Comparison of the Clinical Efectiveness of Intra Articular Injection With Diferent Substances After TMJ Arthroscopy: a Systematic Review and MetaAnalysis
Objectives: This systematic review aims to describe the clinical outcomes after TMJ arthroscopy followed by intra articular infiltration with different substances. Methods: A literature search was carried out, the variables were Arthroscopy with different substances, pain and maximal mouth opening. The inclusion criteria were articles that reported infiltration of different substances after arthroscopy. Case series, observational studies, and randomized clinical trials were included. Exclusion criteria were studies that included arthrocentesis, animal studies, connective tissue disease, patients with previous surgeries. Results: Of the 5 studies finally included, the population studied were 346 subjects, of which 315 were female. The mean age was 34.7 (16–77). Regarding diagnoses, Wilkes III and Wilkes IV were taken into account. The most commonly used substance was sodium hyaluronate/hyaluronic acid in 4 of the 5 studies. Conclusions: Multiple substances have been infiltrated within the temporomandibular joint, with sodium hyaluronate/hyaluronic acid being the most studied. However, the benefit of substances like TMJ arthroscopic adjuvants has not been clearly established. It is recommended in future studies that the substances and results be evaluated in the same way to obtain more homogeneous studies.
