Abstract:
Disc displacement is a common disorder of the temporomandibular joint (TMJ) that often results in progressive joint dysfunction, including clicking, arthralgia, functional limitations, osteoarthritis, and even condylar resorption. Several arthroscopic techniques have been proposed to treat anterior disc displacement. Yang's arthroscopic disc repositioning and suturing technique, described in 2012, consist in a pair of sutures inserted through the junction of the disc and the retrodiscal tissue and tied underneath the cartilage of the external auditory canal. This technique is reported to be the most stable over time, but it has 2 main disadvantages, 1) it is one of the most challenging to perform, requiring a skill TMJ arthroscopic surgeon and 2) it needs a customized suture equipment. We designed a modification to Yang's technique using a common, cheap, available and disposable suture set.
