What does double-jaw surgery (BSSO + Le Fort I) involve?

Double-jaw surgery combines two osteotomies: a Le Fort I osteotomy to reposition the upper jaw (maxilla) and a bilateral sagittal split osteotomy (BSSO) to reposition the lower jaw (mandible). The bones are moved into their corrected positions and secured with rigid fixation using titanium plates and screws. This procedure addresses functional issues like malocclusion and sleep apnea, as well as facial asymmetry. The surgery is performed under general anesthesia and typically requires a hospital stay of 7–10 days.
