1/56. Synovial chondromatosis of the temporomandibular joint.We report two cases of temporomandibular joint (TMJ) synovial chondromatosis, one of which was in the early stage and treated arthroscopically. The second was more advanced and recurred after removal of the free bodies, and so required condylectomy and synovectomy.- - - - - - - - - - ranking = 1keywords = chondromatosis, synovial chondromatosis (Clic here for more details about this article) |
2/56. Synovial chondromatosis of the temporomandibular joint: varying presentation in 4 cases.Synovial chondromatosis is a rare condition in which cartilage is formed in the synovial membrane of a joint. The manifestations of this benign neoplastic process can mimic many common temporomandibular joint and parotid diseases. Four cases of synovial chondromatosis are presented. In each case, atypical presentation, coexisting joint disease, or both caused diagnostic confusion. The histories and physical examinations were initially consistent with more common joint diseases in each case. Imaging provided some insight into diagnosis and was a definitive indication for surgical treatment. Treatment by subtotal synovectomy and by removal of chondromatous nodules were undertaken in each case. No patient in our series has had recurrence of disease or symptoms after surgical treatment.- - - - - - - - - - ranking = 1.1711159327589keywords = chondromatosis, synovial chondromatosis (Clic here for more details about this article) |
3/56. Synovial chondromatosis of the left temporomandibular joint superficially resembling chondrosarcoma: a case report.A 25 year-old woman was referred to the clinic complaining of pain in the left temporomandibular joint (TMJ) and trismus. According to the x-ray images, a solitary mass was observed in the anterior pouch of the lower joint cavity. The mass was removed by means of a synovectomy and a diskectomy. Upon light microscopic examination, the tissue removed showed high cellular activity. As a differential diagnosis, we had to consider the possibility of chondrosarcoma based on the histopathological features; however, since no invasive nor metastatic finding was recognized, we made a diagnosis of synovial chondromatosis despite its rare existence. Although there has been no sign of recurrence at present, we plan to carefully follow up with the patient.- - - - - - - - - - ranking = 1keywords = chondromatosis, synovial chondromatosis (Clic here for more details about this article) |

Synovial chondromatosis in the temporomandibular joint complicated by displacement and calcification of the articular disk: report of two cases.Two cases of synovial chondromatosis of the temporomandibular joint (TMJ) are presented, including correlation of CT and MR imaging characteristics with surgical and pathologic findings. The usefulness of CT and MR imaging in the diagnosis of TMJ disorders is discussed.- - - - - - - - - - ranking = 1keywords = chondromatosis, synovial chondromatosis (Clic here for more details about this article) |
5/56. Condylar hyperplasia associated to synovial chondromatosis of the temporomandibular joint: a case report.Condylar hyperplasia is a slowly developing malformation of the mandible, with elongation of the mandibular neck, that generally results in facial asymmetry. Synovial chondromatosis is a benign chronic disorder characterized by the formation of multiple small nodules of hyaline cartilage as a result of metaplasia of the synovial connective tissue. It affects mostly the large joints, particularly the knee, hip, elbow and ankle. The temporomandibular joint (TMJ) is rarely affected. The case of a 42-year-old male with a history of left preauricular pain and swelling and deviation of the mandible to the left upon opening the mouth is presented. Computed tomography disclosed hyperplasia of the left condyle with loose radiopaque bodies within the joint cavity. The left TMJ was subject to open surgery, which included resection of four loose bodies and a remodeling condylectomy. The histopathological study confirmed the diagnosis of condylar hyperplasia and chondromatosis of the left TMJ.- - - - - - - - - - ranking = 1.604376941375keywords = chondromatosis, synovial chondromatosis (Clic here for more details about this article) |
6/56. A case of synovial chondromatosis of the TMJ: treatment based on stage of the disease.A patient with synovial chondromatosis of the temporomandibular joint extending to the preauricular skin, parotid, and infratemporal fossa was operated and followed with a stable remnant, for 2 years postoperatively. In light of literature and what the authors have learned from this case, the authors emphasize stage of the disease as a risk factor for recurrence. The long history of symptoms, calcified and conglomerated radiological appearance of the lesion, and extensive involvement of the joint and periarticular area of this case indicate a late-stage disease in which the metaplastic activity dwindles. For late stages, the authors suggest a conservative approach that will only provide symptom relief and prevent secondary joint deformity to avoid potential complications and morbidities of a more extensive surgery.- - - - - - - - - - ranking = 1.5776813448214keywords = chondromatosis, synovial chondromatosis (Clic here for more details about this article) |
7/56. Arthroscopic removal of nodules of synovial chondromatosis of the temporomandibular joint.In this report we describe a new method for removing nodules of TMJ synovial chondromatosis using arthroscopic surgery instead of open surgery. We used two steps during arthroscopy. In the first, we lavaged the cavity with sterile saline. In the next step, the second cannula was replaced with ethmoid forceps. Under arthroscopic guidance through the first cannula, all loose bodies were removed using the forceps. Since the loose bodies are not fragmented during this procedure, the time needed for removal is shortened. Based on this experience, we suggest the use of ethmoid forceps should be considered as an alternative procedure when nodules are unable to pass through the cannula by lavage with sterile saline.- - - - - - - - - - ranking = 1.5776813448214keywords = chondromatosis, synovial chondromatosis (Clic here for more details about this article) |
8/56. The expression of fibroblast growth factor-2 and fibroblast growth factor receptor-1 in chondrocytes in synovial chondromatosis of the temporomandibular joint. report of two cases.Synovial chondromatosis (SC) is a rare, benign condition characterized by the formation of metaplastic cartilaginous nodules. The expression of fibroblast growth factor-2 (FGF-2) and fibroblast growth factor receptor-1 (FGFR-1) in two cases of SC of the temporomandibular joint (TMJ) were immunohistochemically studied. The possible roles of FGF-2 and FGFR-1 in SC of the TMJ are discussed.- - - - - - - - - - ranking = 1.433261008616keywords = chondromatosis, synovial chondromatosis (Clic here for more details about this article) |
9/56. Synovial chondromatosis of the temporomandibular joint: long-term postoperative follow-up of the residual calcification.Synovial chondromatosis of the temporomandibular joint is a rare disease, and extra-articular synovial condromatosis of the temporomandibular joint is even rarer. A review of the English literature from 1980 to 2000 has revealed 51 cases of synovial chondromatosis affecting the temporomandibular joint. We report a case of extra-articular synovial condromatosis, for which we carried out a long-term follow-up of the postoperative course using diagnostic images.- - - - - - - - - - ranking = 1.1711159327589keywords = chondromatosis, synovial chondromatosis (Clic here for more details about this article) |
10/56. Synovial osteochondromatosis accompanying an ossified articular disk in the temporomandibular joint: a case report.A 51-year-old woman was referred for pain in the right temporomandibular joint (TMJ) and the trismus. Conventional radiography showed a radiopaque area in the disk, which suggested calcification. At surgery, multiple, round-to-ovoid cartilagenous nodules were found in the joint cavity. Synovectomy and diskectomy were carried out via a pre-auricular incision to remove the nodules. Examination under light microscopy confirmed the diagnosis of synovial osteochondromatosis (SOC). The disk contained a large ossified mass. To our knowledge, this is the first reported example of SOC accompanied by ossification of a large part of the disk.- - - - - - - - - - ranking = 0.91404271930064keywords = chondromatosis, synovial osteochondromatosis, osteochondromatosis (Clic here for more details about this article) |
