveolar ridge, lateral nasal area, and inferior wall of the maxillary sinus.
-
Le Fort Type II
- Referred to as "floating maxilla" with a pyramidal shape.
- Features a fracture where teeth form the base of the pyramid and the nasofrontal suture is at the apex.
- Fracture line extends through the posterior alveolar ridge, lateral walls of maxillary sinuses, inferior orbital rim, and nasal bones.
- Upper fracture line may intersect with the nasofrontal junction or the frontal process of the maxilla.
-
Le Fort Type III
- Known as "floating face" and described as a transverse fracture.
- Characterized by craniofacial disjunction, affecting the stability of facial structures.
- Involves a fracture line that passes through the nasofrontal suture, maxillo-frontal suture, orbital wall, and zygomatic arch/zygomaticofrontal suture.
- The involvement of the zygomatic arch heightens the risk of temporalis muscle impingement.
- Notably has the highest incidence of cerebrospinal fluid (CSF) leak compared to other types.
