Long-Term Pterygomandibular Ankylosis: Rare Presentation.

Pterygomandibular ankylosis describes a type of pseudo-ankylosis where any part of the coronoid process or TMJ structures is connected to sphenoid bone by a bone bridge. It is a rare presentation of extra-articular temporomandibular joint ankylosis.
