摘要： 目的: 回顾性研究下颌尖牙萌出前后,儿童颌部骨折的骨折线位置变化情况,探索下颌尖牙的萌出与儿童颏部骨折的关系和儿童颏部骨折的新特点。方法: 首先界定颏部骨折范围,然后收集武汉大学口腔医院口腔颌面外科2012年5月1日~2016年5月1日间因颏部骨折(可合并其他部位骨折)而就诊的儿童(年龄≤12岁),根据影像资料判断骨折线位置与尖牙牙胚、正中联合、颏孔的关系。记录患者术后复诊情况、复诊时间,对于未复诊患者采取电话联系方式询问患者愈后恢复情况。采用统计软件将以上数据准确统计并进行分析。结果: 一共有80名儿童符合要求进而纳入此研究,其中男57人,女23人,性别比例为2.47∶1。受伤原因以不慎摔倒为最主要原因(51.2%)。下颌尖牙未萌出患者中以骨折线位于尖牙牙胚和正中联合为主,分别占66.17%和39.70%。下颌尖牙已萌出患者中以骨折线位于正中联合为主,12人中有8例,占66.66%。下颌尖牙萌出前后,骨折线发生在尖牙胚的概率有统计学差异(P=0.003<0.05)。治疗方法与颏部骨折愈后情况无统计学差异(P=1.000)。结论: 男童比女童更易发生颏部骨折,其中最容易引起颏部骨折的原因是不慎摔倒。儿童颏部骨折的骨折线位置会随着下颌尖牙是否萌出而有所改变,在下颌尖牙未萌出时,骨折易发生在尖牙牙胚附近累及尖牙;一旦下颌尖牙萌出,骨折便不再容易发生在尖牙附近,以累及正中联合为主。综合患儿术前受伤情况、是否伴有并发症和家属意愿来决定治疗方式,可以达到很好的治疗效果。

Abstract: Objective: To explore the characteristics of chin fractures and the association between the eruption of mandibular canines and the chin fractures in children through the investigation of fracture line position in the chin fracture before and after the eruption of the mandibular canine in children, retrospectively. Methods: Eighty children (age≤12 years old) were collected who were suffered chin fracture (or combined fracture of other parts) from May 2012 to May 2016 in Stomatological Hospital of Wuhan University. The association between the fracture line position and canine tooth germs, median joint, mental foramen was defined by radiological information. The prognosis after operation was recorded. All data were accurately and analyzed using statistical software. Results: A total of 80 children were enrolled in this study, including 57 men and 23 women, with a sex ratio of 2.47:1. The main cause of the injury was inadvertent fall (51.2%). 66.17% of the fracture lines in the non-erupted mandibular canine were on the canine tooth germ, and only 16.67% of the fracture line in the eruption of the canine on the canine. There was statistically significant difference between groups of fracture line in the canine tooth germ and after the eruption of mandibular canine(P=0.003<0.05). There was not statistically significant difference between surgery groups and conservative group (P=1.000). Conclusion: Boys are more likely to have chin fractures than girls. The most important reason is the inadvertent fall. The fracture line of children's chin fracture will change with the eruption of the mandibular canine. If the mandibular canine is not erupted, the fracture will easily occur near the canine tooth germ. However, the fracture was not easily to occur near the canine after the mandibular canine eruption.
