Background: Many procedures can be used to reposition the disc using arthroscopic approach, but they are technically complex and offer questionable results due to their fixation to soft tissues. A technique consisting of disc fixation to the mandibular condyle with a resorbable pin by an arthroscopic approach has been developed with good results. Objective: The aim of this paper is describe the findings in a bilateral arthroscopy two years later the placement of this pin. Methods: A 21-year-old female consulted for a two months lock, presenting temporomandibular joint (TMJ) disc anterior displacement without reduction in left side. A bilateral arthroscopy was performed in July 2011, when a resorbable pin was placed in the left TMJ. In March 2013 the patient presents a new luxation in the right side, so she went through a new arthroscopy in June 2014. In this procedure a new pin was located in the right condyle, and an exploration of the left side was performed. Findings: We could find a slight synovial inflammation, with a grade I synovitis, with a 100% roofing and disc remained in its normal position. We could not find the head of the pin previously placed as it is supposed that was completely resorbed. Conclusion: Arthroscopic implant of a resorbable pin appears an alternative to other treatments for anterior luxation of the TMJ disc with doubtful results. In the case we present we could verify in a direct way how the pin was complete reabsorbed and the disc kept the same position.
