Abstract 【Objective】To compare the clinical effects between external fixation and endoscopic open reduction with internal fixation in the treatment of zygomatic arch fractures. 【Methods】The clinical data of 80 patients with zygomatic arch fractures who underwent external fixation (control group,n=40) and endoscopic open reduction with internal fixation (study group,n=40) in our hospital between June 2011 and April 2013 were analyzed retrospectively. All subjects were followed up for 3 years. The one-stage healing rate of incision, incidence of postoperative complications and prognosis of the patients (incidence of residual scar, excellent and good rate of occlusion, complete reduction rate of fractures) were compared. The differences in mouth-opening degree before and after operation were recorded. 【Results】After operation, the incision of both groups showed one-stage healing and there were no cases of facial paralysis, head and face skin numbness, limited chewing function, facial depression or other complications (P>0.05). There was 1 case of mild hair loss and 1 case of slight swelling of the face in study group after operation, and the symptoms spontaneously remitted. In the control group, there was 1 case with mild restriction of mouth-opening, and after 1 ~ 2 months of mouth-opening function training, it returned to normal. At 3 years after operation, the mouth-opening degree of both groups was significantly higher than that of before operation (P<0.05), but there was no significant difference between the two groups (P>0.05). At the last follow-up, there was presence of facial symmetry and the CT review showed good healing of zygomatic arch fractures, without residual scarring. The effective rate of occlusion and complete reduction rate of fractures was 100% (P>0.05). The occluding relation was basically the same as before injury. 【Conclusion】Both external fixation and endoscopic open reduction with internal fixation are of high application value in the clinical treatment of patients with zygomatic arch fractures. Patients can choose the optimal operation according to the actual situation to create conditions for improving the recovery effect of prognosis.
