Arthroscopic removal of nodules of synovial chondromatosis of the temporomandibular joint.

In this report we describe a new method for removing nodules of TMJ synovial chondromatosis using arthroscopic surgery instead of open surgery. We used two steps during arthroscopy. In the first, we lavaged the cavity with sterile saline. In the next step, the second cannula was replaced with ethmoid forceps. Under arthroscopic guidance through the first cannula, all loose bodies were removed using the forceps. Since the loose bodies are not fragmented during this procedure, the time needed for removal is shortened. Based on this experience, we suggest the use of ethmoid forceps should be considered as an alternative procedure when nodules are unable to pass through the cannula by lavage with sterile saline.
