摘　　要：目的:探究颌骨骨折咀嚼效能恢复与不同内固定材料固定方式及预后的相关性。方法:选取2020年1月-2021年7月韶关市粤北人民医院收治的98例颌骨骨折患者,以随机数字表法将患者分为观察组(n=49)和参照组(n=49)。参照组以微型钛板及螺钉行坚强内固定术治疗,观察组以聚左旋乳酸(PLLA)可吸收内固定系统的坚强内固定术治疗。比较两组术前及术后3个月咀嚼效能指标(咀嚼效率、咬合力);比较两组骨折愈合时间、疗效、并发症发生情况;采用Pearson分析术后3个月咀嚼效能指标与骨折愈合时间的相关性;采用Spearman分析咀嚼效能指标与疗效的相关性;采用点二列相关分析咀嚼效能指标与内固定材料固定方式的相关性。结果:术后3个月观察组咀嚼效率、咬合力水平均高于参照组(P<0.05)。观察组骨折愈合时间短于参照组,观察组有效率为93.88%,高于参照组的73.47%(P<0.05)。观察组并发症发生率为10.20%,低于参照组的28.57%(P<0.05)。术后3个月咀嚼效能指标与内固定材料固定方式、疗效均呈正相关,咀嚼效能指标骨折愈合时间均呈负相关(P<0.05)。结论:颌骨骨折经PLLA可吸收内固定系统的坚强内固定术治疗后康复效果佳,使用PLLA可吸收内固定系统后咀嚼效能与预后指标改善明显,在极大程度上避免并发症的发生,因而临床治疗颌骨骨折时可优先考虑PLLA可吸收内固定系统。Objective:To explore the correlation between the masticatory efficacy recovery of jaw fractures and the fixation methods with different internal fixation materials and prognosis.Method:A total of 98 patients with jaw fracture admitted to Yuebei People's Hospital of Shaoguan from January 2020 to July 2021 were selected,they were divided into observation group(n=49)and reference group(n=49)by random number table method.The reference group was treated with rigid internal fixation with micro titanium plate and screw,and the observation group was treated with rigid internal fixation with poly-L-lactic acid(PLLA)absorbable internal fixation system.The indexes of masticatory efficacy(masticatory efficiency and bite force)before and 3 months after surgery were compared between the two groups;the healing time,curative effect and complications were compared between the two groups;Pearson was used to analyze the correlation between masticatory efficiency indexes and fracture healing time 3 months after surgery;Spearman was used to analyze the correlation between masticatory efficacy index and therapeutic effect;point-biserail correlation was used to analyze the correlation between masticatory efficiency index and fixation method of internal fixation materials.Result:3 months after surgery,masticatory efficiency and bite force of the observation group were higher than those of the reference group(P<0.05).The fracture healing time of the observation group was shorter than that of the reference group,and the effective rate of the observation group was 93.88%,which was higher than 73.47%of the reference group(P<0.05).The incidence of complications of the observation group was 10.20%,which was lower than 28.57%of the reference group(P<0.05).3 months after surgery,masticatory efficacy indexes were positively correlated with fixation methods and therapeutic effects of internal fixation materials,while masticatory efficacy indexes were negatively correlated with fracture healing time(P<0.05).Conclusion:The treatment of jaw fracture
