title: Pterygoid plate fracture in Le Fort I osteotomy with and without pterygoid chisel: a computed tomography scan evaluation of 58 patients.
abstract: The incidence of pterygoid plate fracture as determined by computed tomography (CT) scan is much higher than that determined at surgery. This observation is irrespective of whether a chisel is used to effect pterygo-maxillary separation.
