[Posterior dislocation of the articular disc--a rare case?]

The aim of this paper is to describe a very seldomly observed case of a unilateral dorsal luxation of the disc of the temporomandibular joint. The luxation happened during intense laughing in a movie-theater and was first noticed two days later. The diagnosis of this unilaterally shifted and fixed mandible was clearly seen on the double-contrast arthrogram. The therapy of repositioning the joint was done under short-duration general anaesthesia followed by a 2 weeks immobilisation of the jaws.
