Long-term evaluation following temporomandibular joint arthroscopy with lysis and lavage

Temporomandibular Joint Arthroscopy

“…A significant maintained decrease in VAS score was achieved after 6 months and also after 5 years follow-up. A significant and maintained improvement in MIO was also observed over the same period of time (Leibur et al, 2010).The results are comparable to those reported in the other papers (Sorel and Piecuch, 2000;Smolka and Iizuka, 2005). It is important to take into account that the sympathetic and sensory nerve fibres within the temporomandibular joint are located in the anterior recess and the retrodiscal tissue of the upper compartment.…”

“…Arthroscopic lysis and lavage has been an effective treatment for TMJ disorders refractory to nonsurgical treatments (Ohnuki et al, 2003;Sanroman, 2004;Politi et al, 2007). An evaluation following temporomandibular joint arthroscopic surgery with lysis and lavage after 2 to 10,8 years treatment showed that arthroscopic surgery of the temporomandibular joint is successful in the long term for patients in case of osteoarthritis and painful motion (Sorel & Piecuch, 2000). Assessment of symptoms reported by the patient as well as of objective signs noted on clinical examination confirms resolution of pain on movement and increased vertical opening.…”

“…An adherence of the disc to the fossa may be caused by an alteration of the normal lubrication of the joint as a result of intermittent joint overloading, with secondary activation of oxidative species and degradation of hyaluronic acid. Anchored Disc Phenomen could be one of the first clinical symptoms observed in the chain events that would end in a more severe internal derangement (Sorel & Piecuch, 2000;Krug et al 2004). …”

“…In other study (Leibur et al 2010) closed lock was found in 17,2 % and fibrillations in 75,8 % of cases. Several authors (K. Murakami et al, 2000;Sorel & Piecuch, 2000) performed long-term evaluation following temporomandibular joint arthroscopic surgery with lysis and lavage covering 10 years. On the bases of assessment of symptoms reported by the patients as well as objective signs noted on clinical examination confirmed resolution of pain on movement and increased maximal interincisial opening..…”

“…This course of events may explain the efficacy of lysis and lavage of only this joint space, as this manipulation allows translation of the disc along the eminence, allowing the condyle to complete its natural path. The data in the literature have stated that the most frequent disc displacements were anterior and anteromedial ( Sorel & Piecuch, 2000). In episodes of closed lock , the limitation in condylar movement probably originates from changes in the upper compartment that restrict the sliding motion of the disc.…”
