山羊上颌窦及额窦黏膜厚度对比观察

Comparative Study on Mucosal Thickness of Maxillary Sinus and Frontal Sinus in Goats

目的 探讨山羊鼻窦（上颌窦及额窦）黏膜的厚度差异并分析其原因,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）上切取适当大小黏膜置于固定液中,24 h后制成组织切片,在带有刻度目镜的光学显微镜下观察,镜下随机选取三处读数并记录.结果 山羊上颌窦顶黏膜厚度为410.03士65.97 μm,窦底黏膜为461.33±91.37 μm,额窦黏膜为216.90±46.47 μm,上颌窦顶与额窦、上颌窦底与额窦、窦顶与窦底黏膜厚度均值之间差异均有统计学意义（P＜0.05）.结论 上颌窦顶、底黏膜较额窦黏膜厚,上颌窦底黏膜较窦顶黏膜稍偏厚.

Objective To explore the differences of mucosal thickness in goat paranasal sinus, and analyse the underlying reasons. The discussion can provide theoretical basis and guidance for issues related to mucosa in the practice of maxillary sinus floor augmentation. Methods The mucosa was cut into desired size from every sinus mucosa and fixed in formalin to get the tissue specimens, and observed under optical microscope with scaled eyepiece. Randomly selected three fields under the microscope from the samples and then measured and recorded. Paired t-test was used to determine the difference between the parameters, P〈0.05 was regarded as statistically significant. Results Goat maxillary sinus mucosal thickness of the top was 410.03 ± 65.97 μm, the bottom was 461.33 ± 91.37 μm, the frontal sinus mucosa was 216.90±46.47 μm. The mean differences of mucosal thickness between the top of the maxillary sinus and the frontal sinus, the bottom and the frontal, the top and the bottom were statistically significant （P〈0.05）. Conclusions The top and bottom mucosal thickness of maxillary sinus was thicker than the frontal sinus mucosa, and the bottom mucosal thickness was slightly thicker than the top.
