Diskectomy of the temporomandibular joint: a double-contrast arthrotomographic follow-up study.

Abstract

The manner in which temporomandibular joint soft-tissue structures remodel following diskectomy has been assessed by double-contrast arthrotomography. Pre- and postoperative arthrograms were compared in ten joints. The intra-articular soft-tissue cover of the bony components was frequently thicker 1 to 3 years after the operation. The most pronounced thickening was observed in the mandibular fossa, whereas a thinner cover was found on the condyle and the tubercle. Development of a thick soft-tissue cover on the articulating surfaces indicates that the temporomandibular joint has a capacity articulating surfaces indicates that the temporomandibular joint has a capacity for functional adaptation following diskectomy. This may be an essential factor for a favorable postoperative result.
