摘　　要：目的探讨山羊鼻窦黏膜的抗拉伸强度的差异并分析差异产生原因,为上颌窦提升术中涉及黏膜问题时提供理论依据和指导。方法从获取的每块鼻窦黏膜(上颌窦顶、上颌窦底及额窦黏膜)上切取所需大小的黏膜,以弹簧测力计及自制夹具测得抗拉伸强度数值,结果采用单因素方差分析。结果山羊上颌窦顶黏膜抗拉伸强度为(4.68±0.94)N;上颌窦底为(5.27±1.12)N;额窦为(1.97±0.46)N。上颌窦顶与额窦、上颌窦底与额窦黏膜抗拉伸强度的差异有统计学意义(P<0.05),上颌窦顶与窦底黏膜抗拉伸强度的差异无统计学意义(P>0.05)。结论上颌窦顶、底黏膜均较额窦黏膜抗拉伸强度大,上颌窦顶黏膜与上颌窦底黏膜抗拉伸强度无差异。Objective To explore the differences of the membrane ductility of goat paranasal sinus membrane and analyze the reasons that may cause these differences and to provide theoretical basis and guidance for the issues of the maxillary sinus floor augmentation related to the membrane. Methods The membrane was cut into desired size from every sinus membrane. The ductility data were measured by using the push-pull gauge and the homemade fixtures. The results were analyzed by One-way AINOVA. Results Goat maxillary sinus membrane ductility of the top was（ 4. 68 ± 0. 94） N,that of the bottom was（ 5. 27 ± 1. 12） N,and the frontal sinus membrane was（ 1. 97 ± 0. 46） N. The mean differences of membrane ductility between the top of the maxillary sinus and the frontal sinus,the bottom and the frontal were statistically significant（ P〈0. 05）,while the top and the bottom were not statistically significant（ P〉0. 05）. Conclusion The top and bottom membrane ductility of maxillary sinus is bigger than that of the frontal sinus membrane.There is no difference between the top and the bottom membrane ductility of maxillary sinus.
