青海地区成人上颌窦间隔锥形束CT的研究分析

Analysis of Maxillary Sinus Septa in Population of Qinghai by Cone-beam CT

目的:通过锥形束CT(CBCT)结合测量软件,研究青海地区成人上颌窦间隔的解剖学变化。方法:选取300例成人研究对象的CBCT影像资料,测量分析上颌窦间隔的发生、位置、高度、方向及形态学变化。用SPSS17.0软件对数据进行统计学分析。结果:300例研究对象中,有80例出现上颌窦间隔,发生率为26.7%;窦间隔的发生与性别、年龄及牙缺失无关。窦间隔主要出现在上颌窦中部(41.4%);平均高度右侧(6.60±4.08)mm,左侧(6.81±4.24)mm;平均长度右侧(9.28±2.99)mm,左侧(9.00±3.00)mm;颊腭向多见(85.2%),完全性为主(80.5%)。结论:青海地区成人中有26.7%出现上颌窦间隔,在上颌窦底提升术时应予以重视,采取适当的对策。

Objective：To investigate the anatomical variation of maxillary sinus septa by cone-beam CT and provide guidance to sinus floor elevation.Methods：Cone-beam CT scans of 300 adult subjects were evaluated to assess the prevalence,location,height,orientation,and morphology of the maxillary sinus septa.The data were analyzed with SPSS17.0.Results：Sinus septa were present in 80 out of 300subjects（26.7%）.The prevalence of septa was not significantly correlated with gender,age,and presence of tooth loss.41.4% of the septa were located in the middle of maxillary sinus.The mean height of sinus septa was（6.60±4.08）mm and（6.81±4.24）mm in the right and left maxillary sinus,respectively.The mean length of sinus septa was（9.28±2.99）mm and（9.00±3.00）mm in the right and left maxillary sinus,respectively.85.2% of the septa orientated buccopalatally.80.5% of the septa were complete.Conclusion：26.7% of population in Qinghai have maxillary sinus septa.Much more attention should be paid in maxillary sinus floor elevation to avoid complications.
