汉族人群腭大孔解剖位置及其与腭穹隆形态关系的CBCT研究

Anatomical variation of the greater palatine foremen and its relationship with palatal vault morphology in Han population studied by CBCT

目的:研究汉族青年人群腭大孔解剖位置及其与腭穹窿形态的关系。方法:采用CBCT测量209名18~45岁汉族受试者腭大孔的相对位置及毗邻关系,并讨论腭穹窿形态对腭大孔位置的影响。结果:腭大孔在第三磨牙近中、腭侧和远中的分布率分别是17.22%、64.59%和18.18%。男性与女性腭大孔至腭中缝(GPF-MMS)的距离分别为(16.29±1.47)mm和(15.60±1.35)mm,腭大孔至牙槽嵴顶(GPF-AC)的距离为(14.02±2.69)mm和(12.29±2.41)mm。GPF-MMS的距离在腭高耸组中明显低于腭低平组;相反,GPF-AC的距离在腭高耸组中明显高于腭低平组。结论:汉族青年人群腭大孔的位置与患者腭穹隆形态和性别有关。

Objective： To investigate the anatomical variability of greater palatine foremen （GPF） and to explore the its relationship with palatal vault morphology in young HaM population. Methods： Cone-beam computerized tomography （CBCT） images of 209 patients aged 18 -45 years were measured. The relative locations of GPF were evaluated and its relationship with palate vault morphology was analyzed. Results： The distribution rates of GPF in the mesial, palatal and distal of third molar were 17.22% , 64.59% and 18.18% , respectively. In men and women, the mean distance between the GPF and the MMS （GPF-MMS） were （ 16.29 ± 1.47） mm and （15.60 ±1.35 ） mm while the mean distance between the GPF and the alveolar crest （GPF-AC） were （14.02 ± 2.69） mm and （12.29 ±2.41 ） mm, respectively. The GPF-MMS distance was significantly shorter in high-vauh group than that in low-vault group. In contrast, the GPF-AC distance was significantly longer in high-vauh group. Conclusion： The GPF position in young HaM population is related to the gender and the palatal vault morphology.
