A stuck disc, also called anchored disc phenomenon, refers to a temporomandibular joint (TMJ) disc which does not translate anteriorly out of the mandibular fossa onto the articular eminence but rather remains (thus "stuck") in the fossa. It is a form of TMJ dysfunction.
Patients may experience a sudden, severe, inflexible and persistent restriction of mouth opening. They may be deviation of the mandibular midline toward the affected side with limited movements (0 - 10 mm). No pain in the masticatory muscles or the joints is often reported.
Plain radiograph and CT
normal temporomandibular joint
during mouth opening, the condylar process rotates in the region of the fossa with no evidence of sliding down the slope of the eminence.
Arthrography
Normal shaped disc.
MRI
Sticking of the disc to the mandibular fossa.
Treatment is with arthroscopic adhesionectomy.
