Surgical strategy for long-standing dislocation of the temporomandibular joint: experience with 16 medically compromised patients.

We evaluated the surgical outcomes in 16 patients with long-standing dislocation of the temporomandibular joint (TMJ): eight men and eight women, mean (range) age 72 (21-94) years. They all had multiple underlying diseases, either dementia or a mental disorder, and the joint had been dislocated for four weeks or longer. Manual reduction had been ineffective.

A modified approach for eminectomy for temporomandibular joint dislocation under local anaesthesia: report on a series of 50 patients.

Conventional eminectomy for habitual dislocation of the temporomandibular joint is usually performed under general anaesthesia. This technique was modified for use under local anaesthesia to treat medically compromised patients. Fifty elderly patients (90 joints) were treated, for whom general anaesthesia was considered a serious risk due to systemic diseases; the dislocation was habitual in 39 and long-standing in 11.

Ganglion cyst in the temporomandibular joint: A case report and discussion of surgical approaches.

Ganglion cysts in the temporomandibular joint are treated by resection; however, there has been insufficient discussion regarding the appropriate approach for surgical resection. A 55-year-old man presented with a left preauricular swelling for one year. The examination revealed a moderately hard mass with a 30-mm diameter, tenderness, and restricted movement.

Tethering technique using bone screws and wire for chronic mandibular dislocation: a preliminary study of refractory cases.

A retrospective study was performed to determine the efficacy of a tethering procedure developed to achieve a more rigid fixation and more reliable outcome in patients with refractory dislocation of the temporomandibular joint. The cases of eight patients with dementia and systemic diseases who underwent this technique were reviewed. In these eight patients, the condyles of 13 joints were ligated using wire between screws placed in the eminence and condylar head.

Expression of Sphingosine Kinase-1 Is Associated with Invasiveness and Poor Prognosis of Oral Squamous Cell Carcinoma.

Background/aim: The expression of sphingosine kinase-1 (SphK1) has been reported in several cancers. However, the exact roles of SphK1 in cancer progression still remain unknown. The aim of the present study was to investigate SphK1 expression in oral squamous cell carcinoma (OSCC) and clarify the involvement of SphK1 in the proliferation and invasiveness of OSCC and its prognostic implications.
