摘　　要：目的　调查下齿槽神经损伤在下颌骨骨折中的发生情况 ,分析可能的影响因素 ,为下颌骨骨折神经损伤早期诊断 ,早期治疗及对预后正确评估提供依据。方法　对 30例患者 31处骨折情况进行调查随访 ,分析患者一般情况、骨折治疗方法、骨折移位、骨折类型及患侧下齿槽神经分布区的感觉功能检查等因素与下齿槽神经感觉异常之间的关系。结果　下齿槽神经损伤的发生率与患者年龄 (相关系数 =- 0 .15 5 4 )、术前骨折移位 (相关系数 =- 0 .4 94 8)及坚强内固定治疗 (相关系数 =- 1.9888)有关。结论　年龄大 ,下颌骨骨折移位严重和使用坚强内固定治疗 ,下齿槽神经损伤发生的可能性大、严重程度高。Objective To find out the factors influencing the injury of the inferior alveolar nerve associated with mandibular fractures,thereby helping the surgeon diagnose and deal with the nerve injury as early as possible.Methods Sensory status of the inferior alveolar nerve was monitored in 30 patients with 31 fractured sites of the mandibles. The following variables were studied in each patient: age, sex, type of fracture, time span between fracture occurrence and treatment, degree of displacement,and type of treatment.Results Preoperatively, the sensory abnormalities were related to the age (B=-0.1554) of patients and the fracture displacement (B=-0.4948); postoperatively, the related factor was treatment with rigid internal fixation (B =-1.9888).Conclusion The sensory abnormalities of the inferior alveolar nerve after mandibular fracture are related to the age of patients,the degree of segment displacement,and treatment method.
