Abstract：
UNASSIGNED: The article presents a rare case of acute malocclusion produced by a unilateral partial tear of the lateral pterygoid muscle and an up-to-date literature review of the pathology.
UNASSIGNED: A 37-year-old female was examined; her chief complaints were pain on the right side of the temporomandibular joint (TMJ) area and mastication impairment associated with major occlusal modifications and anterior open bite. After magnetic resonance imaging (MRI) and cone beam computed tomography (CBCT) of the TMJ and subsequent MRI for soft tissue, the final diagnosis was a partial right lateral pterygoid muscle tear.
UNASSIGNED: The case shows the value of combined imaging in temporomandibular disorders (TMD) and the importance of soft tissue evaluation in addition to articular examination, as the primary pathology might lie outside the joint. The authors\' review of the current literature did not hitherto reveal a similar case.

摘要：
■本文介绍了一例罕见的急性错牙合畸形病例，该病例是由翼外肌单侧部分撕裂引起的，并对其病理学进行了最新文献综述。
■检查了一名37岁的女性；她的主要主诉是颞下颌关节（TMJ）区域右侧的疼痛以及与主要咬合修改和前开放咬合相关的咀嚼障碍。在TMJ的磁共振成像（MRI）和锥形束计算机断层扫描（CBCT）以及随后的软组织MRI之后，最终诊断为部分右侧翼外肌撕裂。
■该病例显示了联合成像在颞下颌关节紊乱病（TMD）中的价值以及除关节检查外的软组织评估的重要性，因为主要病理可能位于关节外。作者对当前文献的回顾迄今没有发现类似的案例。
