Brief Summary:
Compare the accuracy of ultrasonography and magnetic resonance imaging in the diagnosis of temporomandibular joint internal derangements.
Detailed Description:
Temporomandibular disorders (TMDs) are conditions that affect the temporomandibular joint (TMJ), often leading to pain and dysfunction. The most common cause of TMJ problems is internal derangements.
The term "internal derangements" refers to conditions with the articular disc displaced from its original position on the mandibular condyle.
Disc displacement may occur anteriorly, anterolaterally, laterally, anteromedially, medially, or posteriorly, but the latter is very rare.
Anterior disc displacement (ADD) is the most common ID condition and is usually divided into two categories: with reduction and without reduction. Each category has special features during closed and opened mouth positions. Therefore, the examination should include both positions.
Clinical examination alone isn't enough to diagnose TMJ problems, therefore additional imaging tests are often needed.
Magnetic resonance imaging (MRI) is the gold standard modality, however because of its limited availability, long scan time, and high cost, it is difficult to use MRI as a screening technique.
Ultrasound (US) has been recommended as an alternate diagnostic imaging modality for TMJ problems as it is less costly, non-invasive and capable of providing real-time imaging, presents an alternative diagnostic tool. Thus, the articular disc may be seen as the patient is opening and closing their mouth
