ハロー型骨延長器を用いた中顔面骨折症例の治療経験

抄録

  In midfacial fractures caused by a traffic accident or fall, the face is impacted by a strong external force that causes damage to soft tissues and bone structures. Moreover, complications are often caused due to the involvement of proximal intracranial, orbital, and paranasal sinuses. To treat midfacial fractures, reduction of facial structures and fixation of facial bones are performed with buttresses or reference points that support the facial structures. However, in patients with midfacial fractures, buttresses and reference points are lost, which poses surgical difficulties. In the present case, we conducted elective cricothyrotomy only during surgery for midfacial fractures and fixation using a halo-type bone extender (BLUE DEVICE^TM, Zimmer Biomet, USA). The postoperative course was favorable and good functional and esthetic outcomes were obtained. Four years after the removal of the halo-type bone extender, the outcome continued to be favorable.
