Abstract

IntroductionDiscopexy using resorbable pins is an arthroscopic technique to treat internal derangement of the TMJ, restoring the normal relationship between disc, condyle, and temporal bone. The objective of our study was to assess the 5-year clinical outcome of a series of patients treated with this technique. MethodsA study was conducted on a series of patients who underwent arthroscopic discopexy using resorbable pins between January 2007 and February 2018. All the patients were refractory to conservative treatment and classified as Wilkes stage III. Clinical data were recorded at 1-year, 3-year, and 5-year visits. Pre- and postoperative evaluation parameters were: joint pain (VAS scale), mandibular movements (mm), and articular locking and clicking. ResultsThe study included 33 patients and the technique was performed in 38 joints. Mouth opening increased significantly with each visit after surgery compared with preoperative scores (mean value of 10.65 mm, p < 0.001), with the mean value increasing significantly at the 5-year visit in relation to the mean value obtained at the 3-year visit. Patients reported significant decreases in pain after surgery, obtaining VAS values of under 10 at the 5-year visit (mean improvement of 56.95 points, p < 0.001). ConclusionsDiscopexy using resorbable pins resulted in a good and stable clinical outcome at the long-term follow-up.
