This study measured maxillary sinus volume as an aid in determining the volume of graft bone needed before grafting autogenous bone to the maxillary sinus floor. Maxillary sinus volumes were measured from computerized tomographic images of 38 sinuses using a 3-dimensional reconstruction system. When the sinus-lift procedure was simulated, volumes (mean +/- SD) of the inferior portion of the sinuses were 4.02 +/- 1.44 cm3 for 15-mm lifting and 6.19 +/- 1.77 cm3 for 20-mm lifting. In bone grafting of the maxillary sinus floor, taking into consideration individual differences in maxillary sinus volume and resorption of the grafted bone, 5.46 cm3 or more were required for a 15-mm lift and 7.96 cm3 or more were required for a 20-mm lift.
本研究测量上颌窦容积，以辅助确定在上颌窦底植入自体骨之前所需的移植骨体积。使用三维重建系统，从38个鼻窦的计算机断层扫描图像中测量上颌窦容积。当模拟鼻窦提升手术时，鼻窦下部的容积（平均值±标准差）在提升15毫米时为4.02±1.44立方厘米，在提升20毫米时为6.19±1.77立方厘米。在上颌窦底植骨时，考虑到上颌窦容积的个体差异和移植骨的吸收情况，提升15毫米需要5.46立方厘米或更多，提升20毫米需要7.96立方厘米或更多。
