Sinus floor augmentation has been established as a predictable technique to overcome maxillary bone loss. Antral cystic lesions may lead to intrasurgical complications and should be accurately diagnosed. However, antral pseudocysts have recently been described not to be contraindicated for sinus-grafting procedures. The current article sought to report clinical, cone beam computed tomographic, and histologic results of a maxillary sinus floor augmentation, performed with piezoelectric surgery, in the presence of a large antral pseudocyst. Success of graft maturation was confirmed with histologic analysis, which also indicated the absence of inflammatory infiltration in the tissue evaluated. On the basis of our findings, it is possible to perform a predictable treatment based on sinus floor augmentation in the presence of antral pseudocysts. Graft maturation can also be achieved 6 months after sinus-lifting surgeries.
上颌窦底提升术已被确立为一种可预测的技术，用于克服上颌骨缺失。鼻窦囊性病变可能导致手术中的并发症，因此应准确诊断。然而，最近有研究表明鼻窦假性囊肿并非鼻窦植骨手术的禁忌证。本文旨在报告在存在大型鼻窦假性囊肿的情况下，使用压电手术进行上颌窦底提升术的临床、锥形束计算机断层扫描和组织学结果。组织学分析证实了植骨成熟的成功，这也表明在所评估的组织中没有炎症浸润。基于我们的研究结果，在存在鼻窦假性囊肿的情况下，可以基于上颌窦底提升术进行可预测的治疗。鼻窦提升手术后6个月也可实现植骨成熟。
