Modified method of TMJ arthrocentesis with synchronous feeding with two needles under ultrasound control

Abstract

The aim of the study was to develop and apply a modified technique of 2-puncture arthrocentesis of the upper TMJ joint space with simultaneous supply of saline solution for the treatment of patients with anterior disc displacement. Based on literature data and our own research, a modified method of TMJ arthrocentesis with synchronous solution feeding by two needles under ultrasound control under local anesthesia was proposed. The application of the proposed method for the treatment of a 31-year-old patient with internal TMJ disorders with complaints of clicks and periodic pain in the right TMJ area is described. The use of a modified arthrocentesis technique showed an increase in the maximum mouth opening immediately after the procedure by 0.2 cm (from 4.2 to 4.4 cm) and a decrease in clicks in the right TMJ during mandibular movements. The time spent on the procedure was less than 2 minutes, while saline was injected in a volume of up to 2 mlt is concluded that the modifie d method of TMJ arthrocentesis with synchronous injection of the solution with two needles is effective and promising, allowing to reduce the volume of the solution and the time spent on the procedure compared with the classical methods of arthrocentesis and arthroplavage, and the ultrasound guidance used allows you to control the correct position of the needles and the distribution of the wound in the joint gap. At the same time, further clinical studies with control groups and a larger sample of patients are needed for wider application of the method.
