MRI and arthroscopic findings in the temporomandibular joint after mandibulectomy including the unilateral condyle. Report of two cases.
In this report, the MRI and arthroscopic findings in the temporomandibular joint (TMJ) of two patients who underwent partial mandibulectomy including the condyle are presented. The disc and superior joint compartment of the affected TMJs were preserved in both patients. MRI of the affected TMJs without condyle demonstrated that the intermediate zone of the discs was located anteriorly to the summit of the articular eminence. Joint effusion was detected in the superior joint compartment of one patient. Fibrous adhesions were observed arthroscopically in the superior joint compartment of both affected TMJs. In contrast, no specific findings were demonstrated in the contralateral TMJs connected with the residual mandibular fragment.
