简要总结
Compare the accuracy of ultrasonography and magnetic resonance imaging in the diagnosis of temporomandibular joint internal derangements.
详细描述
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.
