Synovial Cyst of the Temporomandibular Joint: Report of a case.

Synovial cyst of the temporomandibular joint: A case report and literature review

“…Synovial cysts seem to be caused by an increase in intra-articular pressure due to trauma 3,6,7,10 or to an inflammatory process (rheumatoid arthritis, osteoarthritis or synovitis 2 ), which causes a capsular herniation of the TMJ into the surrounding tissues. A displacement of synovial tissue during embryogenesis 5 and an abnormal force on the joint resulting from a dysfunction of the TMJ have also been reported as possible causes 4 .…”

“…Treatment of synovial cysts generally consists of surgical excision of the TMJ herniated capsule using a preauricular approach [3][4][5][6][7][8][9][10] . A conservative arthroscopic surgical technique, which limits disruption of the TMJ capsule and identifies and treats the causative disease (it performs joint lavage and injects anti-inflammatory medications) has also been suggested 2 .…”

“…Synovial cysts rarely occur in the region of the temporomandibular joint (TMJ) 4 . They are usually present on the extensor surface of the wrist and to a lesser extent on the dorsal surface of the foot and lateral aspect of the knee 1 .…”

“…They are usually present on the extensor surface of the wrist and to a lesser extent on the dorsal surface of the foot and lateral aspect of the knee 1 . Only 10 synovial cysts in the region of the TMJ have been reported 2-10 . In the literature, the therapy most frequently suggested is surgical excision of the synovial cyst [2][3][4][5][6][7][8][9][10] . A high success rate has been reported 8 .…”

Auriculotemporal Neuralgia Secondary to TMJ Synovial Cyst: A Rare Presentation of a Rare Entity

“…Synovial cysts of the temporomandibular joint (TMJ) are rare, and to our knowledge, only 14 case reports exist to date . The initial presentation is varied, though local pain, tenderness, and swelling are the most frequent presenting symptoms.…”
