Abstract:
Disc perforation represents the result of the degenerative process in joint structures that may lead to pain, joint noise, restricted mouth opening, osteoarthritis, and even dentofacial anomalies. Even though discectomy has proven benefits, with promising outcomes reported, it is mainly described using an open approach. While some arthroscopic techniques have been published, they are limited to managing perforation, edge widening, and inflammation treatment and do not describe complete disc removal. We describe a novel step-by-step arthroscopic discectomy technique utilizing two operative cannulas that completely remove nonfunctional cartilaginous tissue.
