title: Vital staining of palatal soft tissue in horseshoe Le Fort I osteotomy for superior repositioning of the maxilla.
abstract: In maxillary orthognathic surgery, superior repositioning of the maxilla is sometimes difficult, and removal of the bony interference, especially around the descending palatine artery, is very time-consuming in cases of severe maxillary impaction. A useful method introduced for superior repositioning of the maxilla is horseshoe-shaped osteotomy combined with Le Fort I osteotomy (horseshoe Le Fort I osteotomy). However, injury to the palatal soft tissue during horseshoe-shaped osteotomy may cause aseptic complications of the maxilla. Therefore, a safe method is required to prevent such injury to reduce the risk for aseptic necrosis. We describe here vital staining of palatal soft tissue in horseshoe Le Fort I osteotomy for safer superior repositioning of the maxilla.
