Holmium:YAG laser arthroscopy of the temporomandibular joint.

A new pulsed midinfrared laser has become available for use in arthroscopic surgery of the temporomandibular joint (TMJ). This article reviews holmium:YAG (yttrium-aluminum-garnet) laser physics, its tissue effects, and reports initial experience with its use in TMJ arthroscopy. Because the Ho:YAG laser can precisely and rapidly resect cartilaginous tissues with only moderate necrosis, can function in a saline environment, and can be transmitted through conventional optical fibers, it has the potential of becoming a useful and adaptable system for TMJ arthroscopic surgery.
