Case Discussion
Temporomandibular joint ankylosis represents fibrous or bony fusion between the mandibular condyle and fossa, which is usually traumatically caused by condyle fracture. It could also be caused by infections, degenerative diseases, injection of corticosteroids, forceps delivery and complications of TMJ surgery.
It usually develops before 10 of age, however, it could develop at any age.
Patients usually present with progressive limitation of mouth opening, facial deformity, and obstructive sleep apnea syndrome.
