Evaluation of a swan's neck osteotome for pterygomaxillary dysjunction in the Le Fort I osteotomy.
The incidence of pterygoid plate fractures resulting from pterygomaxillary dysjunction with a swan's neck osteotome has been determined in a study on cadavers. Fractures did occur at the level of the osteotomy cut but were less frequent than found in a previous study using a conventional curved pterygoid chisel.
