Pterygoid plate fracture in Le Fort I osteotomy with and without pterygoid chisel: a computed tomography scan evaluation of 58 patients.
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.
