Maxillary stability following Le Fort I osteotomy using Prebent plates and wire fixation in patients undergoing surgery for OSAS

The purpose of this study was to analyze the stability of Le Fort I maxillary advancement in the vertical and horizontal directions using a combination of wire and rigid fixation in patients undergoing surgery to treat obstructive sleep apnea (OSA). Wire osteosynthesis can be performed quicker and at a reduced cost.The lateral cephalograms of 21 patients were evaluated preoperatively (T0), immediately postoperatively (T1), and at least 6 months postoperatively (T2). Four cephalometric points were used to measure movement in the horizontal and vertical directions.
