Single-channel thin-fiber and Nd:YAG laser temporomandibular joint arthroscope: development and preliminary clinical findings.

This study evaluated the development and preliminary results of a single-channel thin-fiber and Nd:YAG laser temporomandibular joint arthroscope. No articular damage from the arthroscopic procedure and laser lysis was observed in any of the joints when the arthrotomy was performed. All three disk perforations found by the arthroscope were confirmed at the time of the arthrotomy, and in these joints the tip of the arthroscope could be advanced into the inferior joint. The nine joints, where only arthroscopic laser lysis was performed, were followed up and the results were satisfactory.
