RESUMEN
<p><b>OBJECTIVE</b>This study aimed to compare the treatment effects of simultaneous surgical treatment and stage operation for patients with craniomaxillofacial fracture combined with other injuries.</p><p><b>METHODS</b>Fifty patients with maxillofacial fractures combined with other injuries were chosen and divided into simultaneous (28 patients) and staging (22 patients) operation groups. In simultaneous operation group, maxillofacial fracture reduction, internal fixation, and other parts of the surgery were simultaneously operated by relevant departments jointly. In the staging operation group, maxillofacial fracture reduction and internal fixation were performed after treatment of other injuries. Data on the treatment efficacy and associated injuries of the two groups were statistically analyzed.</p><p><b>RESULTS</b>In the simultaneous operation group, 26 patients had good occluding relation, the maximum mouth opening was (34.5 +/- 3.7) mm, the symmetry and shape of hard tissues recovered well, and the bone plate of one patient was removed because of internal fixation infection. In the staging operation group, 14 patients had good occluding relation, the maximum mouth opening was (28.5 +/- 3.5) mm, the symmetry and shape of hard tissues poorly recovered, and the bone plates of 5 patients were removed because of internal fixation infection. Statistical significance was determined among occluding relation, maximum mouth opening, postoperative complications, and length of stay of the two groups (P< 0.05). Treatment of the simultaneous operation group was more effective than that of the staging operation group.</p><p><b>CONCLUSION</b>When a patient's condition is relatively stable, simultaneous surgical treatment of multiple specialties should be conducted to treat craniomaxillofacial fracture combined with other injuries.</p>
