摘　　要：目的:应用锥形束CT对新疆地区维吾尔族和汉族成年人下颌骨副孔解剖位置进行回顾性研究,为临床操作提供理论参考。方法:选取2020年1月-2021年12月在新疆医科大学第五附属医院口腔科就诊的300例维吾尔族和汉族成年人CBCT影像资料,对下颌骨进行分区,获得各副孔的相应位置、直径及其到牙槽嵴顶的距离,分析性别、民族、年龄与副孔发生情况的关系。结果:300例成年人的影像中共找出1361个副孔,维吾尔族686个,汉族675个,副孔发生率100%,人均(4.54±1.58)个。在舌侧前部发生率最高,维吾尔族为85.7%,汉族为81.9%,副孔的发生与性别、民族、年龄差异无统计学意义。维吾尔族副孔的直径为(0.79±0.23)mm,汉族为(0.70±0.19)mm,维吾尔族中副孔直径≥1 mm占15.74%,汉族中副孔直径≥1 mm占13.48%,直径比较差异有统计学意义(P<0.001)。维吾尔族副孔到牙槽嵴顶的距离为(12.65±9.35)mm,汉族为(13.15±8.01)mm,差异无统计学意义(P=0.058)。在副孔高发的舌侧前部区域,颏嵴上和颏嵴下差异均有统计学意义(P<0.05)。结论:新疆地区成年人群中均存在副孔现象,术前应仔细核对CBCT影像,术中避免损伤副孔结构,减少并发症的发生。Objective To retrospectively study the anatomic position of accessory foramen of mandible in Uygur and Han adults in Xinjiang by cone beam CT,and provide theoretical reference for clinical operation.Methods The CBCT images of 300 Uigur and Han adults who visited the Department of Stomatology of the Fifth Affiliated Hospital of Xinjiang Medical University from January 2020 to December 2021 were chosen.According to the mandibular division,the corresponding position,diameter and distance to the alveolar crest of each accessory foramen were obtained,and the relationship between sex,ethnicity,age and the occurrence of accessory foramen was analyzed.Results A total of 1361 accessory foramen were found in the images of 300 adults,including 686 Uighurs and 675 Han Chinese.The incidence of accessory foramen was 100%,(4.54±1.58)per capita.The incidence of accessory foramen was the highest in the anterior lingual region,with 85.7%in Uygur and 81.9%in Han.There was no significant difference between the incidence of accessory foramen and gender,ethnicity and age.The diameter of accessory foramen was(0.79±0.23)mm in Uygur and(0.70±0.19)mm in Han.The diameter of accessory foramen≥1 mm accounted for 15.74%in Uygur and 13.48%in Han nationality,with statistical difference(P<0.001).The distance from accessory foramen to alveolar crest was(12.65±9.35)mm in Uygur and(13.15±8.01)mm in Han,with no statistical difference(P=0.058).In the lingual anterior region with high incidence of accessory foramen,there were significant differences between supra and infra chin ridges(P<0.05).Conclusion Most adults in XinJiang have mandibular accessory foramen.CBCT images should be carefully read before operation to avoid injury of accessory foramen structure and reduce complications.
