This report describes maxillary antral pseudocyst drift after maxillary sinus floor augmentation through osteotome sinus floor elevation with simultaneous implant placement. 3D Slicer was used to measure the pseudocyst and maxilla for the placement of the implants; follow-up visits were scheduled at 6, 12, and 22 months. No adverse effects were observed during or after surgery, and all implants exhibited osseointegration without mobility. At 6 months after surgery, the pseudocyst had moved posterolaterally from the preoperative position near the anterior medial maxillary sinus, then returned to its original position at 12 months. However, it had remigrated to the posterolateral position at 22 months. The preoperative volume of the pseudocyst was 3.795 mm; it was 2.370, 3.439, and 2.930 mm at 6, 12, and 22 months after surgery, respectively. The changes in pseudocyst drift and volume did not have a substantial negative influence on the implants, presumably because of cystic attachment and the recurrence of multiple pseudocysts at different locations. The risks associated with changes in a pseudocyst can be avoided, if an appropriate treatment plan is selected.
本报告描述了通过骨凿提升上颌窦底并同期植入种植体进行上颌窦底提升术后上颌窦假性囊肿的移位情况。使用3D Slicer测量假性囊肿和上颌骨以确定种植体的植入位置；安排在术后6个月、12个月和22个月进行随访。手术期间及术后均未观察到不良反应，所有种植体均表现出骨整合且无松动。术后6个月，假性囊肿从术前位于上颌窦前内侧附近的位置向后外侧移动，然后在12个月时回到其原始位置。然而，在22个月时它又重新移至后外侧位置。术前假性囊肿的体积为3.795立方毫米；术后6个月、12个月和22个月时分别为2.370立方毫米、3.439立方毫米和2.930立方毫米。假性囊肿的移位和体积变化对种植体没有实质性的负面影响，推测是由于囊肿附着以及不同位置多个假性囊肿的复发。如果选择合适的治疗方案，可以避免与假性囊肿变化相关的风险。
