Pseudoankylosis of the mandible as a result of methyl methacrylate-induced inflammatory cicatricial contracture of the temporal muscle after cranioplasty.

Pseudoankylosis of the mandible after intracranial surgical procedure has been widely reported, and is usually caused by fibrosis of the temporal muscle as a result of injury during the operation. We present an unusual case of mandibular pseudoankylosis as a result of methyl methacrylate-induced aseptic inflammatory cicatricial contracture of the temporal muscle after cranioplasty.
