Temporomandibular joint (TMJ) dislocation is a common occurrence, but diagnosis can be missed if patients do not complain. Delayed presentation complicates the management of a straightforward reduction. We present a case of a 24-year-old man who had bilateral TMJ dislocation of unknown duration after motor vehicle accident. The accident left him bedridden with speech difficulty. He was totally dependent on Ryles' and percutaneous endoscopic gastrotomy tubes for feeding. Computed tomography revealed dislocation of condyles anterior to articular eminences. The bilateral TMJ dislocations were reduced surgically via bicoronal with preauricular extension approaches. However, the surgery was challenging due to tissue changes around the joint accompanied by masticatory muscles atrophy. Postoperatively, he was placed on intermaxillary fixation for 2 weeks followed by elastics training. Three months later, the patient's mastication returned completely to function. Delayed management of bilateral TMJ dislocation is undoubtedly challenging and somewhat frustrating; nevertheless, we manage to achieve satisfactory outcome in improving the patient's quality of life.
颞下颌关节(TMJ)脱位很常见,但如果患者没有主诉,可能会漏诊。延迟就诊会使简单复位的处理变得复杂。我们报告一例24岁男性,在机动车事故后出现双侧颞下颌关节脱位,脱位持续时间不明。事故导致他卧床不起且言语困难。他完全依赖鼻胃管和经皮内镜下胃造瘘管进食。计算机断层扫描显示髁突位于关节结节前方脱位。通过双冠状切口加耳前延伸入路对双侧颞下颌关节脱位进行了手术复位。然而,由于关节周围组织改变并伴有咀嚼肌萎缩,手术具有挑战性。术后,他接受了2周的颌间固定,随后进行弹性训练。三个月后,患者的咀嚼功能完全恢复。双侧颞下颌关节脱位的延迟处理无疑具有挑战性且有些令人沮丧;尽管如此,我们仍设法在改善患者生活质量方面取得了满意的结果。
