Value of magnetic resonance tomography in the evaluation of the efficiency of conservative treatment of various types ventral dislocation of the intraarticular disk temporomandibular joint

Abstract

Background. Magnetic resonance imaging (MRI) is a highly informative method for the diagnosis of various types of temporomandibular joint dysfunction (TMJ), which makes its use an integral component in choosing a treatment algorithm and evaluating its effectiveness.Objective. Determine the value of MRI in the diagnosis, planning and effectiveness of conservative treatment of patients with various types of ventral dislocation of the intra-articular disk TMJ.Design and methods. We analyzed the results of clinical and instrumental studies at the stages of planning, treatment and evaluating the effectiveness of conservative therapy in dynamics in 62 patients with complaints of pain in the joint area, difficulty opening the mouth and joint noise. Results. In patients from the dynamic observation group with complete ventral dislocation of the disc identified prior to treatment, conservative treatment underwent positive dynamics of clinical manifestations and the absence or negative dynamics of MRI results. In patients with partial ventral dislocation of the disk, there was a positive dynamic of both clinical manifestations and MR images after conservative treatment.Conclusion. MRI is a fundamental method in the complex diagnosis of various types of ventral dislocation of the disk, the use of which in certain cases allows us to predict the ineffectiveness of conservative therapy and becomes a decisive factor in the appointment of invasive treatment methods.
