A comparative study of the clinical effects of simultaneous and delayed surgery for the treatment of cranial and maxillofacial fractures with multiple systemic injuries

Objective To investigate the clinical effect of simultaneous and delayed surgery with cranial and maxil⁃ lofacial fractures with multiple systemic injuries. Methods From January 2013 to January 2015, 85 cases of patients with multiple systematic injuries and maxillofacial fractures were treated in our hospital. Fractures of the maxillofacial parts and other parts of body were divided into 2 groups, 37 cases of delayed surgery, 48 of simultaneous surgery. The degree of neurologic impairment, occlusion, mouth opening, the time in hospital, postoperative complication rate were compared between two groups. Results There was no significant difference in the prognosis of the patients on the item of Glasgow outcome scale (GOS) in the simultaneous group and the delay group at 3 months after the operation (Z = ⁃1.545, P = 0.122). The excellent occlusion rate of simultaneous group (93.75%) was significantly higher than the delayed group (75.68%) (c2 = 5.630, P = 0.018). The mouth opening of simultaneous group (34.5 ± 3
