ABSTRACT
The Temporomandibular Joint Dysfunction Syndrome (TJDS) is a group of pathologies that affect the temporomandibular joint, mastication muscles, and attached structures, 1 of the leading causes of orofacial pain. Arthroscopy is a technique used as a method of treatment for TJSD. This was a retrospective cohort study, and data were collected from the medical records of patients with TJDS. The diagnosis of TJDS was established based on computed tomography and nuclear magnetic resonance imaging tests, and clinical examination. All patients, who underwent arthroscopy, were operated on by the same surgeon in 2020. The variables analyzed in this study were: maximum mouth opening, laterality, and protrusion of patients undergoing arthroscopy at time intervals of 30, 90 days, and 6 months after surgery. Data from anamnesis of the medical records and findings on clinical examination were used to verify whether there was any correlation with good postoperative evolution. Afterward, these data were compared and submitted to statistical analysis (Wilcoxon (nonparametric and paired) and Mann-Whitney (nonparametric, unpaired) tests) to verify the degree of correlation between them. It could be concluded that in this sample, arthroscopy reduced the degree of pain in patients, increased mouth opening amplitude, and did not influence laterality and protrusion. The use of previous medication was correlated with a slight decrease in postoperative pain; patients who had undergone previous orthodontic treatment showed better results regarding maximum mouth opening without pain; patients who had previously felt pain on professional palpation had greater maximum mouth opening with and without pain after arthroscopy, and patients with noise at professional auscultation had greater maximum mouth opening without pain. Further studies should be conducted, with larger samples, associated with complementary exams (computed tomography and nuclear magnetic resonance) before and after arthroscopy.
