摘要：

背景：有学者专门就曲面断层片下颌骨的研究测量方法进行了详尽阐述，随生长发育上颌窦底相对鼻中隔与硬腭交点的相对位置变化尚未见相关报道。
目的：测量4~14岁儿童生长发育过程中上颌窦底的位置变化。
方法：选择乌鲁木齐市口腔医院就诊的300例4~14岁儿童，将收录的人群按Hellman’s牙齿发育阶段分为5组，ⅡA组：完全的乳牙阶段；ⅡC组：第一恒牙萌出阶段；ⅢA组：乳切牙到恒切牙的过渡阶段；ⅢB组：乳后牙(包括尖牙到磨牙)到恒后牙(包括尖牙到第二前磨牙)的过渡阶段；ⅢC组：第二恒磨牙的萌出阶段。通过Auto-CAD计算机辅助设计软件对全颌曲面断层片进行画图分析，定鼻中隔与硬腭的交点为O点，硬腭与上颌窦近中面的交点为PA点，将两点连成一线定位X轴，过O点并与X轴垂直的为Y轴，此时O点为(0，0)点，对上颌窦最低点(S)进行定点，此点会有一个精确的坐标值即(SX，SY)，将数据进行统计分析。
结果与结论：ⅡA组与其他各组SX点相比，差异均有显著性意义(P < 0.01)；ⅡC，ⅢA，ⅢC组之间无显著性差异(P> 0.05)；ⅢB组与ⅢC组之间差异有显著性意义(P < 0.01)。SY点除ⅡA组与ⅡC组之间无差异外(P > 0.05)，其余各组之间差异均有显著性意义(P < 0.01)。上颌窦底是向外向下，向内下侧的方向生长。

Abstract:

BACKGROUND: Some scholars have specifically recounted the mandible measurement methods based on panoramic radiographs. However, there are no reports regarding the localization changes of the maxillary sinus floor. 
OBJECTIVE: To investigate the changes of maxillary sinus floor localization from 300 children of 4-14 years old during the growth and development.
METHODS: The materials for this investigation comprised panoramic radiographs of 300 children (150 girls and 150 boys) whose ages ranged from 4 to 14 years. The materials were divided into five groups according to Hellman’s dental developmental stages. Auto-CAD (CAD-computer Aided Design) software was used to analyze the panoramic radiographs. The tracing of each radiograph was digitized by translating the reference points onto an X-Y coordinate system. The straight line that passes point O (the point that nasal septum intersects with hard palate) and point PA (the point that medial wall of maxillary sinus intersects with hard palate) was designated as the X axis. The straight linevertical to the X axis and passing through point O at a rightangle was designated as the Y axis. The X and Y coordinate values of reference point were calculated. And then O point was (0, 0), the maxillary sinus floor localization (S) was (SX, SY).
RESULTS AND CONCLUSION: There were no significant differences between males and females from group 1 to group 5 in (SX, SY) (P > 0.05). The differences between group 1 and other groups were significant in SX (P < 0.01), But 2, 3, 5 groups had no significant differences, there were significant differences between group 4 and group 5 (P < 0.01). There were significant differences in SY among 2, 3, 4, 5 groups (P < 0.01), but group 1 and group 2 had no significant differences (P > 0.05). The position of maxillary sinus floor grew downward and outward with age.
