目的探讨下颌骨骨折不同手术时机与术后并发症的关系。方法回顾2007—2012年济南市第五人民医院口腔科收治的下颌骨骨折患者61例,按伤后手术时机的不同将患者依次分类,观察各患者术后感染、骨折畸形愈合和骨折不愈合的发生情况,数据采用Logistical回归分析和方差分析。结果 61例患者中有5例出现术后并发症,无骨折不愈合病例。Logistical回归分析得知延迟手术对全部并发症的相对危险度为0.61(P=0.12),对感染的相对危险度为0.82(P=0.39),对骨折畸形愈合的相对危险度为0.61(P=0.12);各组并发症发生与否的手术时机差异无统计学意义(P>0.05)。结论下颌骨骨折的手术时机与术后并发症的发生无明显关联。
Objective To investigate the relationship between different operation timing and postoperative complications in mandibular fracture. Methods A retrospective review of 61 cases of mandibular fractures admitted to Department of Stomatology, the Fifth People’s Hospital of Ji’nan City from 2007 to 2012 was conducted. The patients were classified according to the timing of the operation and the postoperative infection, fracture malunion and nonunion The occurrence of the situation, the data using Logistical regression analysis and analysis of variance. Results Of the 61 patients, 5 cases had postoperative complications without fracture or nonunion. Logistic regression analysis showed that the relative risk of delayed surgery for all complications was 0.61 (P = 0.12), the relative risk for infection was 0.82 (P = 0.39), and the relative risk for fracture malunion was 0.61 (P = 0.12). There was no significant difference in the timing of operation between the two groups (P> 0.05). Conclusion There is no significant correlation between the operation timing of mandibular fracture and the incidence of postoperative complications.
