TMJ Forum - right mandibular condylar cyst.

Thanks for understanding Tmddyan.

At this particular point I am being forced to research as my doctors confuse more than help. Here is what I found on pubmed.com; sadly, my university account has expired so no more full access to articles, I will try to regain that feature as I cannot afford to travel to university grounds to have access.
Why can't medical research be free to all, but that's another question...

Temporomandibular joint neoplasms and pseudotumors.
Warner BF, Luna MA, Robert Newland T.

Department of Pathology, University of Texas M.D. Anderson Cancer Center, Houston, USA.

Neoplasms and pseudotumors of the temporomandibular joint (TMJ) are very uncommon. Early recognition of such will prevent therapeutic delay and may have a dramatic impact on patient morbidity and mortality. Included in rare TMJ lesions are the following: 1) synovial chondromatosis, 2) osteochondroma, 3) osteoma, 4) osteoblastoma, 5) pigmented villonodular synovitis, 6) ganglion, 7) synovial cyst, Cool

simple bone cyst, 9) aneurysmal bone cyst, 10) epidermal inclusion cyst, 11) hemangioma, 12) nonossifying fibroma, 13) Langerhans cell histiocytosis, 14) plasma cell myeloma, 15) sarcoma.

Ganglion cyst and synovial cyst of the temporomandibular joint. Two case reports.

Ganglion cysts and synovial cysts are lesions rarely associated with the temporomandibular joint. Ganglion cysts arise from myxoid degeneration of the connective tissue of the joint capsule, are filled with viscoid fluid or gelatinous material, and have a fibrous lining. Synovial cysts also contain gelatinous fluid and are lined with cuboidal to somewhat flattened cells consistent with a synovial origin. One case of a ganglion cyst and one case of a synovial cyst of the temporomandibular joint are presented, and their differential diagnosis and management are discussed.

Benign osteoblastoma associated with an aneurysmal bone cyst of the mandibular ramus and condyle.

This article reviews the clinical behavior, the histologic conditions, and the treatment of a benign osteoblastoma associated with an aneurysmal bone cyst of the mandibular condyle and ramus. A 14-year-old boy, otherwise healthy, was referred for pain and enlargement in his right temporomandibular joint-cheek region. The swelling was firm and tender, a slight facial asymmetry was present, and the mouth-opening capacity was reduced. During a 6-weeks period from the primary examination to surgery the lesion expanded extensively, anesthesia appeared in the right inferior alveolar nerve and a lateral open bite developed on the affected side. Computed tomography displayed a total destruction of the right mandibular condyle and ramus to the level of the mandibular foramen. The lesion was radiolucent without distinct borders to adjacent bone. Surgery revealed a bluish, well-vascularized predominantly cystic tumor. The lesion included the temporomandibular joint disk but without overgrowth to the temporal component. After resection of the lesion, the condyle and the mandibular ramus was reconstructed with the use of an autogenous costochondral graft. The postoperative healing was uncomplicated. At follow-up 2 years after surgery the boy was free of recurrence with normal motor and sensory nerve function.

Temporomandibular joint clicking noises caused by a multilocular bone cyst: a case report.
Ozçelik TB, Ersoy AE.

University of Ankara, Faculty of Dentistry, Turkey.

When diagnosing patients with temporomandibular disorder (TMD) symptoms, the possibility of unusual causes must be considered, including neoplastic disorders, as well as infections and inflammatory disease. Therefore, radiologic examination may prove to be invaluable in the differential diagnosis of TMDs. This article describes a patient whose temporomandibular joint (TMJ) noise was initially diagnosed by another dental clinic as a TMJ anterior disc displacement with reciprocal clicking. Occlusal splint therapy was used for nearly three to four months but did not improve the TMJ noise condition. When the patient was examined clinically and imaged with magnetic resonance imaging (MRI) and computed tomography (CT), a multilocular bone cyst (MBC) was suspected. The cyst could cause surface irregularities in the posterior part of the left eminence of the temporal bone, which could be the source of the clicking noise.

Ganglion cyst of the temporomandibular joint.

We report a case of cystic lesion in a 37-year-old woman. The patient had an oval-shaped lesion adjacent to the temporomandibular joint. Thick fibrotic tissue and muscle were observed microscopically, but the epithelium lining was not observed. The lesion was diagnosed as a ganglion cyst. The patient's general medical history was non-contributory. High performance liquid chromatography (HPLC) and mass spectrophotometry (MS) revealed some proteins from the fluid in the lesion, such as a filaggrin precursor, dystroglycan, a polyprotein of the hepatitis C virus, and proteins originating from bacteria. The follow-up examinations revealed no recurrence. The probable pathogenesis of the lesion is discussed.

Recognizing the temporomandibular joint ganglion.
Kenney JG, Smoot EC, Morgan RF, Shapiro D.

A case report of a cystic preauricular mass that changed in size and position with jaw movement is presented. This tumor proved to be a ganglion of the temporomandibular joint (TM) cyst, which is relatively rare. When a preauricular mass retrudes into the masseter muscle in jaw opening, pathological conditions associated with the TMJ should be considered. Ganglion cysts of the TMJ are a benign pathological entity which can mimic parotid tumors. Temporomandibular joint radiography and perhaps ultrasonography of the region are useful in the preoperative evaluation of preauricular masses. The TMJ ganglion cyst can be successfully treated by direct excision and repair of the joint capsule. This approach avoids the potential morbidity of a superficial parotidectomy.

Abstract

Loss of bony integrity of the temporomandibular joint may result in prolapse of the joint capsule into the external auditory canal. This in turn gives rise to arthralgia, trismus and earache and a risk of septic arthritis.

We describe a technique of repair which is simple, uses autologous tissue and has an acceptable cosmetic and functional result.

Abstract

A rare case of simple bone cyst in the mandibular condyle of a 33-year-old woman is reported. The condition was difficult to diagnose because the cyst was accompanied by severe osteoarthritis. T1-weighted magnetic resonance (MR) images revealed a cystic lesion with intermediate signal intensity within the condylar head and an irregular margin with intermediate signal intensity on the superior surface of the condyle. The patient was treated by high condylectomy, discectomy and reconstruction by sagittal split ramus osteotomy. Histopathological examination showed a simple bone cyst in the condylar head and erosion of the anterior articular surface due to degenerative changes.
