CONCLUSION

Arthrocentesis of the temporomandibular joint is a minimally invasive treatment method at the boundary between conservative and surgical therapy. It is usually performed on an out-patient basis under local anaesthesia. It is used both in cases of acute block caused by displacement of the articular disc and also to treat degenerative inflammatory diseases of the joints. The main objective of arthrocentesis is to wash out inflammatory mediators, release the disc, break adhesions, eliminate pain and improve joint mobility. It is a method with a minimum number of complications, it is simple and not demanding in terms of instruments, and it can be performed repeatedly. For this reason, it has become widespread and very popular in the treatment of internal disorders of the temporomandibular joint.
