[Diagnosis and treatment of fibrous adhesion into upper joint compartment of the TMJ. Part 2. Arthroscopic findings and arthroscopic sweeping and lysis].
A fibrous adhesion into upper joint compartment of the TMJ is indicated by a secondary pathological condition of the disk displacement. A fibrous adhesion increases resistance to motion in the joint because condyle translation disrupted. The treatment for this condition is too difficult. On this paper, we presented to arthroscopic findings of 4 cases of the fibrous change and fibrous adhesion into upper joint compartment of the TMJ (1) and arthroscopic sweeping as the treatment procedure (2). On these cases, we compared double contrast arthrotomographic findings with arthroscopic findings (3). (1) On the arthroscopic findings, banddle like fibrous adhesion, wide areal fibrous adhesion, and wide areal fibrous change of the articular surfaces were observed. These findings varied to case by cases. (2) The arthroscopic sweeping and lysis performed on this four cases. The clinical symptoms prior to arthroscopic surgery, improved post surgically in all cases. (3) The fibrous lesions in the upper joint compartment was presumed by double contrast arthrotomography that demonstrated by arthroscopy.
