摘要：Introduction: Literature discussing the use of rigid external distraction devices in midfacial trauma is limited. Rigid external distraction devices have been described for use in craniofacial surgery, allowing for distraction and stabilization of bony segments. In complex facial trauma, bony fragments are often comminuted and unstable, making traditional approaches with internal fixation difficult. Moreover, these approaches require subperiosteal dissection, limiting blood supply that is important for bone healing. Objective: The goal of this study was to evaluate the role of rigid external distraction devices for the treatment of complex facial trauma. Methods: We performed a literature review of rigid external distraction devices, as relevant both for facial trauma and for other craniofacial indications, to better elucidate their use and efficacy in complex facial fractures. Results: The review revealed only 2 articles explicitly describing rigid external distraction devices for facial trauma, while 6 other articles describing its use for other craniofacial cases. An important benefit associated with the use of rigid external distraction devices is their ability to provide controlled traction of bony segments while also allowing for movement as needed for fracture reduction. Various articles describe performing internal fixation following rigid external distraction device usage, while others emphasize that internal fixation is not necessarily indicated if the rigid external distraction device is left intact long enough to ensure bony healing. One potential setback described is unfamiliarity with using the rigid external distraction device, which can preclude its use by many surgeons. In addition, the literature review did not provide any uniform guidelines or recommendations about how long rigid external distraction devices should remain intact. Conclusion: Based on relevant literature, rigid external distraction devices have been shown to be useful in the stabilization and treatment of complex facial fractures. Further studies should be conducted to better elucidate the specific indications for rigid external distraction devices in complex facial trauma.
