上颌窦内提升对上颌窦底黏膜的影响:基于CBCT的影像学研究

Influences of Internal Sinus Elevation on Sinus Membrane:CBCT Based Radiographically Evaluation

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 prooperation.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.
