Superolateral dislocation is rarely encountered in clinical practice. It is usually associated with fracture of the contralateral mandibular body or zygoma. The occurance of type II superolateral dislocation of the condyle without associated fracture is very rare and only a few cases are reported in literature.
We present a case report in which the patient had a type II superolateral dislocation of the mandibular condyle which is not associated with any fracture. The condyle was hooked laterally above the zygomatic arch. The fracture was reduced surgically and good results were obtained.
We thereby would like to ascertain the fact that a type II superolateral dislocation of the mandibular condyle can occur without any associated fractures.
临床上很少遇到髁突外上脱位。它通常与对侧下颌骨体或颧骨骨折相关。不伴有骨折的Ⅱ型髁突外上脱位非常罕见,文献中仅报道了少数病例。
我们报告一例患者发生了不伴有任何骨折的下颌髁突Ⅱ型外上脱位。髁突钩挂在颧弓上方外侧。通过手术复位骨折,取得了良好效果。
我们借此确定了下颌髁突Ⅱ型外上脱位可在不伴有任何相关骨折的情况下发生这一事实。
