目的探讨新疆地区维吾尔族与汉族患者上颌窦相关线性距离的差异性。方法选取2014年6月-2015年6月新疆医科大学第一附属医院维吾尔族及汉族CBCT影像,测量上颌窦垂直向及近远中向线性距离并进行比较。结果汉族患者上颌窦近远中径的平均距离右侧为(29.1±5.31)mm,左侧为(29.0±4.92)mm;维吾尔族患者右侧为(30.6±4.98)mm,左侧为(30.7±4.74)mm,差异有统计学意义(P<0.05)。女性患者上颌窦近远中径中,汉族患者右侧为(28.9±4.14)mm,左侧为(29.1±4.59)mm;维吾尔族患者右侧为(31.0±4.78)mm,左侧为(31.1±4.70)mm,差异有统计学意义(P<0.05)。汉族患者上颌窦颊腭径的平均距离右侧为(22.5±4.58)mm,左侧为(23.0±4.63)mm;维吾尔族患者右侧为(22.59±4.46)mm,左侧为(23.4±4.55)mm,差异无统计学意义(P>0.05)。汉族患者窦底至牙槽嵴顶的平均高度(residual bone high,RBH)右侧为(9.2±3.86)mm,左侧为(9.2±3.73)mm;维吾尔族患者右侧RBH的平均高度为(9.5±3.53)mm,左侧为(9.1±3.29)mm。汉族缺牙患者右侧RBH为(7.9±4.08)mm,左侧为(6.9±3.41)mm;维吾尔族患者右侧RBH为(7.8±4.46)mm,左侧为(7.7±3.76)mm,差异均无统计学意义(P>0.05)。结论维吾尔族患者上颌窦解剖结构中除上颌窦内壁近远中径大于汉族外,其余结构均基本一致。
Objective To investigate the difference of linear distance of maxillary sinus between Uygur and Han nationality in Xinjiang. Methods From June 2014 to June 2015, Uygur and Han CBCT images of the First Affiliated Hospital of Xinjiang Medical University were selected to measure the vertical distance, the mesial distance and the midline distance of maxillary sinus. Results The mean distances between maxillary sinuses and maxillary sinuses were (29.1 ± 5.31) mm on the right and (29.0 ± 4.92) mm on the left, and (30.6 ± 4.98) mm on the left and (30.7 ± 4.98) mm on the left ± 4.74) mm, the difference was statistically significant (P <0.05). In the proximal and distal maxillary sinus of female patients, the right side of Han patients was (28.9 ± 4.14) mm and the left side was (29.1 ± 4.59) mm; the right side of Uygur patients was (31.0 ± 4.78) mm and the left side was (31.1 ± 4.70) mm, the difference was statistically significant (P <0.05). In the Han nationality, the average distance between the maxillary sinus buccal and palatal pathways was (22.5 ± 4.58) mm on the left and (23.0 ± 4.63) mm on the left. Uigur patients had (22.59 ± 4.46) mm on the right and (23.4 ± 4.55) on the left ) mm, the difference was not statistically significant (P> 0.05). In the Han nationality, the mean height at the bottom of the sinus to alveolar ridge was (9.2 ± 3.86) mm on the right side and (9.2 ± 3.73) mm on the left. The mean height of RBH on the right side of Uighur was ( 9.5 ± 3.53) mm, left (9.1 ± 3.29) mm. In the Han nationality, the RBH was (7.9 ± 4.08) mm on the right side and (6.9 ± 3.41) mm on the right side, while the RBH on the right side was (7.8 ± 4.46) mm on the Uygur nationality and (7.7 ± 3.76) mm on the left side, No statistical significance (P> 0.05). Conclusion The anatomic structure of maxillary sinus in Uygur patients is similar to the other structures except that the mesial wall of maxillary sinus is larger than that of Han people.
