Arthroscopic diagnosis of perforation and adhesions of the temporomandibular joint: correlation with postmortem morphology.
Arthoscopy was performed in the upper joint compartment of 28 temporomandibular joints in 16 fresh cadavers to investigate the accuracy of arthroscopic diagnoses of perforation and adhesion. Subsequent dissections revealed that only three of nine perforations were seen arthroscopically and that three of four joints with adhesions were arthroscopically diagnosed. There was no overdiagnosis of perforation or adhesions. Intra-articular hyperplastic soft tissue formation (crab meat) was arthroscopically seen in ten joints (36%) and was with only two exceptions associated with either a perforation or adhesions. Histologically, the adhesion and the hyperplastic soft tissue consisted of fibrous connective tissue with collagen fibers and fibroblasts. It was concluded that a positive arthroscopic diagnosis of adhesion or perforation is reliable whereas a negative diagnosis of perforation is not reliable.
