目的:探讨影响下颌角骨折术后恢复的相关因素。方法:收集2007年1月至2015年6月因下颌角骨折就诊于新疆医科大学第一附属医院颌面外科行手术治疗的患者资料,按术后的恢复情况分为愈合良好、愈合欠佳两组。并对可能影响下颌角骨折术后愈合的相关因素进行单因素及多因素Logistic回归分析。结果:单因素分析结果显示:第三磨牙的处理、颌间牵引、吸烟和固定物数量是影响下颌角骨折术后愈合的因素,多因素回归分析得出:吸烟(OR=5.660 95%CI:1.182~27.106)、固定物数量(OR=0.189 95%CI:0.044~0.816)与下颌角骨折术后恢复密切相关。结论:两块固定物即张力带联合下颌下缘固定有利于下颌角骨折术后愈合,吸烟是影响下颌角骨折愈合的危险因素,医护人员应尽早了解相关因素,并采取有效措施促进下颌角骨折的愈合。
Objective: To explore the factors that affect the recovery of mandibular angle fractures. Methods: The data of patients undergoing maxillofacial surgery in Department of Maxillofacial Surgery, the First Affiliated Hospital of Xinjiang Medical University from January 2007 to June 2015 were retrospectively analyzed. According to the postoperative recovery, they were divided into two groups: good healing and poor healing group. Single factor and multivariate logistic regression analysis were performed on the related factors that may affect the healing of mandibular angle fractures. Results: The results of univariate analysis showed that the treatment of third molars, intermaxillary traction, smoking and the number of fixatives were the factors affecting the healing of mandibular angle fractures. Multiple regression analysis showed that smoking (OR = 5.660 95% CI: 1.182 ~ 27.106). The number of fixators (OR = 0.189 95% CI: 0.044-0.816) was closely related to the recovery of mandibular angle fractures. Conclusion: The fixation of two fixation devices, tension band and lower mandibular edge, is beneficial to the healing of mandibular angle fractures. Smoking is a risk factor for the healing of mandibular angle fractures. The medical staff should understand the relevant factors as soon as possible and take effective measures to promote the mandibular angle fractures Healing.
