摘要
下颌骨髁突颈部结构薄弱,受外力作用时容易折断,从而通过缓冲创伤能量,避免颅中窝及颅脑等重要解剖部位受到损伤,可视为人体的一种自我保护机制。本文报告1例较为少见的髁突颅内移位外伤病例,髁突在未发生骨折的情况下向上移位,突破颅中窝底进入颅内,并结合相关文献,就其发生机制、临床表现、诊断及治疗进行讨论。
The structurally weak mandibular condylar neck is more likely to break when subjected to external force.Mandibular condyle fractures can dissipate the traumatic energy, avoiding damage to the middle cranial fossa and other important anatomical structures of the brain, which can be regarded as a self-protection mechanism of the human body. A rare case of traumatic dislocation of the mandibular condyle into the middle cranial fossa was reported in this paper. The patient’s mandibular condyle without fracture was dislocated through the base of the middle cranial fossa into the cranium.The pathogenesis, clinical manifestations, diagnosis and treatment for intracranial dislocation of mandibular condyle were discussed with review of relative literatures.
