"Diagnostic and Therapeutic Effect of Endoscopically Assisted Arthrocentesis to Improve the Mobility of the Mandible in Internal Temporomandibular Joint Disorders"

Abstract

Objective: To compare the diagnostic and therapeutic effect of endoscopically assisted arthrocentesis with conventional arthrocentesis and arthroscopy.Material and Methods: 372 TMK examinations and treatments were performed from January 2019 to April 2021 (27 months). We monitored the pain level on the VAS scale, the extent of interincisal distance, and the value of NMR scans before and after treatment.Results: By comparing the results of clinical examination, graphical imaging and statistic evaluation of conventional arthrocentesis under local anesthesia, conventional arthroscopy under general anesthesia, and innovative endoscopic-assisted single cannula three-way arthrocentesis under local anesthesia, it can be seen that the postoperative interincisional distance and grade values for pain after surgery are better for surgical procedures under local anesthesia with the innovative endoscopicassisted single cannula three-way technique. Particularly significant are the improved values for the larger range of interincisional distance. Conclusion:By assessing the intraarticular structures based on NMR examinations and the Wilkes classification scheme, we found that all minimally invasive procedures resulted in improved pathologies. Based on clinical experience, we can conclude that the innovative endoscopically assisted single cannula three-way arthrocentesis under local Anaesthesia is superior to conventional arthroscopy under general Anaesthesia and conventional arthrocentesis under local Anaesthesia.
