Internal derangement (ID) of the temporomandibular joint (TMJ) managed by arthrocentesis is considered a minimally invasive technique with limited indications and unpredictable outcomes in advanced cases. On the other hand, for predictable, long-standing, and trustworthy results, arthroscopy is important in the management of TMJ disorders due to it minimum invasiveness and morbidity. The learning curve in TMJ arthroscopy is steep for new surgeons, requiring extensive teaching and training¹. The role of the surgical assistant is equally important in TMJ surgery for successful TMJ mobilization and adherence to safety procedures to avoid postoperative complications¹. McCain improved hard and soft devices for TMJ arthroscopy using a ‘coblation’ high-frequency wave system for tissue cutting and debridement². Additional studies must produce innovations in various concepts of TMJ surgeries. Compared with arthrocentesis, arthroscopy leads to greater melioration in the maximum interincisal opening after 12 months, with no difference in pain reduction³. An evidence-based study showed reduction in TMJ pain after 12 months with no difference in outcomes such as mandibular functionality³. Arthroscopy can be a useful technique for treatment of patients with advanced stages of ID of the TMJ in all age groups. However, longer follow up was suggested⁴.

Corroboration-based management for patients with TMJ disorders must be verified by evidence-based scientific research.
