Innovative technique for inferior compartment arthroscopy of the temporomandibular joint: a safe and reproducible approach.

Visualization of the inferior joint space of the temporomandibular joint (TMJ) by arthroscopy is still a challenge for many surgeons, because there are no standard references for how to approach it. This study describes the steps for performing a TMJ arthroscopy technique in the inferior joint space, using anatomical and numerical references. It consists of three steps: marking the reference points, entering the inferior joint space with the cannula, and inserting a needle for continuous Ringer solution irrigation. The precision of this new technique allows greater reproducibility and safety in clinical application.
