[Value of magnetic resonance imaging for diagnosis of temporomandibular joint dysfunction].

Background: Temporomandibular joint affection is a frequent problem in the adult population, the most common form being a series of functional alterations known as temporomandibular joint dysfunction. Magnetic resonance imaging has emerged as the most appropriate test in the assessment of the joint, primarily as a non-invasive test that allows the acquisition of images in different planes.

Objective: The study aims to reaffirm the usefulness of magnetic resonance imaging study in the evaluation of the temporomandibular joints and to demonstrate differences in age and sex of more frequently associated alterations and side effects.

Methods: A prospective, observational, descriptive study in which we evaluated the presence of joint dislocations and degenerative bone changes, degeneration and/or disc perforation and inflammatory disorders.

Results: In 35 patients studied, all of whom had some symptoms of joint dysfunction, with ages ranging between 37 and 65 years, and with an average of 52 years, eight were normal, in 26 patients we found associated alterations with joint dysfunction, and in 14 patients the affected side was the right and the left in 10 patients.

Conclusion: MRI should be the study of choice for a patient with temporomandibular dysfunction symptoms, as it has demonstrated excellent visualization of the joint in different acquisition planes.
