Resumen de Importance of early arthrocentesis in temporomandibular joint closed lock by disc displacement without reduction. A case review
Jordi Borrás Ferreres, Cosme Gay Escoda
Arthrocentesis (joint lysis and lavage) and hydraulic distension with manipulation of the temporomandibular joint have been described as effective options for reducing joint pain and improving function in patients with limited mouth opening (closed lock) due to disc displacement without reduction, fundamentally in the acute phase of the disorder. However, the efficacy and scientific basis of such treatment have not been validated to date. As a result, the most frequent management strategies tend to be more conservative and mainly focus on the use of nonsteroidal antiinflammatory drugs and/or muscle relaxants, occlusal splints and physiotherapy.
The present study was carried out to assess the efficacy of early arthrocentesis in improving mouth opening and reducing joint pain in a woman with a 10-day history of acute closed lock due to left temporomandibular joint disc displacement without reduction.
