Dislocation of the temporomandibular joint (TMJ) is the displacement of the head of the condyle from its normal position in the glenoid fossa. Anterior dislocations are the most common type of TMJ dislocations. Prognathism of the lower jaw, anterior crossbite, and open bite are the classic features in bilateral TMJ dislocations.The treatment of acute TMJ dislocation involves manual reduction with or without general anesthesia. The use of maxillomandibular fixation is reserved for chronic, more complex dislocations. Determining the presence of a predisposing factor is very important in guiding the correct treatment and management for this condition.The authors present a case of acute spontaneous temporomandibular joint dislocation where multiple predisposing factors were recognized, requiring treatment with maxillomandibular fixation after manual reduction.
颞下颌关节（TMJ）脱位是髁突头部从关节窝正常位置发生的移位。前脱位是颞下颌关节脱位最常见的类型。下颌前突、前牙反合和开牙合是双侧颞下颌关节脱位的典型特征。急性颞下颌关节脱位的治疗包括在有或没有全身麻醉的情况下进行手法复位。颌间固定用于慢性、更复杂的脱位。确定诱发因素的存在对于指导这种情况的正确治疗和管理非常重要。作者报告了一例急性自发性颞下颌关节脱位病例，该病例存在多种诱发因素，手法复位后需要颌间固定治疗。
