Autografting Le Fort I

Purpose: We present a surgical technique for maxillary auto-bone grafting complementary and simultaneously to Le Fort I orthognathic surgery that was used on 123 patients. This graft has two main objectives: to reduce the dead space between the two bone parts of the maxilla and increase the volume of the cheeks, para-nasal spaces or cheekbones to improve the aesthetic result of the intervention.

Methods: From 2007 to 2012, 123 patients underwent a Le Fort I surgery with the conventional technique of Bell. Bone debris collected during the intervention were then wrapped in a sheet of Surgicel® and then grafted at the dead space left in the osteotomy by maxillary movement, or on the anterior maxilla in the paranasal area or on the malar bone. The records of 80 patients were collected to evaluate the postoperative course and 29 postoperative scans were studied to measure the size of the bone pieces.

Results: The postoperative course was uneventful in 93.5% of cases. Seven cases or 8.4% of patients had a postoperative maxillary persistent edema. One case (1.2%) presented a sinus infection without any etiology determined.

Conclusion: This technique, simple and easy, to use allows improved bone healing and cosmetic results without causing excess morbidity. It seems to be a good alternative to bone grafting technique sometimes long and complicated. It can be applied to all Le Fort I osteotomy.
