Mandibular osteotomy

Mandibular osteotomy

General


The mandible is the bone forming the lower jaw. It carries the lower teeth and articulates with the skull by the temporomandibular joint.

The mandibular osteotomy is part of interventions in orthognathicsurgery.

The most used technique is called « sagittal osteotomy of the ascending branche ». The principle is to cut the mandible in the sagittal direction to separate the toothed bone portion of those involving the temporomandibular joints. The occlusion is corrected without changing the position of the mandibular condyles in the joints.


Intervention


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

The incisions are placed inside the mouth, so there is no external scars. The mandible is cut accurately with a device to the ultrasound Piezotome. The toothed portion 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 disadvantages of the mandibular osteotomy are edema of the face for about one month and sometimes a decrease in sensitivity when touching the skin level of the lower lip.


Our opinion


Known for many years, orthognathic surgery 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.
