摘要
Hypermobility of a temporomandibular joint (TMJ) is usually a result of mouth opening beyond normal limits of translational movement of discus-condyle complex. It can lead to condyle dislocation over the top of the articular eminence of temporal bone.
We present the case of posttraumatic bilateral hypermobility of the TMJ and the role of magnetic resonance imaging (MRI) in diagnostic algorhytm.
MRI is a crucial tool in the diagnostics of temporomandibular dysfunctions (TMD) because it has capability to show TMJ discus without using ionizing radiation. In diagnostic algorhytm MRI uses no i.v. administration of contrast material and therefore presents non invasive method.
