Temporomandibular joint arthroscopy by inferolateral approach.

A clinically successful technique for temporomandibular joint (TMJ) arthroscopy by the inferolateral approach is reported. The outline of the superior and inferior articular cavities of the TMJ except for the lower anterior pouch could be visualised; arthroscopy could be performed on most patients under local anesthesia in the out-patient operating room. Clinical usefulness and security of the TMJ arthroscopy based upon anatomical understanding is described.
