摘要:

目的 在陡峭羊上颌窦行经牙槽嵴顶的上颌窦底内提升术,使用0.012、0.014型号新型记忆弹性丝套管剥离器以及伞形剥离器剥离窦底黏膜,测量剥离长度,对比剥离效果。方法 经羊头颅计算机体层摄影选择窦底有60°~90°坡度的山羊,建立动物模型72个,并随机分成3组(n=24):A(0.012型号)、B(0.014型号)、C(伞形剥离器)组。冲顶后行经牙槽嵴上颌窦底黏膜的剥离,待达到剥离极限或黏膜穿孔时测量剥离长度。结果 A组剥离黏膜的平均长度为11.3 mm±4.6 mm,3例出现上颌窦黏膜穿孔;B组剥离黏膜的平均长度为17.5 mm±5.0 mm,1例出现上颌窦黏膜穿孔;C组剥离黏膜的平均长度为4.2 mm±1.3 mm,4例出现上颌窦黏膜穿孔。经方差分析得3组总体均值不全相同(P<0.01),再通过Dunnett’s T3检验得出,3组剥离窦底黏膜长度的均数两两比较差异均有统计学意义(P<0.05)。结论 新型记忆弹性丝套管剥离器能够有效剥离陡峭的上颌窦底黏膜,而0.014型号剥离效果更好,且相对安全。

Abstract:

Objective This work aims to investigate the effect of stripping of steep sheep maxillary sinus by using 0.012 or 0.014 model new-type memory elastic silk sleeve stripper and umbrella stripper. Methods Goats with sinus floor gradients of 60° to 90° were selected by computed tomography of sheep head. A total of 72 animal models were established and rando-mized into three groups (n=24): group A (0.012 model), B (0.014 model) and C (umbrella stripper). Alveolar and maxillary sinus mucosa were stripped after crowning, and stripping length was measured when the stripping limit was reached or mucosal perforation occurred. Results The average stripping length of mucosa in group A was 11.3 mm±4.6 mm, and three cases experienced perforation of sinus floor mucosa. The average stripping length of mucosa in group B was 17.5 mm±5.0 mm, and one case experienced perforation of sinus floor mucosa. The average stripping length of mucosa in group C was 4.2 mm±1.3 mm, and four cases experienced perforation of sinus floor mucosa. The difference among the three groups was statistically significant (P<0.01) according to variance analysis. Moreover, the comparison between any two means was also statistically significant according to Dunnett’s T3 test (P<0.05). Conclusion The new-type memory elastic silk sleeve stripper effectively stripped steep maxillary sinus mucosa. The 0.014 model exhibited superior peeling effect and was relatively safe.
