Dislocation of the mandibular condyle into the middle cranial fossa is a rare complication of mandibular trauma due to anatomical and biomechanical factors. Owing to the proximity of the temporal glenoid fossa to the middle meningeal artery, there is the risk of serious sequelae in case of trauma. The authors report the case of a 36-year-old male patient, who was beaten up in a family dispute and presented with complex mandibular and maxillofacial fractures, including mandibular condyle intrusion into the middle cranial fossa causing extensive meningeal bleeding. The patient underwent immediate surgery, with evacuation of the epidural haematoma via a temporal approach. In addition open reduction and reconstruction of the temporal glenoid fossa via anatomic reduction of the fragments was performed. A functional occlusion was re-established via miniplate reconstruction of the complex mandibular body and ramus fractures. Prompt diagnosis and a multidisciplinary approach are essential to minimize the complications. Advanced imaging modalities of computed tomography are indicated. Treatment options should be individualized in particular in case of suspected neurological injury.
髁突脱位于颅中窝是由于解剖和生物力学因素导致下颌骨创伤的罕见并发症。由于颞下窝靠近脑膜中动脉,因此在创伤的情况下存在严重后遗症的风险。作者报告了一例 36 岁男性患者的病例,该患者在家庭纠纷中被殴打,表现为复杂的下颌骨和颌面骨折,包括髁突侵入颅中窝导致广泛的硬脑膜出血。患者立即接受了手术,通过颞部入路清除硬膜外血肿。此外,还通过解剖复位骨折碎片进行了颞下窝开放性复位和重建。通过复杂下颌体和支骨折的微型板重建恢复了功能咬合。及时诊断和多学科方法对于将并发症降至最低至关重要。应使用计算机断层扫描等先进的成像方式。在疑似神经损伤的情况下,应根据具体情况选择治疗方案。
