目的:通过CBCT影像学手段,测量和分析上颌窦内提升术对上颌窦黏膜的影响.方法:纳入因上颌后牙缺失行上颌窦内提升术的25例患者共36侧上颌窦.其中男11例,女14例,平均年龄(45.32±11.34)岁.结果:术前上颌窦底黏膜厚度0.65~3.56mm,平均(0.45±0.55)mm,术后上颌窦底黏膜厚度2.31~6.54mm,平均(3.64±1.02)mm,术后黏膜厚度较术前显著增加,差异具有显著性(P<0.05).结论:上颌窦内提升术可导致术后上颌窦黏膜的暂时性增厚,但未对预后产生明显影响.%Objective To evaluate influences of internal sinus elevation on sinus membrane by using CBCT from pre to pro-operation. Methods All CBCT scans were input simplant software. The Schneiderian Membrane Thickness(MT) of the sinus floor was evaluated. Results Based on pre-surgery CBCT scans,Membrane thickness was (1.45±0.55)mm,0.65-3.56mm. On pro-surgery CBCT scans,Membrane thickness was (3.64±1.02)mm,2.31-6.54mm.The Schneiderian membrane exhibited significant swelling immediately after surgery (P<0.05). Conclusion Except postoperative transient swelling showing CBCT. Internal sinus elevation may not be affect the sinus membrane.
