Chondrosarcoma of the head and neck region is a rarely encountered tumor. Aggressive surgical excision offers the best chance for cure. In our case, combined diagnostic techniques consisting of fine needle aspiration (FNA), computed tomography (CT), and magnetic resonance imaging (MRI) made an accurate preoperative assessment possible and greatly influenced the treatment provided. 相似文献

The occlusal problems and the temporomandibular disorders are the most frequent aspects which we often find to the patients with the dysfunctional syndrome of the stomatognathic system. This study tries to establish the correlation between these two kinds of dysfunctions and to find (if it exists) a direct proportional relation between them. For this purpose we studied 8 cases who had been diagnosed as having the dysfunctional syndrome of the stomatognathic system on the base of the clinical symptoms, tomographs and CT. The results of the study proved that an occlusal dysfunction can affect the temporomandibular joint and vice versa, because all the component parts of the stomatognathic system are in a close relationship and they influence each other, but these results didn't indicate a direct proportional relation between these two kinds of dysfunctions. 相似文献

The eighth known case of pigmented villonodular synovitis of the temporomandibular joint is presented. Pigmented villonodular synovitis is a benign but locally destructive lesion of obscure cause. In the temporomandibular joint, this lesion is characterized by the insidious onset of a mildly symptomatic preauricular mass. The treatment of choice is complete excision. 相似文献

Synovial cell sarcoma is a relatively rare tumor of mesenchymal origin. It is a high-grade neoplasm that microscopically shows a monophasic or biphasic cellular pattern and includes epithelial features as well as supporting tissue features. Surgical excision is the primary mode of treatment. Postoperative radiotherapy and chemotherapy also is seen to be helpful. Between 3% and 10% of cases originate in the head and neck. A review of relevant literature shows less than 10 cases of synovial cell sarcoma of the temporomandibular joint area reported in the English literature. We report an additional case of biphasic synovial cell sarcoma arising in the temporomandibular joint area, which caused ear pain, tinnitus, and hearing loss, and we further discuss the clinical features, histopathology, differential diagnosis, and treatment modality. 相似文献

A new surgical technique has been developed to combine arthroscopic laser surgery with suturing to be used clinically in the treatment of temporomandibular joint disorders. This new technique involves the use of a recently invented double-channel cannula needle scope to visualize the lesion. Subsequently, we combined Nd-YAG laser with suturing in the cavity in order to treat the area around the intraarticular wall. The primary use of arthroscopic laser surgery is for treatment of lesions in the inner wall of the joint cavity. In this article, we give an outline of both the arthroscopic laser surgery and the arthroscopic suturing as well as the clinical, postoperative results of these cases. 相似文献

Vascular malformation of the temporomandibular joint: report of a case and review of the literature.
Shelly Abramowicz Chadwick J Marshall M Franklin Dolwick Donald Cohen 《Oral surgery, oral medicine, oral pathology, oral radiology, and endodontics》2007,103(2):203-206
The diagnosis and treatment of vascular anomalies is extremely challenging because of inconsistent terminology and classification systems, as well as nonspecific clinical and radiological findings. We report a vascular malformation that was treated successfully via resection, and reconstructed using a custom-made temporomandibular joint fossa and condylar prosthesis by TMJ Concepts. The available pertinent literature is also reviewed. 相似文献

A case of traumatic mandibular fracture with associated unilateral anterior dislocation of the temporomandibular joint in a child is described. Although anterior dislocation is common, this combination of fracture and separate dislocation to our knowledge has not been reported in a young child. The unusual management required in this case is discussed. 相似文献

OBJECTIVE: The objective of the study was to compare findings from ultrasonography (US) of the temporomandibular joint (TMJ) in patients with rheumatoid arthritis (RA), psoriatic arthritis (PsA), and temporomandibular disorders (TMD). STUDY DESIGN: US assessment of the temporomandibular joints was bilaterally performed in 68 patients (22 with RA, 11 with PsA, and 35 with TMD). All the TMJs were assessed for the presence of disc displacement, effusion, and changes of the condylar profile, and the prevalence of such abnormalities was compared across the 3 groups of patients. To confirm generalizability of results, US findings were also compared with those of magnetic resonance (MR), taken as the standard of reference. RESULTS: Prevalence of disc displacement and changes in condylar profile were similar between patients with rheumatic diseases and temporomandibular disorders, while effusion was significantly more present in TMJs of TMD patients. Sensitivity of US to detect TMJ abnormalities was acceptable, while specificity was low for condylar alterations. CONCLUSIONS: Temporomandibular joint involvement in patients with rheumatic diseases seems to be similar to that described in subjects with temporomandibular disorders. Ultrasonography confirmed to be an accurate technique to detect disc displacement and effusion within the temporomandibular joint, but not to detect condylar abnormalities. 相似文献

Temporomandibular joint ankylosis which is most frequently caused by trauma, presents with restriction in mouth opening in early stages and if children are the victim and not treated early, it presents with growth retardation of the involved mandibular side. Various methods are available for surgical correction. We have reviewed our experience with the efficacy of different interpositional materials in post-traumatic cases in our set up with special reference to temporal fascia over last three years. Twenty seven patients with history of trauma, mostly fall from height, have been studied. They were evaluated clinically and by computed tomography (CT) scan, orthopantogram and x- ray lateral oblique view. The most common age group was 10-15 years with mean 12.5 years and male to female ratio 1:2. Preoperative mouth opening (inter incisor distance) was 1-2 mm in 17 cases and 2-4 mm in 10 cases. We have used temporalis fascia in nine, costochondral graft in seven, silastic sheets in five and T-plates in six cases. Post-operatively, adequate mouth opening of 30-50 mm was observed in six months follow-up and more than 50 mm at one year follow up in 21 cases out of which nine cases have interpositional material as temporalis fascia alone. The postoperative period was uneventful in all cases and none required re-operation for recurrences. We conclude that interpositional arthroplasty, especially with pedicled temporal fascia, is the best method to prevent recurrences and establish good mouth opening and full range of jaw movements. 相似文献
