Pseudoankylosis Between Lateral Pterygoid Plates and Mandible: Report of one case

Temporomandibular joint (TMJ) ankylosis is the abnormal fusion of TMJ anatomical components that impedes free jaw movements. This restriction in motion ranges from minimal to complete inability to open the jaw. 1 This condition can be categorized into true or false categories in which true ankylosis is attributed to pathological conditions of the TMJ, whereas false ankylosis (Pseudoankylosis) is applied to restrictions of movement resulting from extracapsular abnormalities outside the TMJ. 2-3 Literature reveals that trauma is the first leading cause of temporomandibular joint disorder (TMD).
