摘　　要：目的:通过观测乌鲁木齐地区200例成人锥形束CT(Cone bean Computer Tomography)图像,获取颏孔区的解剖学数据,为该区域种植手术及外科手术提供参考依据。方法:选取200例于新疆医科大学第一附属医院口腔科就诊患者的CBCT图像,由两名专业的口腔医生对颏孔的位置、大小、颏孔的角度、颏孔上缘到牙槽嵴顶的距离及副颏孔的发生率等进行观测,所得数据导入SPSS17.0进行统计学分析。结果:所有观察对象均显示颏孔,颏孔位置53.5%位于第一第二前磨牙之间,31.3%位于第二前磨牙根方,男性颏孔横径为(3.41±0.54)mm,纵径为(2.72±0.46)mm,女性颏孔横径为(3.11±0.43)mm,纵径为(2.49±0.49)mm,左侧颏孔的平均角度为(45.1±10.05)°,右侧颏孔的平均角度为(43.8±7.9)°,颏孔上缘到牙槽嵴顶的距离(14.19±1.46)mm,副颏孔的发生率7.5%。结论:乌鲁木齐地区成人颏孔位置有差异,副颏孔的发生率较高,在进行该区域手术时,术前应拍摄CBCT进行仔细观测,对减少术中出血、神经损伤等并发症具有一定的指导意义,以确保该区域的手术安全性。Objective To calculated anatomical data of the mental foramen regions by observing 200 cases of CBCT images of adults in Urumqi,in order to provide reference for implantation and surgical operations in this area. Methods 200 adults who visited Stomatology Department of the First Affiliated Hospital of Xinjiang Medical University were selected.they were scanned by CBCT.The position, size, angle of the mental foramen, distance from the upper edge of the mental foramen to the crest of alveolar ridge and incidence of accessory mental foramen were observed by two professional stomatologists. The data were imported into SPSS17.0 for statistical analysis. Results All subjects showed mental foramen. 53.5% of the mental foramen was located between the first and second premolar, 31.3% was located at the apical of the second premolar. The transverse diameter of the male mental foramen was (3.41±0.54)mm, the longitudinal diameter was (2.72±0.46)mm, the transverse diameter of the female mental foramen was (3.11±0.43)mm, the longitudinal diameter was (2.49±0.49)mm. The average angle of the left mental foramen was (45.1±10.05)°,The average angle of the right mental foramen was(43.8±7.9)°,The distance from the upper edge of the mental foramen to the crest of the alveolar ridge was (14.19±1.46) mm, and the incidence of accessory mental foramen was 7.5%. Conclusion The location of mental foramen in Urumqi adults is different ,and the incidence of accessory mental foramen is high.CBCT should be taken carefully before operation in this area. It has certain guiding significance to reduce complications,such as intraoperative hemorrhage and nerve injury, so as to ensure the safety of operation in this area.
