摘要
目的探讨山羊上颌窦及额窦黏膜的厚度及可承受压强的差异,并分析造成这种差异的可能原因,为上颌窦提升术中涉及黏膜问题时提供理论依据和指导。方法从获取的每块黏膜上切取2块所需大小的黏膜,中性甲醛溶液固定24 h后,将黏膜制成组织切片,用于测量黏膜厚度,另一块黏膜用于可承受压强数值的测定,再进行二者相关性的分析,选择合适的统计方法和软件。结果山羊上颌窦顶、上颌窦底、额窦黏膜厚度分别为(410.03±65.97)、(461.33±91.37)、(216.90±46.47)μm。山羊上颌窦顶、上颌窦底、额窦黏膜可承受压强分别为(260.08±80.12)、(306.90±94.37)、(121.72±31.72)k Pa。上颌窦顶与额窦、上颌窦底与额窦、上颌窦顶与窦底黏膜的厚度均值之间差异有统计学意义(P<0.05),可承受压强均值之间差异也有统计学意义(P<0.05)。结论上颌窦顶、底黏膜较额窦黏膜厚度及可承受压强均大,上颌窦底黏膜较上颌窦顶黏膜厚度和可承受压强稍偏大,并且窦黏膜可承受压强与黏膜厚度之间成正相关关系。
Objective This study aimed to explore the differences of membrane thickness and pressure on the paranasal sinus membrane in goats and analyze their causes. The results can provide theoretical basis and guidance for the issues of the maxillary sinus floor augmentation related to the membrane. Methods The membrane was cut into two sizes from every sinus membrane. The membrane was fixed in formalin to obtain tissue specimens for the membrane thickness study and pressure study. The correlation between the two parameters was then analyzed, and appropriate statistical methods and software were selected. Results The top of maxillary sinus, the bottom of maxillary sinus and the frontal sinus membrane thickness were （410.03±65.97）, （461.33±91.37）, （216.90±46.47） μm. The pressure were （260.08±80.12）, （306.90±94.37）, （121.72±31.72） kPa. The mean differences of the membrane thickness between the top of the maxillary sinus and the frontal sinus, bottom and frontal, and top and bottom were statistically significant （P〈0.05）. The mean differences in membrane pressure were also statistically significant （P〈0.05）. Conclusion The membrane thickness and pressure of the top and bottomof the maxillary sinus are higher than those of the frontal sinus membrane. However, the thickness and pressure of the bottom membrane are slightly higher than those of the top membrane. Pressure and membrane thickness are posi- tively correlated in the sinus membrane.
