Minimally Invasive Treatment With Zygomatic Complex Fracture Reduction by Percutaneous Bone Hook Traction

Abstract

The purpose of this study was to evaluate the effectiveness of zygomatic complex fracture reduction by percutaneous bone hook traction as a minimally invasive treatment. A retrospective case series analysis of 24 patients who underwent unilateral isolated zygomatic complex fracture reduction by percutaneous bone hook traction between June 2014 and June 2019 was performed. Patients who complained of other accompanying maxillofacial fractures or ocular problems were excluded. Postoperative radiographs were used to assess the esthetic appearance and treatment response, including complications, in all patients. Operation was performed within a mean time of 5.3days after injury. Closed reduction by percutaneous bone hook traction was performed in 24 patients. At a regular follow-up period of 6months, postoperative radiographs showed symmetrical outcomes of facial contours and bony union without zygomatic collapse. All patients were satisfied with the symmetrical contours of the zygomatic complex and experienced no complications. Three of the 7 patients had paresthesia in the infraorbital region after injury and regressed postoperatively. Percutaneous bone hook traction could be an alternative treatment method for simple noncommunicated zygomatic complex fractures without preoperative ocular problems 7days after injury. Deep understanding of the operative indication, choosing a suitable operation time, and experienced surgeons are keys to effectively using this economical, reliable, and effective approach.
