This study reports a case of Jacob's disease characterized with limited mouth opening due to bilateral coronoid hyperplasia forming pseudojoints with zygomatic arches. Magnetic resonance (MR) examination of temporomandibular joint (TMJ) is usually the imaging method chosen in patients with such symptoms. However, the coronoid processes can not be displayed because they are not included in field of view in MR imaging of TMJ. For that reason, these patients may be treated for a misdiagnosis of TMJ disorders. In this study, the aetiology and diagnostic methods of Jacob's disease, the pre-operative/post-operative role of three-dimensional computed tomography and some measurements used in diagnosis were evaluated.
本研究报告了一例雅各布病病例，其特征为双侧喙突增生与颧弓形成假关节，导致张口受限。颞下颌关节（TMJ）的磁共振（MR）检查通常是有此类症状患者所选用的成像方法。然而，由于喙突未包含在TMJ的MR成像视野内，所以无法显示。因此，这些患者可能会被误诊为TMJ紊乱而接受治疗。在本研究中，对雅各布病的病因和诊断方法、三维计算机断层扫描在术前/术后的作用以及一些用于诊断的测量方法进行了评估。
