Abstract:
Objective To investigate the application of MRI in evaluation of the traumatic temporomandibular joint (TMJ) injury induced by type Ⅵ condylar fracture. MethodsMRI was performed in TMJs in 18 patients with type Ⅵ condylar fractures at days 3-14 post-injury and the MRI findings were analyzed. ResultsMRI findings of 18 patients with traumatic TMJ injury with 19 sides of type Ⅵ condylar fractures showed 15 sides of TMJ disk displacement,nine sides of capsule tear,16 sides of retrodiscal tissue tear (double-plate area) and 19 sides of joint effusion change. Conclusions MRI is very important in the diagnosis and evaluation of traumatic TMJ injury,since it can clearly display the TMJ injuries in type Ⅵ condylar fractures.Therefore,the clinical application of MRI is beneficial for selection of the therapeutic schedules.
