Abstract:
Repositioning osteotomies in a Le Fort I fashion can affect the position of the TMJ, which cannot be viewed directly during surgery. Using the computer-assisted navigation system SSN (Surgical Segment Navigator), the intraoperative position of the TMJ can be checked and unintentional malpositions can be detected. Positioning of the maxilla after Le Fort I osteotomy was carried out in a conventional fashion. Afterwards, the position of the maxilla was corrected in the same patients using the SSN. In this way, the precision of conventional and SSN-guided positioning of the maxilla and its effect on the TMJ has been compared.
