Abstract

TOMAS AMERIGO, José Ángel et al. Synovial cyst of the temporomandibular joint: presentation of a case. Rev Esp Cirug Oral y Maxilofac [online]. 2015, vol.37, n.3, pp.144-147. ISSN 2173-9161.  https://dx.doi.org/10.1016/j.maxilo.2014.02.004.

A synovial cyst located in the temporomandibular joint is rare, with few cases reported in the medical literature. Gaisford et al. were the first authors to report a case of a synovial cyst. This a condition that more frequently affects joints such as the wrist or knee. These cysts are delimited by synovial cells, and may be connected to, or be independent of, the joint cavity. Several theories have been proposed to explain the etiology of this disease: an increase in pressure in the joint cavity caused by inflammation or trauma may be the reason that a herniation of the synovial membrane could be produced. Among the diagnoses to be considered when faced with a tumor are pre-auricular parotid tumors, sebaceous cysts, ganglia and synovial cysts, among others. Surgery is the treatment most frequently proposed in the literature, achieving a low rate of recurrence.
