Long-standing temporomandibular joint (TMJ) dislocation is an uncommon condition, and due to its rarity, no definitive guidelines have been developed for its management. Various reduction techniques ranging from indirect traction techniques to direct exposure of the TMJ have been used. Indirect traction techniques for reduction may fail in long-standing dislocation. Management of two cases of long-standing TMJ dislocation with midline mandibulotomy is discussed in which other indirect reduction techniques had failed. Midline osteotomy of the mandible can be used for reduction in difficult TMJ dislocations. An algorithm for the management of long-standing TMJ dislocation is proposed and related literature is reviewed.
长期颞下颌关节（TMJ）脱位是一种罕见的病症，由于其罕见性，尚未制定出明确的治疗指南。从间接牵引技术到TMJ直接暴露的各种复位技术都曾被使用过。间接牵引复位技术在长期脱位中可能会失败。本文讨论了两例采用下颌骨中线切开术治疗长期TMJ脱位的病例，此前其他间接复位技术均告失败。下颌骨中线截骨术可用于治疗困难的TMJ脱位。本文提出了一种长期TMJ脱位的治疗方案，并对相关文献进行了综述。
