  • Title: Internal derangements of the temporomandibular joint: the role of arthroscopic surgery and arthrocentesis.
    Author: Barkin S, Weinberg S.
    Journal: J Can Dent Assoc; 2000 Apr; 66(4):199-203. PubMed ID: 10789172.
    Abstract:
    Arthroscopic surgery appears to be a safe, minimally invasive and effective method for treating internal derangements of the temporomandibular joint (TMJ), reducing pain and increasing mandibular range of motion for approximately 80% of patients. Although these results are encouraging, they are largely based on retrospective, uncontrolled and short-term studies. The landmark observation that lysis and lavage in only the upper compartment of the TMJ produce successful clinical results without repositioning the disc has prompted clinicians to question the importance of disc position as a significant factor in the etiology of TMJ pain dysfunction. Although there are prospective, controlled, randomized short-term studies indicating that arthrocentesis and arthroscopic surgery have comparable success rates in the management of acute TMJ closed lock, similar long-term studies are lacking. Until they have been done, the roles of arthroscopic surgery and arthrocentesis in the management of TMJ internal derangements remain unclear.
