A case of pseudoankylosis between the pterygoid plate and mandible

There are many causes of limitation of mandibular function. The use of CT scanning has enhanced our ability to look beyond the more obvious anatomic areas of mandibular ankylosis. An interesting case of pseudoankylosis of the pterygoid plate and mandible is presented. This case clearly demonstrates the importance of CT scanning in the diagnosis and treatment planning for such an unusual anomaly.
