按照 "dislocation of orbital bones" 查询未有结果，Goole 显示均为 "orbital fracture" 或者 "orbital floor fracture" or "broken orbital bone(s)". 如果是儿童，是否为 trapdoor fracture, "Trapdoor fractures generally only occur in children because their bones are more flexible. They are a type of orbital floor fracture. Instead of fracturing, the bones flex outward, then return to their normal position."
