Diagram of a Le Fort III osteotomy

The Le Fort III osteotomy is a surgical procedure used to correct midface deformities. It is one of the three classic Le Fort osteotomies, which are named after the French surgeon René Le Fort, who described the fracture patterns in the early 20th century. The Le Fort III osteotomy involves the detachment and repositioning of the midface, including the zygomatic bone, maxilla, and the nasal bones, to correct congenital or acquired deformities.

Indications

The Le Fort III osteotomy is primarily indicated for patients with midface hypoplasia, which can occur in conditions such as Crouzon syndrome, Apert syndrome, and other craniofacial dysostoses. It is also used in cases of severe maxillary retrusion and in some instances of obstructive sleep apnea where the midface is underdeveloped.

Surgical Technique

The procedure involves making incisions in the oral cavity and sometimes on the face to access the bones of the midface. The surgeon then carefully separates the midface from the skull base, allowing it to be repositioned forward. This advancement can be stabilized using titanium plates and screws. In some cases, bone grafts may be used to fill gaps and ensure proper healing.

Postoperative Care

After a Le Fort III osteotomy, patients typically require a hospital stay for monitoring and pain management. Swelling and bruising are common, and patients may need to follow a soft diet for several weeks. Regular follow-up appointments are necessary to monitor healing and ensure that the bones are properly aligned.

Complications

As with any major surgery, there are potential complications associated with the Le Fort III osteotomy. These can include infection, bleeding, and adverse reactions to anesthesia. There is also a risk of nerve damage, which can lead to numbness or altered sensation in the face. Long-term complications may include relapse of the deformity or issues with occlusion.
