Maxillary osteotomy

Maxillary osteotomy

General


The maxillary bone forms the upper jaw. It participates in the facial bones.

The maxillary osteotomy is part of interventions in orthognathicsurgery.

The most used technique is called « Lefort I osteotomy ». The principle is to cut the jawbone horizontally at the maxillary sinus and the lower portion of the nasal cavity.


Intervention


The maxillary Lefort I osteotomy occurs during a hospital stay of several days. It is performed under general anesthesia.

The incisions are placed inside the mouth, under the lip superieure. There are no external scars. The jawbone is cut accurately with a device to the ultrasound Piezotome. The upper jaw is then repositioned and fixed by the small plates and screws entirely integrated with the bone.

The incisions are closed with absorbable sutures.

In some cases, the mandibular osteotomy may be associated with genioplasty.


Postoperative periods


The hospital stay lasts a few days.

Power must be soft for about 6 weeks, the bone healing time.

A work stoppage of one month is required.

The main disadvantage of the maxillary osteotomy Lefort I is facial edema for about 1 month.


Our opinion


Known for many years, orthognathicsurgery is now a well codified treatment. The improvement in functional terms is well established. It also provides a harmony of facial aesthetics by rebalancing the face and slows the signs of facial aging.
